Edmonton Valve has been offering a variety of courses over the years, from teaching about fitting installation to improving sampling system performance, we've got you covered. Download our free training catalogue today and find a training class to suit your teams development.

Training & Education


What do valves, fittings, gauges and most other Swagelok components have in common? They need tubing in order to be of any use in a fluid system. Without tubing, all you'd have is a pile of parts.

It's vital, then, to understand how to handle tubing, plan a route for it, cut the correct length of tubing and bend it accurately.

There's not need to learn by trial and error. There's no need to wonder if your co-workers are passing along any bad habits if you rely on them to show you want to do. Rely instead on Edmonton Valve & Fitting. Our four-hour Tube Bending Essentials class on tube bending will show you what you need to know. With guidance from a certified expert, you'll learn how to consistently make optimal tube bends, and do the work efficiently.

What we cover

We start at the beginning: How to handle tubing without damaging it. We'll show you how to properly cut and debur the tubing as well as how to bend it. You'll learn how to calculate the length of tubing you need to get from Point A to Point B. That's especially important when you are using expansion loops and offsets, which we'll also cover.

Good craftsmanship not only saves money by reducing the amount of expensive scrap, it also improves fluid system performance.

The course has hand-on exercises as well as classroom instruction, so you'll be able to practice what you just learned. 

Who should attend

Anyone who has to install tubing can benefit from this course: fabricators, contractors and technicians. But it's also valuable knowledge for people who design fluid systems: engineers and draftsmen. Anyone responsible for inspecting or maintaining a fluid system also needs to know if the job was done right: quality control personnel and safety engineers.

Tube Bending Essentials is only one of many classes that we offer. You can contact us through the linked page to sign up for the next class in our new training center, or we can bring the class to your location. If you prefer to talk with a live person, we're at 780-437-0640.

ABSA and MTRs: We Have Your Parts Covered Part 2

Posted by Alecia Robinson on Tue, Sep 12, 2017 @ 15:09 PM

We have documentation for components for systems running at more than 15 psi


DSC_0232.jpg

Need an MTR for one of your Edmonton Valve orders? Head over to edmontonvalve.com/mtrs to download a copy, all you need is the heat number which is stamped right on your tubing.


As we discussed in an earlier post about ABSA and CRNs, the Alberta Boiler Safety Association is the pressure equipment safety authority authorized by the Alberta Government to administer and delivery safety programs related to boilers, pressure vessels and pressure piping systems through their complete life cycles. In this weeks blog we will discuss how ABSA relates to Swagelok when it comes to Material Test Reports (MTRs).

Documentation

For threaded piping and tubing, ABSA suggests that owner companies have certain procurement and purchasing requirements from its approved vendor list. Although Material Test Reports may not be required by construction code, MTRs may be required in owner specification. So it's up to the owner to train personnel in the MTR verification and other documentation requirements

MTRs and CoCs

Edmonton Valve & Fitting can help out by providing documentation. We provide MTRs for all tubing orders. They are based on the heat number printed on the lay line of the tubing. We also have a self-serve option available for MTRs for tubing online at edmontonvalve.com/mtrs. Simply enter the heat number and you can download the MTR. If you are cutting the tubing, then the heat number should be written onto the tubing

MTRs are typically not provided with other products, but they are available on request. All parts are traceable for alloy materials with a three-letter heat code that is stamped onto all fitting components which meets the ABSA requirement. It speeds up the process if you request the MTR at the time of order.  Keep in mind that a tubing tee could have up to 10 MTRs associated with it.

Another commonly requested document we receive is a Certificate of Compliance. We can provide a Certificate of Compliance upon request, just mention this request when speaking to your customer service associate.  A CoC will be issued for the entire order, and parts are listed out.

Freezing Weather's Almost Gone, But It's Not Forgotten

Posted by Alecia Robinson on Thu, Apr 27, 2017 @ 09:04 AM

Start planning for next winter now with our insulation and tracing packages


insulated & heat trace.png

Edmonton Valve is your single source for tracing products, equipment, and training. To find out more about our line download the Pre-Insulated Tubing Bundles Catalogue.


Now that the weather is warming up around Edmonton, it's tempting to forget about the cold-weather hassles we're leaving behind. But you know better. You know that this is the time to start thinking about how you'll make improvements before next winter comers.

Edmonton Valve & Fitting makes it easier because we can be your single-source supplier for heat tracing and insulation packages. It starts with the tubing itself: bare coil tubing, traced tubing, and insulated tubing. We also have pre-insulated tubing, banding and clips, heat transfer compounds, steel tags, heat shrink boots, fluid distribution headers, valves, and of course all the tube fittings and unions you need to complete a job.

