2. Use double-wire or single-wire submerged arc welding, the head and tail of the strip are butted, and the automatic submerged arc welding is used for repair welding after rolling into a steel pipe.
3 Before the spiral steel pipe is formed, the strip steel is subjected to edge trimming, leveling, edge planing, pre-bending treatment and surface cleaning and transportation.
4 In order to ensure the smooth conveying of the strip, an electric contact pressure gauge is used to control the pressure of the cylinders on both sides of the conveyor.
