Gas distribution systems
Grab Distribution Systems
Gas distribution systems must effectively deliver gases from a high-pressure source to the facility at the pressure and flow rate required by each application. Systems are built around one or a series of pressure regulation steps and may include four typical subsystems:
- Swagelok source inlet
- Swagelok gas panel
- Swagelok point of use
- Swagelok changeover

Best Practices for Successful Sampling
While individual considerations may be required based on the uniqueness of your process and operations, representative sampling typically adheres to a few primary best practices.
What is Grab Sampling?
Grab sampling, also known as lab sampling or spot sampling, is the collecting of a sample of liquid or gas in a pipeline, tank, or system with the intent of transporting the sample to a laboratory for analysis.
Sampling Basics
Depending on the process phase, temperature, consistency, chemical makeup and other factors, there are a variety of approaches that can be used to extract a sample.
Specifying a Grab Sampling System
Given the wide variety of configurations available, there will be several criteria to consider in order to properly specify a grab sampling system.
