Plain carbon steel 51crv4 steel chemical composition stock size
With the development of remote oil and gas fields, polar oil and gas fields, offshore oil and gas fields and acid oil and gas fields, oil and gas pipeline engineering is facing challenges of high-pressure transmission and harsh environment such as low temperature, large displacement, deep sea and acid medium. In order to ensure the enthusiasm and safety of pipeline construction and operation, the basic requirements and development trend of , pipeline steel are high strength, high toughness, large deformation, thick wall, high corrosion and good weldability.
