Hoses can manage an abundance of applications because of the wide variety of available materials and configurations. Download Swagelok's "Be Flexible - Hose is the Best Choice for Many Power Applications" PDF below.

Hose in Power PDF


Flexible hose may be one of the most under-used components in a power plant. With the latest advances in hose technology, you can use hose in many places historically limited to tubing or pipe.

Swagelok hose is available in custom lengths up to 100 feet, in diameters 2 inches and under, and with a wide variety of end connections. With the proper selection of material options, hoses are completely dependable across a wide range of pressures and temperatures.

The principal benefit of hose is easy installation and easy replacement of adjoining components like valves. It’s just a lot easier to work with hose than with rigid tubing or hard pipe because there is no bending, welding, or fitting. As a result, you will save a lot on labour costs.

Hose is an excellent choice for these common applications in a power plant:

  • Compressed and instrument air applications
  • Connections to compressors, pumps, or other devices that cause vibration
  • Connections to pneumatic actuators on large control valves
  • Chemical tote offloading equipment
  • Hydraulic and lube oil applications subject to vibration
  • Pressurized gas delivery from tanks and cylinders
  • Sample analysis systems that draw fluid from process lines
  • Natural gas, diesel, or liquid fuel handling applications

What's in a hose?

Typically, hoses consist of a core, reinforcement, covers, and end connections. Core materials may be metal, fluoropolymer, thermoplastic, or rubber. Many power plant applications employ stainless steel cores, which offer corrosion resistance and high-temperature compatibility – up to 850˚F (454˚C).

Reinforcement layers – often stainless steel woven braid – improve pressure containment and flexibility. With stainless steel braid, hoses available from Swagelok can manage pressures up to 6000 psi!

In power plants, a silicone cover is often added in high-temperature applications to greatly reduce the likelihood of burns on contact.

Hoses can be fitted to a wide range of end connections, including tube adapters, tube fittings, VCR metal gasket face seal fittings, VCO O-ring face seal fittings, swivel fittings, NPT pipe threads, pre-swaged nuts and ferrules, tube butt welds, flanges, Kwik-Clamps, cam and groove, tube stubs, and more.

When to use a hose?

In a power plant there are many places where hose pays for itself very quickly:

• Connections Requiring Complex Tube Bending. Tube bending is not difficult, but it does require some tools and training. If your technicians do not have tube-bending skills, consider hose. Sometimes a replacement part does not have the same dimensions as the original, and the original section of tubing or pipe does not quite align with the new connections. You can sidestep a difficult or frustrating situation like this with hose.

• Applications with Severe Vibration. Hose can manage vibration stress better than tubing, especially when high pressures are in play. In a high-vibration application, a run of hose can dampen vibration between the source and the rest of the tubing assembly. It's important to note that not all hoses are suited for high vibration, so correct selection is critical. An Edmonton Valve hose specialist can help you select the right hose based on your application.

• Temporary Connections. Hose is an excellent choice for water sampling, chemical sampling for analysis, or for offloading chemicals from totes. It bypasses alignment issues associated with rigid pipe or tubing, and it can attach with a cam-lock or quick-connect.

• Moving Parts. Pneumatic actuators on some large control valves move up and down and therefore require a flexible connection to the compressed air source. There are many other such applications where you need to allow for some movement or flexing, and hose is your best or only choice.

• Parts Requiring Frequent Replacement or Servicing. In applications requiring frequent maintenance, tubing or hose may be appropriate, depending on the circumstances. Both can connect by way of Swagelok tube fittings, which can be disassembled and reassembled with the turn of a wrench. Gas turbine inspections, for example, require frequent assembly and reassembly of components. Metal hose makes this easier, enabling quick access for maintenance personnel.

We have an illustrated PDF brochure with more detail on how hose can enhance your performance and reduce maintenance. Or if you have any further questions about fluid systems, call Edmonton Valve and Fitting at 780-437-0640 or contact us by clicking the "Message Us" below.

Comprehensive training in tube fitting installation with Swagelok's Total Support Training Seminar


Goggles

To learn more about our Swagelok training classes, download a copy of our free training catalogue and find the class that suits your team's development.

