Product Description

The working principle of the steel pipe end expanding machine is to cover the formed and internally and externally welded qualified steel pipes on the expanding head mold, and expand them outward in the radial direction through the mold. Under the action of the mold, the steel pipe expands simultaneously, causing flow deformation of the pipe and the redistribution 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, so that the diameter accuracy and roundness of the pipe end within the specified length can meet the requirements of API5L standards.
