Steel for large diameter pipes Steel for large diameter pipes Steel for large diameter pipes

Steel plates for large diameter pipes or pipeline steel plates are used to make steel pipe for transporting oil, natural gas and other large mouth with a hot-rolled coil steel by welding or heavy plate. Steel plates for large diameter pipes or pipeline steel plates in addition requires a high compressive strength, but also requires a high temperature toughness and excellent weldability.
The main grade of pipeline steel plate are :
