Product Description

The composite steel pipe end rounding machine is a specialized equipment for the bimetallic composite pipe production line. Its main purpose is to cold expand and shape the composite steel pipe end produced by it after welding, so that the diameter size and roundness of the pipe end within the specified length meet the standard requirements. The working principle of the pipe end rounding machine is to cover the qualified composite pipe that has been stacked and welded on the mold of the expanding head, and expand outward in the radial direction through the mold. The composite pipe expands simultaneously under the action of the mold, causing flow deformation of the pipe and uneven distribution of various internal stresses in the material; By strictly controlling the radial displacement of the mold, the flow deformation of the pipe can be controlled, thereby ensuring that the diameter accuracy and roundness of the pipe end within the specified length meet the relevant standard requirements.
