Large diameter straight seam steel pipe technological process and main equipment(1)

The two plate edges are processed into the desired form at a time. The steel plate edge milling machine: machine the two sides of the plate material for tube making and make the parallelism of the two plate edges within the specified tolerance range, preparing for manufacturing high-precision steel pipes.

Steel plate pre-bending machine: the edge of the steel plate with welded grooves processed by the milling machine is pre-bent. To prevent excessively long straight edges from being formed by the forming machine to ensure the roundness of the steel plate.

Fully automatic steel tube forming machine: complete the bending forming of various metal sheets.

Perform further seaming and pre-welding. Steel pipe pre-welding machine: the qualified open tube blanks formed by the forming machine are prepared for internal and external welding.

Welding trolley transports the workpiece to travel along the track, double-wire internal welding machine: used for automatic submerged arc welding of large-diameter straight seam steel pipe, and cooperate with the host to realize welding of the workpiece.

Welding trolley transports workpieces along the track, double-wire external welding machine: used for automatic submerged arc welding of straight seam steel pipes, and cooperates with the host to realize welding of workpieces.
