TRIO STEEL – HIC TESTED/SOUR SERVICE STEEL SUPPLIER

HIC (Hydrogen Induced Cracking) occurs when carbon steel is exposed to hydrogen sulphide (H2S) and is the direct result of electrochemical corrosion reactions between the sour service or wet H2S environment. Particularly common to the Oil and Gas Industry where the use of steel pressure vessels is widespread, the risk of this should be considered when hydrogen sulphide partial pressure becomes greater than 3.5mbar. Carbon steel pressure vessels should not be affected by HIC damage where H2S levels are lower than this figure in a normal service life cycle. HIC is prevalent in wet H2S environments, which is often known as sour service and such cracking over a prolonged period of time without inspection, will reach a critical point and the steel component i.e. pressure vessel, could easily fail. Simply put, hydrogen induced cracking damage increases as the level of hydrogen sulphide increases.

 

To ensure that the steel used by various EPC Contractors & oil and gas industry it is essential to supply carbon steel pipes & fittings which meet the sour service environment requirement and are tested to assess their ability to exposure of hydrogen sulphide.

    Hello! I know this is somewhat off topic but I was wondering which blog platform are you using for this site? I’m getting fed up of WordPress because I’ve had problems with hackers and I’m looking at alternatives for another platform. I would be fantastic if you could point me in the direction of a good platform.

    I’m really loving the theme/design of your site. Do you ever run into any web browser compatibility issues? A few of my blog visitors have complained about my site not operating correctly in Explorer but looks great in Safari. Do you have any tips to help fix this problem?
