Overview
Build to withstand — certify for safety in sour environments
Manufacturing industries in oil & gas production must qualify materials against sour-service tests to ensure reliability in H₂S environments. Passing SSC evaluations helps prevent catastrophic failures and enhances component lifespan under sour conditions.
ISO/IEC 17025:2017 accredited practices and reporting.
Gas options
Single gas or mixed-gas exposure
Oil & gas infrastructure
Tests target pipelines, pressure vessels, and other critical components used in sour environments.
Envelope
Test conditions
Atmospheric pressure
Testing at ambient temperature and atmospheric pressure.
Up to 250 °C & 50 bar
Up to five-gas mixtures supported at elevated temperature and pressure.
Methods
SSC test methods (A–D)
Tensile test
Constant tensile load applied in H₂S to assess stress-corrosion cracking thresholds under high tensile stress.
Bent-beam test
Two-point or four-point stressing with exposure to H₂S to generate variable stressing scenarios.
C-ring test
Ring specimens experience tensile and compressive stresses, simulating multi-directional service conditions.
Double-cantilever beam (DCB)
Fracture-mechanics approach measuring crack-growth rates in pre-cracked specimens under sour conditions.
