Our ACA company manufactures large-diameter straight seam steel pipe production line, which is running continuously in our users' factories in China. Our JOCE welded pipe line achieves automated production, greatly facilitating users' visualized quality monitoring and management of the production process.
The JCOE pipe production line processes the following steel pipes:
1. Pipe diameter: 406mm-1420mm, wall thickness: 6mm-50mm, pipe length: 6m-12m.
2. Can process steel pipes of materials: Q235A, Q345, X42, X46, X56, X60, X65, and X70.
3. Production capacity: 100,000 tons/year
4. Welding technology: Gas shielded welding is used for pre-welding, and submerged arc welding is used for final welding to ensure the quality of the weld seam.


5. Equipped with a large JCO forming machine: 12,000 tons





6. Steel pipe precision: Ovality ≤1%, Straightness deviation ≤0.2%
7. Equipped with complete JCOE pipe making machinery that meets standards such as APL: such as pipe X-ray inspection equipment, ultrasonic detectors, pipe sizing machines, and pipe hydrostatic testing machines. Customers can produce oil and gas pipelines that meet high-standard quality requirements such as ASTM 53, API Spec 5L, ASTM A252-89, and EN10217, based on market demand.
The JOCE pipemill production line is a specialized piece of equipment for manufacturing large-diameter straight seam submerged arc welded (LSAW) pipes, The LSAW Welded Pipe Production Lines employs the JCOE (JCO forming + pre-welding + internal welding + external welding) process. It features high precision and efficiency, but also complex equipment components, requiring corresponding production and supply capabilities.
ACA group, as one of the few enterprises capable of producing and supplying complete JCOE welded pipe production lines, supplies domestic and international users with JCOE welded pipe production lines capable of producing straight seam steel pipes with a maximum diameter of 1626mm, with a capacity of up to 150,000 tons per year. The main equipment performance has reached international advanced levels, and our JCO - LSAW Welded Pipe Production Lines, JCOE pipeline forming machine, have been successfully exported to Saudi Arabia, Mexico, Brazil, Uzbekistan, Kazakhstan, Russia, and other countries. The welded Pipelines produced by our equipment have also been designated for use in major national oil and gas pipeline projects.
