Industry Stainless Steel Tube Mill Line is designed for manufacturing stainless steel straight welded pipe for construction, transportation, metallurgy , and machinery and vehicle industries. It adopts long steel strip as the material to manufacture steel pipes according to requested size by cold rolled forming and argon arc welding method. To be specific, the stainless steel pipe production line can produce round pipe, square and rectangular tube, as well as section steel through cold rolled forming and TIG welding technology.

Details of several parts wholes line
Uncoiler :
Function: support rolled plate and strip tension for erw pipe mill production line, by the frame, main shaft, increases of drum, brake.
There are 3 types: pneumatic, hydraulic and manual. | |
Cut butt welding 2 Types: Automatic & Manual
Shear the end of each strip coil, then welding them together, so that pipe making welding machine line can be continue production.
| |
Strip Accumulator
Function: storage strip to keep continue production2 Types: Horizontal / Vertical | |
Forming SectionFunction: forming the tube from strip Advantage:A.Advanced forming technicalB.One-stage molding platformC.Reliable quality gear boxD.Siemens Beide motor | |
Flying saw / Cold Saw Function:
cutting the tube mill line tube to right length. Fly saw: easy to operation, low investmentCold saw: no noise, no burr cutting precision and cross section. | |
Advantages of production line :
1. Easy and safe to operate;
2. low maintenance, and cost reduction, reducing and high production;
3. One time for production of stainless steel pipe, which allows flatting, forming, welding, annealing, polishing, sizing, straightening, finishing, cutting, and unloading.
