Design of Curvature Radius of Finishing Roll for Crimp JCO

2. Introduction to Finishing Process of Crimp JCOE Steel Pipe. For the crimp JCOE process, there is no pre-bending process in the whole process, and there is a flat area along the longitudinal edge of pipe opening after forming. The length of the flat area along pipe seam varies with the diameter of the pipe. Difference between uoe and jcoe pipeThe view from the two production processes, both in the process of forming the front and rear is basically the same, the biggest difference is that the molding way. The UOE forming mainly consists of two steps:the U forming and O molding. And JCOE forming part of the program is divided into six parts, production efficiency is greatly reduced.

Differences between JCO and UOE Line Pipe - Pipelines

Feb 10, 2005 · JCO - plates pressed in J form first, then in C form and then in O form before before longitudinal welding. Welding is followed by cold expansion. Apparently the newer of the two processes. UOE - plates pressed in U form, then in O form before longitudinal welding. HIGH WALL THICKNESS DLSAW PIPES FOR SOUR The pipe manufacturing process must be controlled by selecting the proper radii of crimping tools, edge mill bevel angle and the radius of the JCO forming tool and the number of strokes. The pipe opening gap after complete forming is minimized before entering the continuous tack welding station. The manufacturing process of

JCOE (J-ing, C-ing and O-ing) Pipes
