Performance Testing

We are ISO 23936-2, NACE TM0192 & API 6A Accredited

                                                                 
      >We Perform the Following Services

Rapid Gas Decompression (RGD)

Elastomer seals can be damaged during the rapid release of pressurized gas. The damage only occurs during and after high pressure is released, and is worsened by high temperatures. RGD damage including surface blisters, splits, and internal damage are shown below.  We are NORSOK M710 qualified to assess your material using a comprehensive damage rating system, and well-defined acceptance criterion, and and have the knowledge and experience to test your material using parameters that will best mimic field conditions.

hp htHigh Pressure/High & Low Temperature

We offer a wide range of testing for polymers exposed to harsh environments at critically high and low temperatures.
We provide pressure testing up to 40,000 psi at temperatures from Cryogenic to 600°F to ensure your material operates successfully in the field.

 

 

 PR2 

We offer API 6A Appendix F PR2 qualification for components which will be commissioned in remote and hostile environments to give our customers absolute confidence that their components can withstand the most demanding environments throughout their working life.

The PR2 test elevates the component to extreme high and low temperatures while dynamically cycling it under various pressure conditions to ensure the integrity of the seals and mechanics of the component.

PR2 Testing Capabilities:

  • Numerous environmental chambers for testing a wide variety of components
  • Largest environmental chamber measures 2m x 2m x 2.4m
  • Temperature range -80oC to 204oC (-112oF to 399oF)
  • Gas test pressures to 22,500 psi

 CSR

Compressive Stress Relaxation measures the extent & rate of decay of the force that the elastomer is exerting against two mating plates after being exposed to aging conditions (air or fluid) over a specific period of time & temperature. We test by measuring the sealing force exerted by the sample under compression to determine the predictive service life of the material by measuring the sealing force decay as a function of time, temperature and environment. 


Extrusion Resistance

extrusion resistance

Extrusion occurs when system pressure forces the seal from its groove and into the clearance gap with-in the seal housing. Proper groove dimensions and seal selection combined with elastomers designed to resist extrusion can prevent this type of failure. The potential for extrusion to occur is greater with a larger gap.  O-rings are tested under differential pressure at temperatures up to 300°C to quantify extrusion resistance. Short-term (30 minute), long-term (days), and cyclic-pressure extrusion tests can be run.

Extrusion pressure is dependent upon many factors but a constant set of gland dimensions are established to compare extrusion properties of materials. Both rubber O-rings and plastic V-rings can be tested are shown below as an example. 

 


  Bonding Tests

Single lap shear bonding specimens are used to determine the bonding performance of the elastomer to steel used in the tool.

Instron

stretch plasticLoad measurement accuracy to +/-0.5% of reading down to 1/1000 of load cell capacity and fast, synchronized data acquisition rates up to 2,500 points per second. The most common uses of these mechanical testing systems are for tensile, compression, bend, peel, shear, tear and cyclic tests. Using long travel, clip on and video extensometers to measure specimen strain.

Capable of meeting test requirements per ASTM, ISO, DIN, TAPPI, GB, JIS, ANSI, NAS, etc…
