Introduction


1.Spiral welded pipe mill is used to roll the low carbon steel/ low alloy steel strip into tube by a certain forming angle, further weld it into steel pipe by sub-merged arc welder.


Large diameter pipes can be produced with narrow steel strip.



2. Function


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.



3.Process flow
Feeding→uncoiling→leveling→shearing& butt welding→rotary shear→edge milling→main drive→pre-bend& guide board→forming→inside welding→outside welding→cutting off→pull out→end-facing& beveling→hydrotesting→collection
