The spiral is also known as the spiral steel pipe and spiral welded pipe, low carbon structural steel or low alloy steel strip according to the angle of the spiral line (called the forming angle) rolled into a tube, and then the tube welded together made , it can be a narrow strip production of large diameter steel pipe. The coil is mainly used for oil and gas pipelines, its specifications OD * wall thickness. Side welding and double-sided welding spiral welded pipe should ensure that the hydrostatic test, the tensile strength of the weld and cold bending performance required. Edit this paragraph, the production process (1) raw material strip volume, wire, flux. The input to go through rigorous physical and chemical testing. (2) strip head and tail docking, using a single wire or twin-wire submerged arc welding and automatic submerged arc welding rolled into the steel pipe. (3) before forming the strip after flattening, cutting, trimming, edge planing, transportation and to the curved side surface cleaning. (4) electric contact pressure gauge to control the conveyor both sides of the pressure cylinder pressure to ensure the smooth delivery of the strip. |