Training & Education


In 2018 we trained approx. 249 students in our Swagelok Total Support Training (STS) full-day course, and the year isn't over yet! Plus that doesn't include all of the students that participated in our "mini" training sessions held off-site at customer locations. 

This STS seminar emphasizes the importance of choosing the correct tubing and fittings for your specific job, along with training on the proper handling, preparing, and installation of those components. 

Theoretical vs. practical 

The ISO certified class is broken down into two sections, first theoretical and then practical. In the theoretical portion there are seven lessons that breakdown the history of the tube fitting, installation procedures, leakage, the dangers of intermixing and interchanging parts, installation tools, and more. 

The practical portion allows the students to get hands-on with a tubing system where they demonstrate bending and proper tube fitting installation techniques. One of the more exciting parts of this section is where students install both an end cap and reducing union on a piece of stainless steel tubing and put it in our 'burst chamber' to test how well it performs under pressure. 

What's included

The full-day course comes complete with a comprehensive work book, installer pocket guide, tube bender manual, inspection gauge, gripper pad, and marking device. Morning snacks and lunch will also be provided. After successful completion of the course the attendee will receive a certificate of completion (valid for 36 months).

Q&A: Swagelok Tube Fitting Pressure Ratings

Tue, Aug 07, 2018 @ 09:08 AM / by Katie Reid posted in Fittings, Q&A

0 Comments

Customers often ask us about how to find out the pressure rating of a particular Swagelok tube fitting. Here's how our team provides the answer.

 Q1: What is the lowest-rated component in the system?

The pressure rating of a Swagelok tube fitting depends on the lowest rated component in the system in which it is installed.

Sometimes the lowest pressure rated component is a pipe thread, a pressure gauge, or a valve. Other times it will be the pressure rating of the tubing itself, and that will vary depending on the tubing's size, wall thickness and material of construction.  

Q2: Is the tubing softer than the fitting material?

Swagelok provides tables with the suggested allowable working pressure and suggested ordering information for tubing to be used with Swagelok tube fittings.

The key to selecting proper tubing for use with metal Swagelok tube fittings is that the tubing must be softer than the fitting material. Swagelok tube fittings are designed to work properly with the tubing that is suggested in the ordering instructions.

The tables show working pressure ratings of tubing in a wide range of tube wall thicknesses and outside diameters. Swagelok tube fittings have been repeatedly tested in both the minimum and maximum wall thicknesses shown in the tubing data tables. Swagelok tube fittings are not recommended for tube wall thicknesses outside the ranges shown in the tables for each size.

3. How will it be installed?

System performance also depends on correctly installing your Swagelok tube fitting. Check out this clip to see the kind of tube fitting installation training available in our seminars:

Brush up on fabricating, choosing tubing vs. pipe, applying thread sealants and lubricants, and more with experienced, Swagelok-certified trainers, and earn a signed Swagelok Certificate of Completion.

Edmonton Valve's Travelling Grab Sample System Demo Panel

Thu, Jul 26, 2018 @ 12:07 PM / by Katie Reid posted in Fittings, Valves, Q&A, Custom Solutions, Sample Systems

0 Comments

If you can’t make it to our office, we can come to you with our new Grab Sample panel*


Grab Sample Blue ll

This past June we featured our new Grab Sample System demo panel, outfitted with clear tubing components and a clear cylinder. Interested in seeing a demo for yourself, send us an email and we can make that happen!*

Contact Us


There’s no better way to see how something works than to see it live in action. That’s why we have built a Grab Sample System Panel with clear components, so you can see the fluid running through it and get a better perception of how it all comes together.

“Behind the scenes” look

We first showcased this Grab Sample panel in our Swagelok booth at the Global Petroleum Show in Calgary this past June.What makes this panel unique is that we used clear components (tubing and sample cylinder) and ‘Swagelok Blue’ water running through the system. This gave those watching a detailed look at how the fluid moves through the system and fills up the cylinder as the sample.

