Steel Plate For Linepipe - Koryo Steel

More than two million tons of sour-gas-resistant linepipe plates and high-toughness linepipe plates for thick-walled deep-sea lines testify to the success of our high-quality products.Steel grades.API API 5L-B,X42,X46,X52,X56,X60,X65,X70,X80,X100,X120Recent Progress and Application of Bainite Steels for High For the constant transmission of gas through a pipeline,steel weight decreases linearly with an increase in the strength of the linepipe irrespective of pipe size and internal pressure.Thus,high-strength large-diameter linepipe up to X120 has been developed and is now being applied to reduce pipe costs,transportation costs and construction costs.Property requirements for automotive and linepipe Property requirements for automotive and linepipe applications. And if the gases or the oils also contain sulfur,the pipeline should have good resistance to sulfide stress corrosion cracking.If you look at this figure,there are various type of steels being used for low temperature application such as the API,American Petroleum Institute
