Why Specify Swagelok Measurement Devices?

Why do engineers specify Swagelok devices? Because using other brands risks unpredictable quality, frequent maintenance, and safety hazards. Here are examples of Swagelok's thoughtful designs:

Minimizing Component Installation Errors

We train those who develop, install, inspect, maintain, operate, or buy parts for fluid systems.

We guide engineers, installers, technicians, procurement specialists, and quality managers in techniques for designing, implementing, and maintaining reliable, cost-effective fluid systems. Every seminar is led by one or more Swagelok-certified Trainers and some offer a Swagelok Certificate of Completion. Tube Fitting Essentials, FK Essentials, and Inspection Essentials are three examples of the seminars we offer.

Frequently Asked Questions

Is there a right/wrong way to use gauges?

Following 5 rules will help make sure you're using gauges correctly:

  1. Double gauge pressure over system pressure.
  2. Liquid fill where vibration is present.
  3. Always use a restrictor when pressure spikes are present.
  4. Hang a gauge upside down when high pressures and flows are present
  5. Never mount the gauge directly above a high temperature source

Each of these rules is explained in our article The Five Laws of Swagelok Gauges.

What is an instrumentation toolkit?

Swagelok's Instrumentation Tool Kit has all you need to assemble 3 sizes of Swagelok tube fittings: 1/4 inch, 3/8 inch & 1/2 inch. This includes hand tube benders, deburring tool, tube cutter, ratchet wrenches, pre-swaging tools, inspection gauge, tee wrenches, and the Swagelok Tube Fitter's Manual.

This kit keeps your tools safe, both in the travel to and from job sites, and safe from other elements in your surroundings. If you want to learn more, send us a note and we would be happy to get you started. 

See an example and learn more in our article Stay Organized with Edmonton Valve's Instrumentation Tool Kit.

When do we need a Swagelok area flowmeter?

Even for some of the simple applications -- you want a precise measurement. The most basic measurement device is the variable area flowmeter. It measures the flow rate of liquids and gases by means of a tapered tube and float. The float is pushed up by increasing fluid flow and pulled down by gravity as fluid flow decreases. No external power is required, though Swagelok does offer some electronic options.

Once you have flowmeters in place, it's a good idea to follow up with a calibration program, checking every so often that you are still getting accurate readings. Other than that, very little maintenance is required.

How do I determine thread pitch/size?

Like you, we can't tell thread size and thread pitch on a component just by looking at it. But we can provide calipers, combs, and guides that help with identifying threads.

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.

You can find more tips in our article Calipers, Combs, And Guides Help Make Sense of Threads.

What is a field station module?

Swagelok's Field Station Module is a pre-engineered, fully built subsystem that moves samples to the analyzer faster. When this pre-engineered subassembly is placed directly off the supply tap, it lowers the pressure of a gas as soon as possible.

In addition to giving you a fast response time, the field station module reduces condensation in the sample. Higher pressure will squeeze out any water in a gas, causing condensation issues. With a lower pressure, you don't get that change in phase. Lower pressure also provides a safer environment for your personnel.

More information is available in our article Swagelok’s Field Station Modules Are Compact and Ready to Go. Please use a green button on this page to get in touch if you'd like a demo or details.

What are some common sampling system mistakes?

Here are five common mistakes and the problems they can cause. Do any of these sound familiar?

  1. Your gas sampling system has too much volume upstream of the first regulator.
  2. Your liquid sampling pressure is too low.
  3. You’re sampling from a stagnant line.
  4. Your vaporizer is too hot.
  5. Your sample flow is too slow. 

Each of these issues is explained in our article Watch for These Sampling System Mistakes That Can Hurt Your Operations.