“Seeing the fluid run through the system with the clear components was really cool and it gave me an unobstructed view of how this product works,” says one customer visiting our booth. “It was also great that I was able to get a description from the Swagelok account manager on what was happening in real time and answer my questions right on the spot.”

New to this system?

If you weren’t able to make it down to see the Grab Sample demo panel during the show and maybe aren’t too sure what the system is all about, here is a breakdown of what Grab Sampling can help validate:

  • Process conditions
  • The end product meets quality specifications
  • The online analyzers are ‘fit for use’
  • Quality of product during custody transfer

We also have a great resource page that goes into more details on Grab Sample Systems, with information ranging from covering the basics to system designs, and accessories. Access that information here.

Coming to you

Getting a live demo can really showcase what our Grab Sampling Systems are all about and we have our Grab Sample System set-up in our Edmonton office to do just that.  We will provide demonstrations to you and your staff, plus answer all your questions that you may have. Can’t make into our office? No problem. We can coordinate with your account manager to visit your location with the demo panel and give you that one-on-one time at your own leisure. Just give us a call or send us an email and we will get it set-up.

If you have questions or concerns, don't hesitate to call one of our experienced reps for further advice. Please click here to get in touch.

*Note: Grab Sample Panel visits can only be set-up in our Sales & Services area but we would be happy to get you connected to your local Swagelok distributor - so still send us your request!

Breaking Down the Facts on Why You Should Never Interchange Swagelok Components

Thu, Jul 19, 2018 @ 14:07 PM / by Adam Telenko posted in Fittings, Valves, Q&A

0 Comments

We take a closer look at the dangers of “interchanging” Swagelok components and how it can impact the performance of the parts.


fittings cluster

Swagelok fittings should never be interchanged or intermixed with parts from a different manufacturer as this will lead to voiding of the Swagelok warranty and other major risks to the components themselves.. 

Contact Us


With a seemingly endless number of tube fitting manufacturers on the market, we are often asked about the practice of “Interchange” or “Inter-mixing”. This practice is summarized as removing at least 1 component from a Swagelok tube fitting, and replacing the component(s) with those from a different manufacturer.

Is this a safe practice? Will the fittings perform to satisfactory standards? Who is liable if something goes wrong? What are you trying to achieve by ‘inter-mixing’ components?

These are all great questions! Let’s look at some of the issues involved:

  • CRN (Canadian Registration Number) deemed VOID if intermixing components
  • There is NO Commercial Design Standard for tube fittings
  • Swagelok has over 200 active patents for our proprietary design
  • Swagelok Warranty applies to Swagelok fittings only – intermixing voids any and all warranty
  • End Users absorb full liability if inter-mixing fittings
  • Field data clearly shows inter-mixed fittings carry the highest leak %

Swagelok policy

Over the years, we have become aware of many manufacturers with products, which purport to be interchangeable and intermixable with Swagelok-designed products. We do not believe that any manufacturer can reliably, repeatedly and uniformly replicate the products of another manufacturer. For this reason, we believe that interchanging and intermixing component parts made by different manufacturers can result in unpredictable performance and increased costs. We believe also that this is an unsound practice and can be dangerous in critical applications.

3rd-party opinion statements

  • “It is certainly not ABSA’s position to suggest that it is alright to inter-mix components from different manufacturers….. The user of such a hybrid would be assuming a significant safety liability, in addition to contravening the (Safety Codes) Act.” TSSA (Canada) memo ABSA (Alberta Boiler Safety Authority), a branch of TSSA (Technical Standards & Safety Authority)
  • “Experimental tests and finite element analysis has shown that the swaging and sealing mechanisms of fittings are different despite seeing geometric similarities. It was evident that no two companies produced components to the same dimensional or metallurgical specification and that pressure testing alone should not be used as the only means of validation." Intermixing Twin Ferrule Tube Fittings-Is it Safe?  Journal of Engineering Design, Mihsein and Seymour Vol. 10, No. 4, 1999

Not worth the risk

With the information above, an inter-mixed ‘hybrid’ fitting does not retain a CRN#, possesses a high likelihood of leaking or catastrophic failure, and does not carry a warranty. In other words, inter-change opens up users to high levels of risk in various aspects. Keep your Swagelok fittings in-tact and experience the benefit of our over 70 years of manufacturing the highest quality tube fitting components in the industry.