A dual stage tube straightener is available for rental to complete your job.  This will help get all the kinks out of any bare coil tubing size. 

Whether yours is a glycol, steam or electrical application, you don't have to go to 10 different suppliers, because this is one area where we go beyond Swagelok's product offerings to make sure you have what you need.

Why worry about this now? Because you need to think about coordinating with your planned shutdowns, facility upgrades and capital projects. Most of our clients go for two to five years between shutdowns. If you need to replace steam lines, proper tracing and insulation can't be a last-minute add on.

Get it right

Components can't do their jobs well if they aren't properly installed. Proper training also increases safety and decreases costs. For people who don't spend a lot of time installing and upgrading tracing packages, such as crews for insulating contractors and construction contractors, it's smart to get a refresher. We're here to help on that score as well.

We offer a full-day class each month on tube fitting installation training, a mix of classroom lecture and hands-on practice. The seminar emphasizes choosing correct tubing and fittings for the site, proper handling, preparing, and installing components to specification. Each participant gets to assemble tubing and fittings, then see how their work holds up under pressure in our burst chamber. Pass the class, and you get a certificate of completion that is ABSA recognized. 

Whenever you need to jog you memory, we also have detailed installation instructions in printed form, with reference photos.

So while you are enjoying the warm weather, make plans to keep everything running smoothly when it turns cold again. Call Edmonton Valve & Filling at 780-437-0640 or contact us through our website, and we can help you put together the insulation and tracing packages that you need.

Grace Under Pressure: Swagelok's IPT Fittings

Posted by Alecia Robinson on Tue, Jan 10, 2017 @ 09:01 AM

Cone-and-thread fittings make a tight, reliable seal


 IPT Fitting Diagram.png

 The image above highlights the key components of the IPT fitting.The cone and thread fittings are desgined to withstand medium and high pressure environments.

IPT Download


When you have a fluid system running at above-normal pressures, you need something sturdier than the standard Swagelok tube fitting. For great performance under pressure, we have the IPT series. We offer two types of IPT fittings: The medium pressure fittings are designed for up to 20,000 psig or 1378 bar and the high-pressure fittings for up to 60,000 psig or 4134 bar.

These cone-and-thread fittings are designed specifically for the oil and gas, chemical, petrochemical, water jet cutting and blasting, and aerospace industries.

A good angle

The threaded tubing ends with a cone at a 59-degree angle. It fits into the primary seal surface, which has a 60-degree angle. All manufacturers use the same interference angle between the male cone and female body, which allows for interchangeability. This is one of the rare times Swagelok gives a green light to mixing its components with those from other manufacturers.

A collar surrounds this area. A threaded part, called a gland, creates a load on the collar to ensure a seal on the tubing. This is another area where standard procedure departs from the standard Swagelok tube fitting. Instead of prescribing a fixed number of turns for proper tightening, IPT fittings require a specific amount of torque.

Another key element in IPT fittings is a weep hole at the collar. It's a quick way to detect leaks and verify proper installation. Even steam leaks are easy to spot by applying a bit of Snoop leak detector at the weep hole. When removing the collar and gland for maintenance, the weep hole also releases trapped pressure to avoid a "live loaded" thread. But never use the weep hole to bleed the system or vent system pressure. This could cause a pressure-injection injury to your employees.

The medium-pressure and high-pressure components have the same basic design, but the parts are not interchangeable. The high-pressure version has a larger collar and gland, and the collar sits inside the gland when assembled. The high-pressure design also uses thicker wall tubing to compensate for threads.

Both the medium-pressure and high-pressure versions have anti-vibration assemblies available. That's useful when the fittings are placed near a compressor, for example. Again, the assemblies are not interchangeable. An easy way to spot the high-pressure version is its additional slotted collet, which must be pointed in the right direction for assembly. (The medium-pressure slotted collet can be oriented in either direction.)

Tough tubing

The special cold-drawn tubing used with IPT fittings is also different from the standard used in other applications. It's harder and has thicker walls in order to allow cutting away material for threads with a tap-and-die set. In a sense it's really a very small pipe. We'll gladly rent you the tools to do the coning and threading, or we can do it for you if you tell us the dimensions you need.

Another difference from ordinary tubing is the outer diameter, which is slightly smaller than the nominal tube OD.

The harder steel and thicker walls also come into play when bending the tubing. The bend radius must be larger, at least 1.25 inches for quarter-inch tubing. (Keep that in mind when planning out your installation, as you'll need some extra space.) Don't try using a hand tube bender; use the bench-top version as you will also experience greater spring back.

