Strength and Simplicity: Medium Pressure Fittings

Posted by Alecia Robinson on Tue, Aug 15, 2017 @ 14:08 PM

They handle extra pressure without requiring any extra tools or extra effort


Medium pressure fittings.jpg

When you need a robust fitting that can handle up to 20 000 psig with an easy installation, Swagelok medium pressure fittings are a great solution. Download the Medium- and High- Pressure Fittings Catalogue to find out more.


Earlier this year we wrote about Swagelok's IPT fittings for high-pressure applications. But maybe you are looking or something that takes less time to install and can be verified for proper installation. For pressures that don't go beyond 20,000 psig (1378 bar), consider Swagelok's line of medium-pressure fittings.

With our medium-pressure fittings, you don't need any special tools or special skills. You don't have to cut threads or cone the ends of the tubing, as you would for the high-pressure fittings.

The simple two-piece design of Swagelok's medium-pressure tube fittings and adapters consists of a female fitting body and preassembled cartridge containing the male nut and color-coded front and back ferrules on a disposable plastic arbor. The preassembled cartridge ensures that installers will have the correct ferrule orientation, plus visual confirmation when the ferrule is present and properly installed in the female body.

The components are released only after the nut is threaded finger-tight on the fitting body.

Key differences

While Swagelok's medium-pressure fittings don't require special tools or skills, their installation differs from standard Swagelok fittings in a few key areas. 

First, it takes only one full turn to pull up the fitting, not the turn-and-a-quarter of our standard fitting. Second, proper tightening can be measured by torque as well as with our gap-measuring gauge. Third, Swagelok's medium-pressure fittings are designed to industry standards rather than using a proprietary design. That means this is one of the very few components in the Swagelok catalog that can be mixed into your fluid system without having to upgrade all the fittings at once.

In our medium-pressure line we have straight fittings, 90-degree elbows, tees and union crosses, plus caps and plugs.

The strain-hardened stainless steel bodies offer lightweight space-saving designs. You'll also get Swagelok's patented low-temperature case hardening processing of the ferrules and nut.

Your fluid system needs to run on the right pressure for the job, and you need the right fittings for the pressure. Edmonton Valve & Fitting can make sure you get the right match. Call us at 780-437-0640 or contact us through our website.

ABSA and CRNs: We Have Your Parts Covered

Posted by Alecia Robinson on Wed, Aug 09, 2017 @ 10:08 AM

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


CRN Database.jpg

The Edmonton Valve MTR website not only hosts our extensive list of MTRs you can also search for CRN Statutory Declarations. Pictured above is the list of our statutory declarations on our self-serve website which can be found at edmontonvalve.com/mtrs.

GET IN TOUCH


If you have a fluid system running at more that 15 psi, you probably have heard of the Alberta Boiler Safety Association. ABSA 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. ABSA is also responsible for the certification of pressure welders, inspectors and power engineers for the operation of a power or heating boiler.

When you go over that 15-psi threshold, ABSA mandates that all the components must have Canadian Registration Numbers. That's one of the reasons why our customers can relax when they order Swagelok products. Swagelok has a team that proactively manages our CRNs and ensures that they are regularly reviewed and kept up to date. With hundreds of CRNs, this is no small task.  Our current project to renew all of our CRNs is a 4 year program, with year one set up for planning and then the product submissions staggered out of years 2, 3 and 4.

CRN and Statutory Declarations

CRNs and Statutory Declarations are issued by the province. The Statutory Declaration is the document issued upon acceptance of the CRN by ABSA in Alberta,  and other local authorities in the rest of Canada. We can provide Statutory Declarations at no charge and can be found on our MTR site at edmontonvalve.com/mtrs.

A typical Statutory Declaration will include a cover page and backing documents on the product lines covered, including pressure ranges and product catalogues.

Lunch and learn

While most reputable companies know the basics, a few common questions come up. A couple of times a year, Edmonton Valve & Fitting will bring someone in for a lunch-and-learn session to cover topics such as what to do when an ABSA inspector comes to a site.

