Both JCOE process and RBE process are steel pipe production processes used to make long welded pipes.
1、The JCOE process (also known as the J-C-O-E process) is a hot-rolled coiled straight seam welded pipe production process. Its full name is "J-shaped bending, C-shaped forming, O-shaped retraction, and E-shaped expansion". The steel plate is formed into several processes such as bending, forming, retraction and expansion. This process is generally suitable for the production of steel pipes with large diameter, high pressure and large wall thickness. The JCOE process can produce steel pipes with diameters ranging from 406mm to 1422mm and wall thicknesses ranging from 6mm to 80mm.
2、The RBE process is a production process of longitudinally welded pipes, and its full name is "Reverse Bending and Expanding Process". The process is mainly completed by first bending the hot-rolled steel plate into a U shape, then reversely bending it into a straight seam welded pipe, and performing subsequent processes such as welding, annealing, straightening, and flaw detection. The process is suitable for the production of steel pipes with a diameter of 406mm to 1626mm and a wall thickness of 6mm to 65mm.
Therefore, the difference between the JCOE process and the RBE process lies in their different pipe-making processes, and the diameter and wall thickness range of the produced steel pipes are also slightly different.