Even extra-tough tubing is softened by heat. That means high temperatures (greater than 93.33º C) will have an impact on the pressure rating of the connection. At 204º C, the pressure rating drops to 93 percent of normal for strain-hardened 316 stainless. At 537º C it drops to 84 percent of normal.

Multiple assemblies

If you've properly installed your IPT fittings, you can take them apart and reassemble them up to five times. But it's important to make sure the cone stays perfectly smooth. If the cone doesn't fit tight against the body, you won't get a proper seal. Tubing can be re-coned if you aren't sure, though be aware that doing so can shorten the length of the tubing.

So don't let the pressure get to you the IPT download has even more information on all the types of IPT fittings and ordering information.

Your Checklist for Tubing Quality

Posted by Tristian McCallion on Fri, Dec 09, 2016 @ 11:12 AM

Quality is one of Swagelok's six core values; here we offer up a checklist to make sure you get the best quality out of your tubing and what to look for


Tubing EVF.png

It's important to know what to look for in tubing quality and we have you covered with our checklist below. Still looking for more information on tubing, download our Tubing Data PDF. 

Tubing Data PDF


There are 5 main parts to a tube fitting connection.  Nut, back ferrule, front ferrule, and fitting body are all parts that are manufactured to exacting tolerances and standards at Swagelok.  The fifth component, that Swagelok as a manufacturer has no control over, is the tubing. 

Setting the tubing standards

There are a number of standards that apply to tubing depending on material, but we will focus on the stainless steel specs as this makes up the bulk of what we see being used in northern Alberta.

ASTM sets a number of standards for tubing, so when you get your tubing, it is always a good practice to check the lay line on the tubing for the ASTM standard to which it is manufactured.  It should be printed on the tube, along with the heat number for the tubing.

For stainless steel tubing, ASTM A269 or A213 are common grades.  A269 refers back to ASTM A1016 General Requirements, which gives us the following information:

  • 13.1 – Finished tube shall be reasonably straight and have smooth ends free of burrs.
  • ASTM A269 also gives guidelines for the tolerances of the tubing OD. It is +- 0.005in.  Ovality is allowed to be two times the OD tolerance.

Even with the ASTM specs, there is a lack of standards and there can be variations in the quality of the tubing that you get.  Tubing quality really does depend on the integrity and quality consciousness of the tubing supplier. 

Tubing quality checklist

Before installing any piece of tubing into a Swagelok fitting, the installer should take a moment to take a look at the following items:

  • Is the tubing seamless or welded?  If it is welded are there any signs of corrosion or pitting along the weld bead? Can you see the weld bead on the OD?   If there are, it may create issues.
  • What is the hardness of the tubing?  For best performance with a Swagelok fitting, it is recommended that the tubing not exceed a Rockwell hardness of 90 HRB.
  • Make sure the surface finish is free of scratches.  As the tube fitting seals on the OD of the tubing, scratches can result in potential leak paths.
  • Check for ovality of the tubing.  Oval tubing should not be forced into the tube fitting as it may damage some of the components.
  • Check the OD and ID to make sure they are free of burrs.  A burr on the OD can scratch and damage sealing components.  A burr on the ID can get flushed downstream and damage O-rings or other seals in valves, regulators, or other components.
  • Check the wall thickness to make sure it is sufficient for the pressures that the system will see.
  • Check the tubing for concentricity, that is, check that the wall thickness is consistent all the way around the tubing.  You don’t want a thick wall on the top of the tube and thinner wall on the bottom.

If you have any questions about the quality of the tubing you are using, please contact your local Swagelok supplier.  Edmonton Valve has a number of tools that we can use to help improve the overall quality of your tube fitting connections.

For even more information, the Swagelok Tubing Data Sheet has lots of great information and pressure ratings for most common types of tubing.

Insulated Tubing Gives You Temperature Control

Posted by Katie Reid on Fri, Oct 28, 2016 @ 12:10 PM

Because it differs from ordinary tubing, so do the installation instructions


pre-insulated-tubing.jpg

There are times when ordinary tubing alone won't get the job done. One of those times is when you need to control the temperature of the fluid inside, or control the surface temperature of the tubing itself. That's when you might want to consider insulated tubing - download the catalogue below.

Download Pre-Insulated Tubing


Swagelok insulated tubing is designed for use in applications such as steam supply, condensate return, and gas and liquid transport lines, where weatherproofing and energy conservation are important. It helps protect personnel from hot process and steam lines, reduces heat loss, and offers a cost-effective alternative to field-installed insulation of small-diameter tubing systems.

