 Spiral, also known as spiral or spiral steel pipe, structural steel is low carbon or low alloy structural steel strip at a certain point of the spiral line (called the forming angle) rolled into a tube, and then seam welded pipe made of It can be produced with a narrow strip large diameter steel pipe. Coil is mainly used for oil and gas pipelines, its specifications with diameter * thickness, said. There are single-sided welding of spiral and double-sided welding, the pipe should ensure that the pressure test, the tensile strength and cold weld performance to meet the requirements.
