Multispecimen Test Facility for High Temperature, High Pressure Slow Strain-Rate Testing

Source

This paper describes a slow strain-rate test facility in which 6 tension specimens may be tested simultaneously and load-versus-displacement curves for each specimen may be recorded. The facility is designed to operate at a maximum temperature of 500 K (450 °F) and a maximum pressure of 28 MPa (4 ksi). Constant crosshead displacement rates ranging from 2.5 × 10-6 to 2.5 × 101 cm/s (10-6 to 101 in./s) may be obtained. Studies of hydrogen sulfide (H2S)-induced stress corrosion cracking (SCC) of low alloy steels exposed to simulated sour gas well environments (hydrogen sulfide-carbon dioxide-water (H2S-CO2-H2O)) are described. Use of the technique to determine H2S-induced SCC susceptibility of various steels as a function of temperature is shown.
