At present, there are 1/3 oil and gas wells containing H2S gas all over the world. In china, there are several oil fields (such as Sinkiang, Szechwan) containing H2S gas. H2S gas can cause Stress Corrosion Cracking of casings and tubings, which can result in huge loss. We developed SL H2S Corrosion Resistance Petroleum Pipes associating with foreign companies in order to solve the hereinbefore problem. The test showed this casing type can be used in wells with content of 8% H2S gas and could well-solve corrosion cracking.

Product Features:

1.Low alloy pipe stock, low content of P, S;
2.Grain Size > level 7, equality and thinness;
3.Apply SL premium threading connection, good strength and reliable sealing;
4.Excellent H2S corrosion resistance, applied by middle/deep wells containing H2S gas.
