Bared Black Painting PLS 2 12M SSAW Steel Pipe

API 5L Psl1 Psl2 Gr. B 3PE 3PP 24Inch Welded Spiral SSAW Steel Pipe

　　SSAW steel pipe for its manufacturing processes mature and lower cost, which is mainly for fluid pipeline.

　　Commonly used continuous molding manufacturing SSAW steel pipe using submerged arc welding method. Molding method within the deck and outside hold two kinds. As these two molding methods are generally insufficient amount of molding, after the kind of the control steel, has a great residual stress, reduces the ability of the pressure of the steel pipe.

　　SSAW steel pipe widely used in the field of petrochemical, heat pipe network and urban water supply and drainage works, million more commonly used in the oil pipeline and natural gas pipeline in the long-distance transmission. Oil and gas field pipeline network almost all spiral steel pipe, with high security, durability and economic rationality. SSAW steel pipe diameter is generally not limited to the width of the plate, by a variety of different specifications of the plate width coil manufacturing, transportation convenience, with steel pipe used to be much lower than the flat steel price for our actual situation. There is a problem of the SSAW steel pipe after welding steel elastic recovery, equivalent to the pipe pre withstand a circumferential tensile stress, the stress will produce stress corrosion and to reduce the bearing capacity of the steel pipe.
