Straight seam steel pipes can be categorized into high-frequency straight seam resistance welded pipes (ERW pipes) and submerged arc welded straight seam steel pipes (LSAW steel pipes) based on the production process. Submerged arc welded straight seam steel pipes are further classified into UOE, RBE, JCOE, etc., according to their forming methods.

 

Among these, JCOE steel pipe production is known for its simplicity, high production efficiency, low cost, and rapid development. These characteristics make JCOE steel pipes crucial in large-scale pipeline projects, water and gas transmission projects, urban pipeline network construction, steel structure buildings, bridge piling, municipal construction, and urban development.

 

The JCOE process involves several stages, including bending, jointing, internal welding, external welding, straightening, and flattening, ensuring the final product meets relevant standards. The inner and outer surfaces of the steel pipe must be smooth, free from folding, cracks, delamination, lap welding, arc breakage, burn-through, and other local defects exceeding the lower wall thickness deviation. Minor local defects within the lower wall thickness deviation are permissible.

 

Advantages of JCOE forming in straight seam double-sided submerged arc welded pipes include:

1. Fully automated process;

2. Submerged arc welding provides strong heat exchange and protection, resulting in high-quality welded products;

3. The arc is submerged under the welding flux in automatic welding, allowing for the use of large currents and achieving high welding efficiency.
