Brief Introduction of sprial welded tube machine

Spiral welded pipe machine is used to big diameter pipes by spiral welding method. By decoiler to uncoil and level the steel coil, and send the strip to forming machine by certain angle, then bend the pipe by certain angle based on three-roller forming principle, at last weld the spiral welding seam by the submerged arc welder. It is also called SSAW pipe mill.

Working process of Spiral Welded Tube Machine:
Decoiling--> remove the unneat and unstraight part at the beginning--> feed coil to machine--> Vertical roller to fix the coil and weld two coils together--> forming station-->inner and outside welder system-->flying and tracking cutting saw system-->runout table

Supported material:

Galvanized Sheet, carbon steel coil and others.

Diameter range:160mm-3250mm

Thickness range:2-10mm

Where the sprial welded pipe machine used for?
1. Transfer piping for high-intensity petroleum, natural gas with API standard.
2. Transfer piping for low-pressure fluid flow, city gas and drainage pipeline.
3. Pile driving tube for project.
4. Steel tube for industrial structure.
5. Other usages.

Main function of each part of Spiral Welded Tube Machine:

1. Decoiler system firstly is used to open and feed the first edge of coil to the strip edge joining system. Meanwhile this part also bends the trailing edge of the coils.
2. Side guide rollers are designed to feed the coil in the correct position from the decoiler to the forming section. And the pivot line roller and the cross side rollers are positioned by the hydraulic cylinders; the position will not be changed. Its functions are fixing the coil. And there are also some non-pivot rollers which are moveable for eleiminating the minor movements of the stripe.
3. For leveling and make sure the input coil straight, there are some non-driven rollers to level coil stressed by the hydraulic cylinders.
