Large-diameter thin-walled welded pipes are important pipes for transportation and structure in industrial production. They are suitable for long-distance pipelines and large steel structure projects in industries such as petroleum, natural gas, and chemicals.

This production line is mainly customized according to customer needs. The welded pipes produced have large diameters, thin walls, and good appearance. They can withstand high pressure and reduce weight and installation costs

Production process:

Process: loading → unwinding → straightening → clamping and leveling → shearing and welding →Accumulator→ forming, high-frequency extrusion welding, removing external (internal) burrs, weld polishing, weld flaw detection, water cooling, sizing, rough straightening → Saw cutting → conveyor rollers → automatic packaging → marking → inspection and collection → storage
