Liquid and gas permeation testing is often performed on polymers, seals and other susceptible materials used in the oil and gas sector. Element’s services are designed to ensure the safety and longevity of these materials by measuring permeation coefficient (permeability), diffusion coefficient (diffusivity) and solubility coefficient. 

During liquid or gas permeation testing, polymers can be tested at pressures up to 10,000 psi (690 bar) and temperatures from 20 to +250 ° C, measuring permeability characteristics of deep well components (seals, pressure barriers, liners, etc.), fuel system components, hydrogen storage tanks and chemical processing infrastructure. 

Additional Liquid and Gas Permeation Services

Our test capabilities include sweet and sour gas permeation testing, as well as liquid permeation testing and analysis of permeated gases and mixtures. For projects with more challenging requirements, our labs can use finite elemental analysis (FEA) to model fluid passage through more complex shapes and components. 

In addition to well-established industry standards, we can work with you to design and implement custom test plans, often integrating several polymer testing methods into a single test program.  For more information about our service, or to request a quote, contact us today.

Gas Permeation

Gas permeation testing uses sweet and sour gases to evaluate coupon samples, hoses, tubes, pipes, o-rings and sealing elements.

We provide testing at temperatures from -20 to 250 °C and at pressures up to 690 bar. We commonly test a variety of industry-recognized standards, including API 17 J, ASTM D1434, ISO 2556 and ISO 4080. Additionally, our experts can create customized permeation tests for O-rings and sealing elements.

Some of the gases we can test include: 

  • Carbon dioxide (CO2)
  • Methane (CH4)
  • Ethane (C2H6)
  • Nitrogen (N2)
  • Hydrogen (H2)
  • Hydrogen Sulphide (H2S)

Liquid Permeation

Element conducts liquid permeation testing with a range of fluids, including water, oil, solvent, brines, and alcohol mixtures.

Liquid permeation testing for hoses, tubes and pipes can be performed up to 130 °C, and at vapor pressures described in ISO 8308. Custom permeation testing is also available for hoses under pressure up to 300 bar

.For rubber sheets and flat components, we can reach temperatures of 200 °C using the cup weight loss method according to SAE J2665, ASTM E96, ASTM D814, ISO 6179 (BS 903-A46), and ISO 2528.

If you have a unique need, our experts can assist in creating a custom test procedure.
