Strip Coil Processing and Manufacturing Equipment China Factory Longitudinal Welded Pipe Unit with The Rapid Development

Product Details

Spiral welded pipe production line with most competitive and mature unit

Introduction to spiral welded pipe unit:

spiral welded pipe unit is a steel pipe formed by rolling low-carbon structural steel or low-alloy structural steel strip into pipe blank through the forming machine according to a certain forming angle, and then welding the spiral pipe seam with submerged arc welding machine. The utility model has the advantage that the steel pipe with large diameter can be produced with narrow strip steel.

Application of spiral welded pipe unit:

For liquid transportation: water supply and drainage.
For gas transmission: gas, steam and liquefied petroleum gas.
For structure: pile driving pipe, pipe for bridge, wharf, road, building structure, etc.

The product specification of spiral welded pipe unit of our company is
pipe diameter φ 90~ φ 3500mm, wall thickness: 1 ~ 25mm, all models made of Q235 ~ X80

Process flow of spiral welded pipe unit:

Winding up → uncoiling → leveling → shearing and butt welding → disc shear → edge milling → delivery machine → pre bending guide plate → forming → internal welding → external welding → cutting → pulling out → flat head chamfering → hydrostatic test → collection of finished products
