Sprial welded pipe roll forming machine within diameter range from 630-3650mm

           Diameter ofφ630~φ3520 Spiral Welded Tube Machine quotation

Brief introduction:

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:

Decoilingà remove the unneat and unstraight part at the beginningà feed coil to machineà Vertical roller to fix the coil and weld two coils together.--> forming stationà inner and outside welder systemà flying and tracking cutting saw systemà runout table

Main part function:
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.
