Main equipment of producing lsaw pipe

Main equipment of producing lsaw pipe are as follows:

Steel milling machine: The two sides of the sheet metal for machining are machined, and the two sheets are processed into the desired form at one time. And the parallelism of the two plates to achieve the specified tolerance within the scope for the manufacture of high precision steel pipe to prepare.

Plate pre-bending machine: Milling machine will be processed on both sides of the welded steel plate edge pre-bending. To prevent the molding machine forming steel tube in the long straight edge, the edge of the steel plate will have the same radius of curvature of the steel pipe will be shaped. To ensure the roundness of steel.

Automatic steel tube forming machine: To complete the bending of various sheet metal forming.

Pipe pre-welding machine: Molding machine forming qualified open pipe blank, for further joint and pre-welding. Prepared for internal and external welding.

Double wire welding machine: Used for automatic submerged arc welding of large diameter straight seam steel pipe, welding trolley to transport the workpiece to walk along the track. With the host to achieve the workpiece welding.

Double wire welding machine: For automatic submerged arc welding of straight seam steel pipe, welding car to transport the workpiece along the track. With the host to achieve the workpiece welding.

Pipe finishing machine: Long round tube with poor roundness exerts strong pressure from outside to change roundness of pipe. To achieve the relevant norms and requirements.

Gantry mobile sensory straightening machine: For the steel cylindrical tube straightening.

Straight-seam flat-head chamfering machine: The straight seam steel pipe ends according to the provisions of the blunt and chamfer angle.

Steel pipe expanding machine: To eliminate stress.

3000T hydraulic pressure testing machine: pressure test of welded pipe. Eliminate welding stress and forming stress, check whether the pipe under the specified pressure infiltration defects. Thus ensuring the use of steel performance.
