Biaxial stress corrosion cracking testing fixture

A wide variety of environmentally assisted cracking and stress corrosion cracking tests are performed in a dedicated materials laboratory at Southwest Research Institute (SwRI).

 

Standardized Stress Tests

Standardized tests for oil and gas, chemical, and other applications include:

  • ASTM G38

  • ASTM G39

  • NACE TM0177

  • NACE TM0198

Specialized Stress Corrosion Cracking Testing Capabilities

  • Biaxial stress corrosion cracking frames capable of conducting testing in aggressive environments, such as brines with CO2 and H2S

  • Test frames for applying cyclic loads with the measurement of crack propagation rates
