Welded Pipes

Welded steel pipe (steel pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding. Steel Pipe can be divided into Cold Drawn Smls Steel Pipe Hot Rolled Smls Steel Pipe Galvanized Steel Pipe. Features of ERW pipe Low cost: the low raw material cost and manufacturing cost make it prices more competitive than longitudinal seam submerged-arc welded pipes and seamless pipes. High Weld Seam Security: As a result of...

Steel Pipe can be divided into Cold Drawn Smls Steel Pipe Hot Rolled Smls Steel Pipe Galvanized Steel Pipe. Range of LSAW pipes for oil and gas pipeline LSAW pipes are mainly used as long distance transportation pipeline for oil, gas, liquid coal etc. on land and offshore. And also can be applied as construction pipes on offshore...

Cabon steel grade SAE 1020 is a low hardness and low tensile strength alloy. The Brinell hardness of the SAE 1020 Steel Tube ranges between 119 – 235, whereas its tensile strength is between 410 MPa to 790 MPa. Though it lacks some of the characteristics of a conventional carbon steel grade, the SAE 1020 Steel Tube exhibits other important characteristics such as high strength, high machinability, high ductility as well as good weldability. A low carbon content in its chemistry makes the pipe...

UOE is a method used for production of longitudinally welded large diameter pipes. Longitudinal edges of steel plates are first beveled using carbide milling equipment. Beveled plates are then formed into a U shape using a U-press and subsequently into an O shape using an O-press. In accordance with different requirements of the customers, the welded pipe can be expanded either by mechanical or hydrostatic expander to improve dimensional accuracy, and eliminate residual stress. Steel Pipe can...

Product Introduction Welded pipe is an electric welded round pipe that is an alternative to steel pipes.It is a structural grade tube that is suitable for a wide variety of applications where dimensional accuracy and precision tolerances is not a primary concern.A raised weld seam is present inside the pipe. Spiral welded steel pipe is a kind of practical steel pipe, now it has been widely used in small and medium-sized construction site construction facilities, not only that, spiral steel pipe...
