Did you know Edmonton Valve builds tube-in-tube coils (examples below) in sizes up to one inch tubing, in a wide variety of materials? And that our team is standing by help with all the flow, temp, and other necessary calculations?
Examples of tube-in-tube systems we can locally fabricate. For details please get our new Comparing Tube-in-Tube Systems Resource Collection:
The offering grew out of noticing a pattern in customer needs. Many customers have coils that were provided as part of an initial instrumentation package on their boilers. And most facilities have multiple generators.
It's common for them to have a preventative maintenance program that calls for replacing coils, say, every couple of years. So customers asked us, "is there another option besides these pre-packaged coolers?'" And the answer is "yes".
Swagelok coils complement pre-packaged options
In SAGD environments with steam generator constraints, in particular, customers benefit from having a range of cooler options.
When we talk with you about the design, we'll ask about your flow rate, your sample pressure, your sample temperature, your cooling media, and more. Once we know these details we can start to look at the options be it a tube-in-tube coil fabricated here in Edmonton or be it a Sentry prepackaged cooler.
The overall goal is to make sure that as that sample gets to either the analyzer or to the sample bottle that it's safe for the equipment and for personnel. Yet our customers operate in some of the harshest conditions on earth.
Built tough for challenging fluid, higher flows, longer service
Our systems tend to be able to handle challenging fluid, have higher flow, and cost less than pre-packaged options. Also our systems tend to be available in a broader range of materials, and we can fabricate locally. Through our Field Advisory Services we can help with your temperature calculations and the flow calculations, as well to ensure what's delivered is exactly what you need for your application. And it's also a bit easier to replace when necessary.
We are highly responsive, and we are local. Often we can turn these tube-in-tube systems a little quicker and at a lower price than you'll get with pre-packaged systems.
Safe sampling operations
Grab sampling is essential for validating process conditions, showing the end products meet quality specifications, ensuring online analyzers are fit for use, and tracking product quality through custody transfers. It can also provide verification of environmental emissions.
In all of these cases, capturing a representative sample is essential. But many processes operate at high temperatures, which means risk of operators being scalded and risk of exceeding the temperature limits of seats and seals. Swagelok recommends consideration of a sample cooler at supply temperatures above 140°F (60°C).
We see high supply temperatures in a range of oil & gas, power, chemical refining, and semiconductor applications. And in SAGD environments, the challenge is compounded by steam generator constraints.
Our Field Advisory Services team can help you determine the size and heat transfer for your coil design and make other key choices. Then we can build, test, and deliver your cooler ready to install and commission.
Exotic materials, special flow configurations, and more
The standard configuration of our tube-in-tube systems is a helical coil. But many other configurations are available. Indeed, we can meet a wide range of needs with respect to design, radius, tube sizes, end connections, materials of construction, and pressure ratings. We offer 316L stainless steel, carbon steel, special alloy tubing such as inconel and monel, and other exotic materials.
All components used in the construction of our tube-in-tube systems have Canadian Registration Numbers (CRN's), as well as a letter of compliance, materials test reports (MTR's), and other documentation. Each assembly is built in accordance with the Alberta Boilers Safety Association (ABSA) Certificate of Authorization Permit. And Swagelok products are backed by The Swagelok Limited Lifetime Warranty.
