UOE Pipe Process
UOE steel pipe in the welded pipe market is known for its stable quality and high reliability. It is the world's best quality large straight seam welded pipe, and has become the leading product of long-distance pipeline construction.The ultimate goal of the quality control of UOE welded pipe forming is to make the ovality and peach convex degree of the welded pipe formed by the sheet material through multiple steps meet the precision requirements.UOE process covers the plate edge bending, U forming, 0 forming and expanding process, which is a multi-process integrated forming process.The influence of various technological parameters is complicated, which is directly related to the forming quality of welded pipe.Therefore, it is important to control the UOE forming process so that the deformation of the sheet metal in each stage can be coordinated to improve the quality of the final product.
Pre-bending, commonly known as C forming, is the first UOE forming process.The purpose of prebending is to bend part of the edge of the steel plate along the longitudinal direction, so that the bending radius on both sides of the steel plate is equal to or close to the radius of the steel pipe, so as to ensure the geometric shape and dimensional accuracy of the weld area of the final product.If you do not bend, when forming on a 0 forming press, the edge of the steel plate will still appear flat section, even though the reduction processing is carried out at 1% compression rate along the circumference of the tube billet.This forming defect is difficult to eliminate even in the process of expanding.
