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. We at Trio Steel are a pioneer in supply of various HIC Tested Products as below:
API 5L GR B PSL2 HIC TESTED PIPES
API 5L X42 PSL2 HIC TESTED PIPES
API 5L X46 PSL2 HIC TESTED PIPES
API 5L X52 PSL2 HIC TESTED PIPES
API 5L X56 PSL2 HIC TESTED PIPES
API 5L X60 PSL2 HIC TESTED PIPES
API 5L X65 PSL2 HIC TESTED PIPES
API 5L X70 PSL2 HIC TESTED PIPES
API 5L X80 PSL2 HIC TESTED PIPES
These pipes are available in both seamless and welded category depending on the sizes required. Apart from this we can also supply HIC Resistant Plates like ASTM/ASME A/SA 516 60/65/70 & subsequently the A671/A672 GR CC 60/65/70EFW PIPES
