Spiral Pipe Equipment for Oil and Gas Pipelines

Product Description

Introduction:
Spiral welded pipe machine, also called SSAW pipe mill, is used for spiral weld tube production, steel tubes of different diameters can be made with the same steel strip, same diameter from the steel strip with different widths. The forming part is the key equipment of the mill, spiral welded tube can be produced by single-side welding, double side welding or high frequency welding.
First use the uncoiler 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 forming principle, at last to weld the spiral welding seam by the submerged arc welder.
Spiral welded pipe mill is HUAYE most competitive, most mature technical characteristics product. Product specifications range from Φ60mm to Φ3000mm, divided into international-type mills, special series mills and so on.
Usage of spiral welded pipes
For liquid delivery: water supply& drainage
For gas delivery: coal gas, steam and LPG
For structural use: piling pipe, structural pipe in the field of bridge, dock, road, and construction, etc.
