1.Low alloy pipe stock, low content of P,S
2.Grain size>level 7, equality and thinness
3.Apply SL premium threading connection

According to statistics, there are 1/3 oil and gas wells containing H₂S gas all over the world. In china, there are several oil fields (such as Xinjiang, Sichuan) containing H₂S gas. H₂S gas can cause Stress Corrosion Cracking of casing and tubing, which can result in huge loss. We developed SENWELL 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.
