【概要描述】Spiral welded pipe production line is often used to produce spiral welded steel pipe equipment. Spiral welded pipe is made by rolling hot rolled steel strip into a spiral shape and then welding it. The following is the general process flow of spiral welded pipe production line: 1.Strip uncoiling: Unroll the hot rolled steel strip from the reel. 2.Cutting and docking: Cut the developed steel strip to the required length, and butt the multi-section steel strip into a continuous steel strip. 3.Forming: The steel belt is gradually curled into a spiral tube after a number of roller forming devices. 4.Internal welding: The internal welding machine is used to weld the weld inside the spiral tube, usually using submerged arc welding for welding. 5.External welding: After the internal welding is completed, external welding is carried out, also usually using submerged arc welding. 6.Weld inspection: Non-destructive testing of the weld (such as ultrasonic inspection) to check whether there are defects. 7.Sizing and straightening: The spiral welded pipe is shaped and corrected by the sizing and straightening device to ensure its dimensional accuracy and straightness. 8.Cutting: According to the length required by the user, the spiral welded pipe is cut into a fixed length. 9.Quality inspection: Quality inspection of the finished pipe, including size inspection, weld strength test, surface defect inspection, etc. 10.Anti-corrosion treatment: According to the need for spiral welded pipe surface anti-corrosion treatment, such as coating, galvanized, etc. 11.Packaging and transportation: The spiral welded pipe that has been treated and tested is packaged and transported to the customer. Spiral welded pipe production line has the advantages of high production efficiency, good quality and low production cost, and is widely used in oil and gas transmission, water supply engineering, sewage treatment and building structure.
