(1) raw materials are steel coil, wire and flux. Strict physical and chemical tests should be carried out before the input. (2) the connection of steel head and tail is made of single wire or double wire submerged arc welding. After rolling into steel pipe, automatic submerged arc welding is applied. (3) before forming, strip steel is leveled, trimming and planing, surface cleaning and transportation and bending edge treatment. (4) the electric contact pressure gauge is used to control the pressure of the two sides of the conveyor under the pressure of the cylinder, so as to ensure the smooth conveying of the strip. (5) use external or internal control roll forming. (6) the weld gap control device is adopted to ensure that the weld gap meets the welding requirements, and the pipe diameter, the wrong side quantity and the weld clearance are strictly controlled.