We Have The Tools You Need For Cone & Thread Fittings

Thu, Mar 29, 2018 @ 16:03 PM / by Katie Reid posted in Fittings, Equipment Rentals, Tubing

0 Comments

Rent our manual tool to use on site, or have us use our automatic tool


Cone and thread tubing and tube niples

The equation for a High pressure working environment = stronger fitting + stronger tubing. But those tube bends can't be done with your hand tube-bender, so contact us to get those bends looked after. 


Longtime readers of our blog might recall a post about our IPT fittings for high-pressure applications. These extra-strong fittings are designed to handle pressures up to 60,000 psig or 4134 bar.

Just as high pressure demands a stronger fitting than usual, so does it demand stronger tubing. The special cold-drawn tubing for IPT fittings is harder and has thicker walls than our standard tubing. The threads must be cut into the ends, and finished off with a cone at a 59-degree angle. It fits into the primary seal surface of the fitting, which has a 60-degree angle. The tube walls are thick to that material can be cut away for the threads. In a sense it's really a very small pipe

It's tool time

So how to you get the threads and cone on the end of the tubing? We offer two options. You can rent a tap-and-die set from us, along with our bench-top tube bender. (Our handheld bender won't be up to the job for this thicker tubing.)

But if you prefer, we can do the work for you at our shop so that you save time and effort in the field. Our automatic tools in our own shop can easily perform work that is much harder to do on site. We can produce as many pieces of tubing as you need, and can even do things such as put a 90-degree nipple on the tubing.

Even if you are an old hand at tube bending, the harder steel and thicker walls mean slightly different rules. The bend radius must be larger, at least 1.25 inches for quarter-inch tubing.

These cone-and-thread fittings are designed specifically for the oil and gas, chemical, petrochemical, alternative fuel, and instrumentation industries. We'll be glad to tell you more and talk about your specific needs. All it takes to start the conversation is a call to Edmonton Valve at 780-437-0640, or a quick note through our website.

Calipers, Combs, And Guides Help Make Sense of Threads

Thu, Nov 09, 2017 @ 12:11 PM / by Alecia Robinson posted in Valves, Fittings, Measurement Devices

0 Comments

Scratching your head about threads? We have three tools that solve the mystery

  Tube_sizes_board.png
  The Pipe and Tube Sizes board (pictured above) is at our back counter. Bring in your fittings and we can help determine the sizing.
  thread_tool.png
  The thread pitch gauge is another tool we use to help with thread size - it's even available for purchase! To get more info on sizing, download the Thread and End Connection ID Guide PDF.

Can you tell the thread size and thread pitch on a component just by looking at it? Neither can we. That's why we have tools that eliminate the guesswork.

When you look at a thread, you'll see peaks (called crests) and valleys (called roots). The part in between the crest and the root is called the flank. The first thing you want to find out is whether the crests are all the same diameter. That would mean you have straight threads. So we get out our calipers and measure the first, fourth and last crests. If the measurements are the same, you have straight threads. If you get three different measurements, you have tapered threads.

There's another way to tell, provided that you are working with Swagelok parts. Other than standard NPT, Swagelok fittings are uniquely marked to indicate ISO tapered or ISO parallel threads.

Some people are surprised to learn that straight threads are not designed to seal on their own. They require a gasket, O-ring or some kind of metal-to-metal contact to finish the job.

Tapered threads are designed to seal as the mating threads are drawn together. In addition, some kind of sealant is necessary to prevent leaks. That's usually PTFE tape or a product such as SWAK.

Here comes the "pitch"

Next you need to know how close together the crests are. That's the pitch, usually expressed as the number of threads per inch.

Straight threads come in three standard kinds of measurements. The most common are SAE (Society of Automotive Engineers), ISO 228/1 (also known as British Standard Pipe Parallel), and metric. Tapered threads also have several standard forms of measurement: NPT (National Pipe Thread), ISO 7/1 (also known as British Standard Pipe), and metric.