The Advantages of Swagelok VCR and VCO Fittings

Posted by Alecia Robinson on Thu, Aug 03, 2017 @ 16:08 PM

Most people know Swagelok for our two-ferrule Tube Fitting. However, we also carry two valuable lines of face seal fittings.


VCR_zero_clearance1-1.png

VCR and VCO zero clearance allows for inline service. Download the VCR & VCO catalogue today for more information.


The VCR and VCO product lines are two more items that could save you a lot of time and money down the road. The primary distinguishing feature of the VCR and VCO fittings is that they have a zero clearance capability. This means that 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.

They also feature silver plating on all female threads, which prevents galling and eliminates the need for thread tape, which improves ease of installation. There are also leak test ports on the side of each nut, where the metal faces come into contact and the seal takes place. Lastly, there is a split-nut available, which further increases the ease of assembly and reassembly.

Easy access

Thanks to the flat face seal of both the VCOs and VCRs, you have unlimited make and remake capabilities. All you have to do is replace the gasket on the VCR  each time you remake the connection. The gasket is the least expensive piece of the assembly, so replacing this is much more cost effective than replacing the whole assembly. When installing the VCRs and VCOs, tighten the nut finger tight and then use a wrench to turn the nut 1/8 of a turn.

There are certain capabilities that differ between the two products. For example, in high temperature applications, the VCR  is a better option because the metal gaskets allow for a much higher temperature capability; as high as 1000 F for a stainless steel gasket.

Assembly options

VCO Assemblies:

Gland + Body + Nut

 VCR2

VCR Assemblies:

Female Nut + 2 Glands + Gasket + Body (Male Nut)

OR

Female Nut + Gland + Gasket + Body

 VCR3

 

Multiple applications

VCRs and VCOs are popular in hydraulic systems as well as welded and threaded systems. They also provide a great transition from such systems to a tubing system, by using a tube adapter end connection. Thanks to the variety in end connections that are available in VCRs and VCOs from Swagelok, there are endless combinations available to our customers. For more information on how VCR and VCO fittings could work for you, download the catalogues, or ask us.

A Seal of Quality: Take Care of Them to Save Money

Posted by Alecia Robinson on Thu, Jul 27, 2017 @ 08:07 AM

Our API compliant seal support systems help you get smoother operation for longer periods


Seal Support Systems-2.jpg

The Swagelok Seal Pot Fill Tube (pictured above far left and middle) and bucket pumps (right image) are just some of the solutions available to ensure proper functionality of the mechanical seal. For more information download Edmonton Valve's Seal Support Brochures.


The biggest single cause of pump failure is the mechanical seal, responsible for 39 percent of all failures. To keep pumps humming along, those seals need to be properly supported with the appropriate mechanical seal support system. Mechanical seal support systems keep seals clean and cool by flushing contaminants away. Plants and people are also kept safe by these systems preventing leakage to atmosphere through the delivery of barrier and buffer fluids.

What happens if equipment fails? What are the consequences of a leak or spill? What are the likely methods of failure? Keeping everything running smoothly is a hard job, involving in-the-field engineering. We want to help make it easier to keep seal systems running efficiently. Edmonton Valve and Fitting's seal support systems are fully assembled locally to meet the needs of our customers. These systems offer a reliable and high performance solution for your mechanical seals.

Fill tubes and bucket pumps

The traditional way of refilling seal pots has been to shut down the pump and wait for the equipment to cool. Once cool, personnel would use a ladder to climb and manually fill the seal pot from the top. This process, in addition to be being inefficient and time consuming, could expose workers to hot or hazardous vapors.

Consider instead a Swagelok Seal Pot Fill Tube. It's ideal for refilling seal pots for pumps with dual seals. Each seal pot has a fill tube that allows for a quick and safe refill. A simple ball and check valve assembly provides online refill, reducing costs and eliminating downtime. The operator can work from ground level and doesn't have to worry about exposure to vapors.

Another useful tool is a Bucket Pump assembly typically used by instrumentation technicians. This complete solution allows the technician to blow out plugged lines and components with water, glycerin, glycol, naphtha and other fluids.

We use a standard design with standard components but have the flexibility to customize your design right here in Edmonton.  

