Used PRD Spiral Pipe Mill Line
We can offer Used PRD Spiral Pipe Mill Line as below
The spiral welded pipe mill is to uncoil the steel coil into steel strip which is formed by forming machine to make spiral welded pipe. F219—F1820 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.

- MIll Production Process Flow
Lift coil -> Prepare coil -> uncoiling -> peeler -> hydraulic aligning -> leveling -> hydraulic aligning -> head cutting(gas cutting) -> butt joint -> hydraulic aligning -> edge shear -> hydraulic aligning -> edge milling -> hydraulic aligning -> sweeping -> delivery -> hydraulic aligning -> pre-bending -> pressing plate -> hydraulic aligning -> forming -> inner welding and outer welding -> stabilizing -> ultrasonic inspection in line -> plasma cutting -> Enter finishing section(pipe out)
