The first batch of 18.55mm highest grade acid-resistant pipeline steel X65MS developed by Tangshan Iron and Steel Company of HBIS Group has successfully passed the SSC test which is for resisting H2S and other acid gas corrosion. This marks that Tangshan Steel already has production capacity for a full series of acid-resistant pipeline steel BMS-X65MS and achieves a breakthrough in the high-end pipeline steel industry.
The acid-resistant pipeline steel is mainly used for manufacturing oil and gas pipelines that will transport special oil and natural gas with high contents of H2S and CO2 to the Middle East and other regions. The X65MS is the highest grade used in both domestic and overseas markets with higher added value and price.