Tubing lengths and bends

Because the tubing itself is different, so is the installation procedure.

First consider the length of tubing. You'll want to allow at least 12 inches of straight tubing before connecting it to fittings. For steam-trace tubing bundles, add enough length to connect the tracer to the supply connection and to the return connection. For electric-traced tubing bundles, add enough length to connect to the power supply. Include 6 inches for inside the junction box. Don't forget to include extra length to heat any other devices at the end of the bundle. Also, use the approved power connection and termination kits.

You'll want to use a centerline tool when you are bending tubing bundles to connect them to instrumentation. Start by cutting and removing the jacket and insulation on the tubing, so that you can see the process and tracer tubes. Insert the tube bundle through the seal boot in the tool, unscrew the center nut, and remove the center bend shoe. Now you'll be able to fully insert the tube bundle and gently bend the tubes against the outer shoes.

Install the center bend shoe and tighten the center nut. Bend the tubes against the center shoe until the tubes are parallel. Insert the tube bundle through the seal boot again, and remove the tubing bundle from the tool. To protect the insulation, seal the bundle ends with a heat shrink end seal boot.

Swagelok Flange Adapters Ease Transition from Pipe to Tubing

Posted by Katie Reid on Fri, Feb 19, 2016 @ 14:02 PM

Simplify the design and save weight compared with threaded branch connections


flange_adapter.png

Interested in more information on Swagelok's Flange Adapters? Download your copy of the Flange Adapter Catalogue.


When a fluid systems operator wants to get information such as pressure, temperature, and flow from a piping system, one common method is to use Thredolet® or Weldolet® branch connections. That strategy may get the job done, but the results can be complex and cumbersome. It's easy to wind up with a multitude of nipples, valves, and other threaded or welded components.

All that added weight is subject to vibrations from the process pipe, increasing the chance of a pipe break, resulting in potential for a dangerous gas leakage. Then production has to be shut down while someone makes repairs; this can make for a costly day at the office.

A better way

Swagelok's flange adapters and modular flanged valves make the job a lot easier. They provide a threadless, weldless transition from flanged pipe to tubing, reducing both the number of connections and the overall weight. They come in several configurations, including flat face, raised face RTJ and tongue-and-groove. They also have wrench flats to ease the assembly of tube fittings.

We were able to implement this type of solution recently for one of our customers, a large energy company that transports and distributes crude oil, natural gas, and other liquids. They had problems with a system of branch connections on a system under 1,440 psi, taking fluid from a process pipe to a pressure relief valve. The heavy assembly created intense vibration. Now, thanks to Swagelok, the customer has a simple, clean connection that takes up little space and doesn't add much weight to the system.

Does your fluid system need a simpler approach to branching off from your piping system? Let someone from our staff show you how to make it happen.

Building Up Swagelok's Inventory of Special Alloys

Posted by Katie Reid on Fri, Feb 12, 2016 @ 14:02 PM

We listened when customers wanted new materials, and they listen to our advice


It's a simple principal, but a powerful one: In order for us to serve our customers well, we need to understand the markets we serve. We need to understand our customer, and we need to understand the application.

Gerhard Schiroky, principal scientist for Swagelok Company, explains in a video how that has changed the kind of materials that Swagelok works with over the years. It is part of a video series produced by Swagelok Company featuring Swagelok executives speaking on topics ranging from quality, customer service, predictive maintenance, and more.

 

"If you go back many years, we were receiving many quote requests from customers for materials of construction which we did not have," Schiroky says. We started to track these requests, and we started to understand why customers were asking for these alloys. 

Over the years we have introduced different metals, including the Super Duplex stainless steel, which offers extra corrosion resistance. We've also introduced:

  • Alloy 400, a nickel-copper alloy. It offers exceptional resistance to hydrofluoric acid to stress corrosion cracking and pitting in most fresh and industrial waters.
  • Alloy 600, a nickel-chromium-iron alloy. This strong alloy is highly resistant to chloride-ion induced stress corrosion cracking.
  • Alloy 625, a nickel-chromium-molybdenum alloy with a small quantity of niobium. This combination provides very good resistance in a wide variety of severely corrosive environments, including hydrochloric and nitric acids.
  • Alloy 825, a nickel-iron-chromium-molybdenum alloy designed to resist general corrosion, pitting and crevice corrosion, as well as stress corrosion cracking in a wide range of media. Incoloy 825 stands up particularly well to sulfuric acid, phosphoric acid, sulfur-containing flue gases, sour gas, oil wells and seawater.
  • Titanium alloys. They have excellent resistance to corrosion in a wide variety of environments including seawater, salt brines, inorganic salts, bleaches, wet chlorine, alkaline solutions, oxidizing acids and organic acids.