The flanks can come in different angles, known as Whitworth, unified, or metric.

To discover the pitch, we use a thread comb, also known as a pitch gauge. It looks a bit like a pocketknife, but the blades have saw-tooth edges that fit into the thread roots. We simply try different blades until we find an exact match. Some fractional and metric thread forms are very similar, so we take the time to make sure it's a true fit.

You also can turn to the Swagelok Thread and End Connection Identification Guide, which you can download for free. It has all the terminology, thread ID reference tables, and step-by-step instructions for identifying threads.

Lastly, Edmonton Valve & Fitting has a board with various sizes of threads. If you come in with a part, we can see which sample it fits.

Obviously, the threads on two parts have to have the same size and type of threads if you want to connect them. But you don't have to guess. Check in with Edmonton Valve & Fitting and we'll work with you to get the right answer. Give us a call at 780.437.0640 or get in touch below.

Special Swagelok flange adapter with pre-drilled orifice simplifies design


Flange.Adapters.jpg

Threaded connections can be problematic when dealing with rotating equipment. Swagelok offers orifice flanges to reduce the number of threaded connections within your flush systems. Get in touch with us today to learn more.

Get In Touch


Sometimes a small modification can make a big difference in a fluid system component. Take, for instance, Swagelok's flange adapters. We've written about them before, explaining how they provide a threadless, weldless transition from flanged pipe to tubing.

We have a special flange adapter made with flush systems in mind. For our customers with rotating equipment, we offer the Swagelok orifice union and orifice flange adapters. Because the orifice is pre-drilled into the flange, between the tube fitting and the flange itself, you get a unique solution that helps reduce the number of threaded connections in your flush systems. You no longer need to worry about threaded adapters leaking due to vibration or freeze-thaw cycles. You'll also save money by not having to weld the flange.

As with all our flange adapters, they reduce both the number of connections and the overall weight.

Typically the orifice is drilled out to 1/8 inch, but we can supply custom sizes too.

If you are already using flanges to simplify your system design, reduce weight and end up with fewer leak points, you already understand the value of these flange adapters for flush systems in rotary equipment. If you haven't yet made the switch to flange adapters, we can help you get started. All it takes is a call to 780-437-0640, or you can contact us through our website.

What Are Swagelok's PFA Fittings All About?

Wed, Oct 25, 2017 @ 09:10 AM / by Adam Telenko posted in Fittings, Hoses, Valves, Tubing

0 Comments


PFA 1.jpgpfa 2.jpg

We have a full line of PFA fittings, valves, and tubing, to get your copy of these catalogues download them below.

PFA Catalogues


Swagelok carries a variety of materials for our fittings and tubing so selecting the correct one for the job can be daunting. We discussed some of the options in our blog on special alloys earlier this year but today we will further explore our PFA line of tubing and fittings.

PFA, or Perfluoroalkoxy, is a type of fluoropolymer. It has very similar properties as the more common polytetrafluoroethylene (PTFE) – also called Teflon.

PFA is generally used for plastic lab equipment because of its optical transparency, overall flexibility, and extreme resistance to chemical attack. PFA is also often used as tubing for handling critical or highly corrosive processes.

What to consider

You can use Teflon or metal fittings with Swagelok PFA tubing. Just remember using PFA fittings with PFA tubing you need to use a Swagelok groove cutting tool to 'groove' the tubing and achieve higher working pressures.

Some other important things to consider when selecting PFA tubing and fittings are the following:
  • An audible ‘click’ sound ensures tubing is properly inserted
  • 316 SS fittings can be used with PFA tubing
  • PFA Plug and Needle valves are available 

How to order

PFA part numbers are slightly different than Swagelok’s common tube fittings, for example:

  • PFA-420-1-4 for a 1/4" male connector
  • PFA-820-6 for a 1/2” tube union

But don't worry about memorizing part numbers, give your local Swagelok experts a call and we will be glad to help out.
