Swagelok Sample Cylinders

Sample Cylinders

Our sample cylinders have seamless construction for uniform thickness and volume, with a smooth neck for easy cleaning and no fluid retention. Cold-formed NPT threads and heavy-wall ends enhance strength and flare resistance.

TPED Compliant Products

Swagelok's cylinders for chemical transport meet DOT/TPED standards, offer uniform thickness, easy-to-clean transitions, and strong connections, available in stainless steel with valves and various accessories.

Sample Cylinder Assemblies (GSC)

Swagelok's Grab Sample Cylinders are available in five standard sizes and offer a range of materials, with options for purge bypass tubes, quick connects, protective features, and specialized interior coatings for advanced applications.

GSM - Gas (Standard Gas Sampler Without Purge GSM-G-1(-N)

Grab Sample Module - Gas

An example Standard Gas Sampler Without Purge is shown here. Part of the value of a Swagelok grab sample solution is that a standard design can be easily customized to your specific process requirements. And we offer quick local support for future.

GSM - Liquid

Swagelok's Standard Liquid Sampler configuration (shown here without purge) is for general use for liquid sampling. It is recommended for fluids that are non-toxic and are not susceptible to settling in the sampler, and for when the return is sent to flare.

Liquid Only Sampling Systems

Swagelok's Liquid Sampler with Fixed Volume and Continuous Flow prevents overfilling of the sampler in systems where continuous flow is required from inlet to outlet. A sample is drawn into a fixed volume reservoir, held, and then dispensed into a sampler.

Miniature Sample Cylinders

Our miniature sample cylinders feature 3/8 in. tube adapters for low-volume fluid transport. Choose from single/double-ended, corrosion-resistant stainless steel designs with capacities of 10, 25, and 50 cm3, and 1000 psig rating.

Outage Tubes

Swagelok's outage tubes, crafted from 316 stainless steel or alloy 400, come in 1/4 or 1/2 in. NPT sizes, and are welded to adapters or tees for secure integration into sample cylinders.

Quick Connects

Swagelok's quick connect fittings allow for easy, tool-free operation and are designed to reduce spillage and air inclusion. They are available in various configurations with single or double-end shutoff options.

Instrumentation Options & More

Additional instrumentation options include gauges, flowmeters, and transducers; sample coolers; threaded and flanged connections. We also offer enclosures and stands (see photo); automation; and exotic alloys.

Swagelok Edmonton Field Advisor Tom Webster has completed a year-long training and testing regime under experts like Tony Waters—arguably the leading authority on industrial sampling systems—and expanded our capacity for conducting Sampling System Evaluation and Advisory Services (SSEAS). During a Sample System Audit, Tom (and, if needed, a team of peers) examines your systems and identifies steps to boost consistency, reliability, and efficiency.

"SSEAS is a full system evaluation," Tom says. We take a holistic look at the facility and report with recommendations and suggestions on how to improve plant efficiency and safety. We can do wake frequency calculations and time delay calculations, advise on line sizing, and help with sample system design."

Switching Valves

Our Grab Sample Modules use a 40G series ball valve as a switching valve, available in 2 or 3 valve configurations, enabling fluid routing control, simplifying sampling sequences, and reducing errors with clear operator indications. It is standard on GSM and fixed volume GSL panels.

Grab Sample Valves

The Swagelok Grab Sampling Valve (GSV) is designed to minimize leaks, safeguard operators and the environment, and improve sample quality, while saving time and costs. Its replaceable needle assembly and seal-free design ensure easy maintenance and robust performance.

Material Matters

In stainless steels, chromium and nickel are critical for corrosion resistance and ductility. Not all bar stock is the same. Swagelok 316/316L stainless steel tube fittings and instrumentation valves contain more nickel and chromium than minimally required by ASTM standards for bars and forgings.
