In recent years,there has been development of several significant pipeline projects for the transmission of oil and gas from deep water environments.The production of gas transmission pipelines for application demands heavy wall,high strength,good lower temperature toughness and good weldability.To overcome the difficulty of producing consistent mechanical property in heavy wall pipe Shougang Steel Research in cooperation with the Shougang Steel Qinhuangdao China(Shouqin)4.3m heavy wide plate mill research was conducted.