 

When you let Edmonton Valve & Filling help, you can devote fewer resources to maintenance and concentrate on other priorities. Ready to get started? Contact us through our website or by calling 780-437-0640.

Tagging Hoses at Edmonton Valve & Fitting

Posted by Adam Telenko on Thu, Jul 13, 2017 @ 16:07 PM

Tagging is a great way to make sure that vital information always stays with the component


Tag machine.jpg

Edmonton Valve's laser engraver can make quick work of your tagging needs. As tags are made in house it easy to customize them with the information you need.


Tagging in

You may be aware that Edmonton Valve & Fitting has been providing hose tags for years, but what may be new is how hose tags are being used in the field under Quality Assurance (QA) Programs throughout our service territory.

Hose maintenance programs are gaining momentum for several reasons:

  • Safety & Preventative Maintenance
  • Traceability
  • Identification
  • Tracking & Replacement scheduling
  • Ease of ordering

What type of information is typically captured on the hose tags? Hose type, CRN#, pressure test date, part number, hose ratings, pressure/temperature ratings, site location, vendor, system media – to name a few! 

At Edmonton Valve & Fitting, we are also populating database records for our customers who have adopted a hose maintenance program. These records are unique to each customer and completely customizable to reflect the program’s intentions.

Ask your Swagelok sales and service representative for more details on hose tag options and how we can help with a hose information database.

Swagelok Parts Help Keep Eco Car Competitive

Posted by Alecia Robinson on Wed, Jul 05, 2017 @ 13:07 PM

University of Alberta students get hands-on education in international competition


EcoCar blog photo.jpg

The University of Alberta's EcoCar Team knew that in order to compete in the 2017 Shell Eco-Marathon Americas they needed leak-free parts, which is why they turned to Swagelok. Do you need our help with a project, get in touch today to see how we can help.

GET IN TOUCH


Long known for its importance in the oil and gas industry, Edmonton is also getting some attention in the world of alternative fuels for transportation. A team of students from the University of Alberta is making some fast progress with using fuel cells in cars.

The EcoCar Team is a student-run engineering organization that designs and builds prototype vehicles powered by hydrogen fuel cells. The team primarily races at the annual Shell Eco-Marathon Americas, held in Detroit. The marathon has different classes of competition based on how the vehicle is powered: fuel cell, solar cell, gasoline, diesel, and liquefied petroleum gas. Cars must average at least 24 km/h over a distance of 16 km.

The University of Alberta team placed second in its category in 2012, the team's first year of competition, and came in first in 2014. The second-generation vehicle took two years to build and captured another first in 2016. Technical glitches hampered performance in this year's Eco-Marathon, but the team still took home $2,000 for a second-place place finish. 

Where we fit in

We first encountered the students this past February when they came to us for some fittings and other miscellaneous components. Student-led projects don't get much funding, so we were glad to donate the parts, and get them quickly so that work could stay on schedule. In return for the favor, they put the Edmonton Valve & Fitting logo on the EcoCar.

Each prototype starts from scratch.

"I saw it at the beginning stages, and it didn't really look like much, and then I saw it at the end. It was pretty neat to see the finished product," says Andrew Worthington, one of our account managers. "It's high intensity work, 30 to 50 hours a week on top of classes. It's essentially a second full-time job."

The project brings together several academic disciplines, so the students get an opportunity to use their education in a real-world application.

Before Shell will let any competitors on the test track, each car must pass an inspection. If there are any leaks from the fuel cell, the car won't get the green light. Thanks to the Swagelok parts, that was no problem this year.

 

Do you have a project that needs to roll out leak-free and on time? Edmonton Valve & Fitting has the components and the expertise to get you there. It's easy to start the discussion through our website or by calling 780-437-0640.

Meet Derek Green

Posted by Alecia Robinson on Fri, Jun 30, 2017 @ 08:06 AM

Our Custom Solutions Operations Coordinator keeps your special project on track


Derek CS (1 of 1).jpg

Derek Green, pictured above, has been a vital part of Edmonton Valve team over the years. If you've got questions about our Custom Solutions capabilities, give Derek a call or follow the link below.

