TESTING OF STEELS FOR WET H2S SERVICES
The evaluation of Steels for Wet H2S Service is one of the specialized services which Corrmet offers in addition to many other special materials engineering and metallurgical capabilities and expertise on the broad technical areas related to materials, testing and corrosion engineering.
Hydrogen Induced Cracking (HIC) testing for oil and gas service is defined by NACE standard TM0284. The TM0284 Standard consists of exposing unstressed coupons to a NACE solution TM0177 saturated with H2S at ambient temperature and pressure. After a specified time the coupons are removed and evaluated.
Laboratory Testing of Metals for Resistance to Sulfide Stress Cracking (SSC) in H2S Environments, NACE TM0177:
Method A (NACE Standard Tensile Test)
Method B (NACE Standard Bent Beam Test)
Method C (NACE Standard C-Ring Test)
ASTM G-39 (Bent-Beam Stress-Corrosion Test)
Double Beam for SOHIC Test ( DBC specimens)
Corrmet Engineering Services, Inc. has been selected by the oil and gas industry to perform a series of full scale tests for evaluation of HIC resistance of plate steels for pressure vessels, pipeline steels and steel components such as forged and nozzles.
