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 :