Custom Solutions


On our seven-person Custom Solutions team, Derek Green has a lot to do with keeping a project on track. He's likely to be the one scheduling your project and making sure we have all the parts on hand to assemble it quickly.

There's no such thing as a typical workday for Green. Custom Solutions covers a wide range of projects, from something as simple as putting the identical bend in a hundred pieces of tubing to creating a complex sub-assembly with panels, valves, gauges and special fittings. Green spends a lot of time figuring out price quotes. Sometimes customers present a complete idea of what they want, and sometimes we have to start with a more general concept. It sometimes takes a few attempts to nail down exactly what the finished product should include. We make sure the details are all on file in case you ever need us to duplicate the job in the future.

When Green is figuring out the logistics of getting the parts here, the vast majority will come from Swagelok. But there are times when other manufacturers are involved as well, so we count on him to track down the vital parts.

Careful start

Green has been with us for about four years. He already had some experience in fluid systems, but more in the areas of industrial pipe and flanges. So while he served many of the same customers he works with now, he had to learn about Swagelok products and the way Edmonton Valve & Fitting operates.

We wanted to know how Green operates too. Like most of our associates, he had to go through a long process of multiple interviews before we knew we wanted to offer him the job.

"They search for a good fit. They do things right," Green says. "They just seem to care about their employees. If someone is having an issue they get to the root cause and come up with a solution that works for you and them."

We know that a person who fits in well can stay with use for decades that’s why we pay attention to where our associates want to take their careers, and give them training to help them get there.

Green's training started where so many people start: in our warehouse. There's nothing like picking parts for a few months to help a person get familiar with the Swagelok inventory. From there he moved into customer service, then to outsourcing non-Swagelok parts.

Along the way he earned a diploma in Supply Chain Management from the University of Alberta, as well as his PMP designation as a Project Manager.

The combination of experience and education made Green a good candidate when we had an opening in Custom Solutions. It also makes him a good person to talk to when you want to find out how our expertise can make your life easier. Call us at 780-437-0640 or contact us through our website to find out.

Swagelok Services Relieve the Other Kind of Pressure

Posted by Alecia Robinson on Tue, Jun 20, 2017 @ 09:06 AM

Knowing how to troubleshoot your fluid system reduces expensive downtime


 

At Edmonton Valve we have the resources to help you design effective sampling systems. From hands-on training and Evaluation and Advisory Services, our experienced experts are here to help you. Watch this video highlighting some of the ways Swagelok can help you.


Some kinds of pressure are good, like maintaining reliable pressure in a fluid system. Other kinds of pressure are bad, like the kind you feel when your fluid system isn't working as it should.

You already know that Swagelok components are great for dealing with the first kind of pressure. But Edmonton Valve & Fitting can also help with the second kind with our training, education, evaluation and advisory services.

Take a few minutes to look at this short video (which just happens to include an appearance from our own field engineer Stacey Phillips), and you'll learn a little about what we can do for you.

Pressures mount

As Phillips says, customers today are under more pressure than ever from increasing safety regulations and pressure to make more profits. At the same time, a lifetime of knowledge walks out the door each time a longtime worker retires.

That's where our training classes can add a lot of value. We make sure that your engineers, buyers and installers understand that good design, operation and maintenance goes way beyond "I just need a valve." When your installers are properly trained on tube fitting safety, you'll have fewer leaks. When your trained technician is troubleshooting, they'll recognize the symptoms and quickly narrow down the areas that require attention.

If you need more expertise than you have on site, we can come out and look over your fluid system. We can do the troubleshooting, but we also can help you evaluate some of the things that might need to be done to improve the system. When you have a well-designed system, you get better reliability, and your maintenance crew isn't tied up dealing with day-to-day problems.

An increase in throughput means an increase in productivity, which translates to an increase in profitability.

 

Edmonton Valve & Fitting offers so much more than components. We have expertise to share. Tap into it by calling us at 780-437-0640 or contacting us through our website

Keep Your Sampling Systems At Peak Performance

Posted by Alecia Robinson on Thu, Jun 08, 2017 @ 14:06 PM

Our two-day Sample System Maintenance Course will cover operations and troubleshooting


SteamSystems.jpg

Teaching you to trouble shoot a variety of common sampling system issues, from the process line through sample disposal. Join this two-day course on November 14th and 15th, 2017, sign up now to attend.


