What is Sour Service Corrosion

Cracking involving corrosion and tensile stress in the presence of water and H2S is a major problem for oilfield structures that contain H2S and can cause cracking of materials by the mechanisms known as Sour Service Corrosion (SSC).

Testing in Hydrogen Sulphide containing environments is undertaken in a number of the Exova's laboratories. The most extensive facility is situated at the Exova Corrosion Centre. Singapore Test facilities established based on the decade old proven technology by qualified internationally recognised experienced team.

Hydrogen-Induced Cracking (HIC) Tests

Evaluating the resistance of pipeline and pressure vessel plate steel to Hydrogen Induced Cracking caused by hydrogen absorption from aqueous sulfide corrosion.

Sulfide Stress Corrosion (SSC) Tests

A polythionic acid (sulfurous acid and hydrogen sulfide) environment provides a way of evaluating the resistance of steels and related alloys to sulfide stress corrosion cracking. This practice can be applied to wrought products, castings, weld metal and other materials to be used in environments containing sulfur or sulfides.
