API tubing and casing of various steel grade have been adopted in the oil and gas well world wide, but along with the exploration condition getting critical and depth getting deeper, API standard tubing and casing are not suitable with the oil well medium of H2S, Hydrogen sulfide often casuses sulfide stess crack on tubing and casing, which leads to hydrogen brittleness on tubing and casing as well as great losses. Our products of H2S corrosion resistance tubing and casing is R&D through long term study to oil well sites, such as 80S, 90S, 95S, 100S, 110S and 80SS, 90SS, 95SS, 100SS, 110SS, these tubing and casing have very good anti sulfide crack performance.
a. Sour service purposes
80S, 90S, 95S, 100S, 110S, suitable for normal corrosion condition.
b. Special sour service purposes
80SS, 90SS, 95SS, 100SS, 110SS, suitable for more severe corrosion condition.