Your analytical instrumentation system can't give reliable results unless you give it a reliable sample of the fluid in your process line. Assuming the sample is properly taken at the tap, it may fall victim to a host of problems:

  • Deadlegs or dead spaces that create a “static leak,” where fluid from an old sample might bleed or leak into the new sample
  • Contamination, permeation, or adsorption
  • A phase change that upsets the balance of chemicals
  • A chemical reaction

The most common cause of inappropriate response is a simple delay. If it's taking more than one minute from tap to analyzer, you may have problems.

How can you work to prevent problems and fix those that do appear? Take our two-day Sample System Maintenance Course.  We've scheduled it for November 14 and 15 at our brand new training center.

The basics and more

Leading the course this year is Swagelok expert Stephen Jacobs, owner and president of Jacobs Process Analytics Inc. Over more than 25 years he has designed, installed and maintained hundreds of analyzer and sampling systems for applications ranging from safety monitoring to closed-loop process control.

We start out by reviewing sampling basics: Why you take samples and how to take them properly.

Sampling systems come in a variety of designs, especially when you compare those designed to handle liquids and those designed to handle gas. We will look at all types of systems, the typical best practices and the typical mistakes that people make. That starts with the system design itself, making sure that it uses the proper size of tubing, proper filters and other components.

The goal is to send you back to your company with enough knowledge to walk through your systems and spot problem areas.

You'll spend time taking lecture notes, but you'll also get your hands on the equipment. We'll put students into groups and give them some problems to solve from real-life case studies. We'll explain the issue, and then it will be up to the teams to discover the cause and come up with a solution. Each group will then present its project to the rest of the class. 

Lunch too

We'll provide all the materials you need, including a workbook you can take home with you. Those who pass the course also will go home with a certificate of completion. We'll even serve you lunch on both days.

But we have a limited number of seats. That's why we're letting you know so far in advance. Mark your calendar now and sign up today.

Compact and Able to Handle Heat: The VB0451 Valve

Posted by Alecia Robinson on Fri, Jun 02, 2017 @ 08:06 AM

Here's a new addition to our line of space-saving process interface valves


VB0451.png

The latest addition to our double block and bleed lineup is the VB0451, pictured above. This metal-seated process interface valve allows for an extended temperature range and greater resistance to particulate containing liquids.

Block & Bleed Download


Over the years we've written about some of our space-saving process interface valves, from the VB03 and VB04 for ordinary service, to the VN01 for severe service.

There's one more member of the family worth mentioning, because it's a new addition to our inventory in the past year: the VB0451. It's a metal-seated process interface valve that offers an extended temperature range and greater resistance to particulate-containing liquids than standard process interface valves.

As with all of our process interface valves, the VB0451's compact size and reduced weight means that it takes up less space and requires less support structure. Because it's a single-valve unit, you can install it faster than the more traditional three-valve assembly for the same job. Having a single unit also means fewer leak points and less required maintenance.

Taking the heat

Beyond the basics, though, the VB04051 can stand up to high temperatures. Where the VB04 is rated up to only 204ºC, the VB0451 can handle temperatures up to 310ºC, and up to 280°C for duplex valve assemblies.

Swagelok tests every metal-seated process interface valve hydrostatically at the factory to a requirement of no visible leakage. A shell test is performed at 1.5 times maximum rated working pressure, and a seat test is performed at 1.1 times maximum rated working pressure. These valves are tough.

Swagelok also performs a low-pressure gas seat test, and fugitive emission testing is available on request. Metal-seated process interface valves for sour gas service are available as well.

Other features

The VB0451 valve features double block-and-bleed design in a compact ball/needle/ball configuration. The one-piece forged body is available in carbon steel, 316 stainless steel or Duplex stainless steel.

The process connections can be from half-inch to two-inch flanges, and the outlet valve is available as a flange or a half-inch female NPT connection.

A lockable handle is standard.

If you'd like to learn more, call Edmonton Valve & Fitting at 780-437-0640 or contact us through our website, and we'll be glad to answer your questions.
