Product Description

Introduction:
Spiral welded pipe production machine is used to manufacture spiral seam welded pipe. It can produce steel pipes of different diameters with strips of the same width, and produce steel pipes of the same diameter with strips of different widths. Spiral pipe welding machine (spiral steel pipe machine) is mainly for front swing type and rear swing type.

The pipe machine is used to process strip coils through uncoiling, leveling, shearing, forming, welding and other processes to produce spiral welded pipes that comply with relevant national standards. It is suitable for water, sewage, air, heating steam and flammable fluids Steel pipes for fluid transportation pipes are also applicable to other steel pipes for fluid transportation pipes with similar requirements.
Our pipe machine is featured with intense competition of strength and technique.

Reference Project
This pipe machine is to uncoil the steel coil into steel strip which is formed by forming machine to make spiral welded pipe. Φ406-Φ2200 spiral welded pipe mill apply front swing type mill. The spiral welded pipes are mainly used as delivery pipeline for petroleum,   natural gas, water, coal gas, as well as structural pipe and piling pipe.
Right hand spiral forming, center positioning, front swing, discontinuous production.
The inner and outer spiral welding line employs DC-AC double wire submerged-arc automatic welding, strip steel end welding employs DC single wire submerged-arc automatic welding (the welding power supply is used with outer welding together)