If a customer needs an exotic alloy that's new to us, we're always willing to take a look at the request. "We can machine any of our fittings out of almost any material that is machinable," says Jason Wynne, a member of the sales and service team here at Edmonton Valve and Fitting.

But just stocking special alloys was not sufficient. Customers wanted to engage with us.

"They wanted us to recommend which alloy to use for specific applications," Schiroky. Because of their trust in us, "they have acted upon our advice. And I believe they have been very happy with that advice."

Customers Asked, Edmonton Valve Responded: the Steam Lance

Posted by Katie Reid on Fri, Feb 05, 2016 @ 13:02 PM

The original idea was good, but we keep finding ways to make it even better


steam_lance.png

The Steam Lance, pictured above, is an unique product that comes pre-assembled and ready to use & install at your site. For all the product's highlights and benefits, download the Steam Lance info sheet.


It started when a customer asked Swagelok for a new kind of product. It would be a device that could be hooked into a steam line and used to remove ice buildup on equipment without having to shut the system down. Workers in the field would not have to improvise a tool on the spot that may not meet safety standards and could cause preventable injuries.

The result was the Steam Lance. It consists of a piece of insulated tubing, heat-shrink boots to seal off the insulation, and a 60 series steam-rated ball valve at one end. It's an elegantly simple solution that's ready to use right out of the box. The customer can order it with a single part number and can operate it with confidence because it's 100 percent tested before it leaves our shop.

But wait, there's more

Now the scene shifts here to Edmonton. We liked the Steam Lance, and our customers did too.

"We use steam lances to clear plugged drain valves, clear plugged piping, and for melting ice hanging from outside structures," says one of our customers. "There really wasn't a good off-the-shelf solution that we were able to find. There were some steam-cleaning tools on the market, but they were heavy and awkward to use in tight areas. This particular Steam Lance, on the other hand, is the right weight and size for the job - and it is pressure rated.”

But we, as well as our customer, saw room for improvement. We added a 12-inch piece of insulated pipe upstream of the valve, giving the operator something to hold on to other than the steam hose itself. We also insulated the valve to further protect the operator.

The key reason for making these improvements was summarized by our customer when he said, “The safety piece was really important as several people had been burned while using home-built solutions.”

At Edmonton Valve & Fitting, we know steam, and we know how to deal with cold weather. Put us to work for you. Download a copy of the Steam Lance Information sheet.

What Topped Edmonton Valve's Customers' Reading Lists in 2015

Posted by Katie Dennis on Tue, Jan 12, 2016 @ 11:01 AM

These downloads drew the biggest audience in the past year


Swagelok_Edmonton-82.jpg

One of the most popular features of our website is the ability to download catalogues, manuals and other material. All it takes is a couple of clicks and a little bit of information so we know where to send it all. These are the downloads that proved most popular in 2015 - did you download them all?


Swagelok VCR and VCO fittings

Most people know Swagelok for our two-ferrule Tube Fitting. However, we also carry two valuable lines of face seal fittings: VCR and VCO. Unlike pipe, tube, and weld end connections, the VCR and VCO fittings can be disassembled in line – with no clearance requirements. VCRs and VCOs serve as a make and break point – a spot to access the system for repair and upgrades without having to remove multiple parts.

Tube bending manual

Bending tubing by hand is often the fastest and simplest way to get the job done. The Hand Tube Bender Manual explains step-by-step how to prepare, measure, and calculate, to perfectly execute the bends every time. This 32-page download covers bends, reverse bends, springback and other essentials, and has a section on troubleshooting.

Tube fitting manual

Swagelok hadn't revised its classic Tube Fitter's Manual since the 1990s, so it was a big deal when a fresh edition came out for 2015. The manual has been updated and expanded to include information on selecting tube fittings for severe service requirements, metallurgy, innovations in product design, and advanced manufacturing processes.

Swagelok quick-connects

Swagelok Quick-Connects offer a push-to-connect coupling that enables quick, easy operation. We offer a wide variety of options, including keyed quick-connects. The catalogue includes information on the four different Swagelok Quick-Connect series as well as drawings, sizes, materials, and end connections. It also lists all the part numbers for your convenience. Don't forget - the series of the stem and body has to match for them to connect!

Just ask EVF

You can't get a more personalized service than our Ask Edmonton Valve & Fitting page. Just tell us who you are, what you want to know, and where to send the answers. Whether you are starting to compare your options, need a tailored proposal, or just have a question, we're always here to help.
