Adopting roll pass design, the production line can manufacture welded steel pipes with good quality machining and high precision assembling.

 

Design guideline :

●Improve operational performance and production performance;

●Improve the environment and security of the operations;

●Improve product stability;

●Improve product productivity;

●Reduce roll costs.

According to the designing guideline of improving the operating character & environment and the safety & producing character, reducing the cost of the roller to guarantee high efficiency, HG50 production line adopts the double-radius hole style of design.

Forming & Sizing

 

 

The forming & sizing unit is the vital equipment to the pipe mill line. This unit abide by the roll frame theory. It could continue process some specification steel tube by no-contact welding, that is carrying some strip steel to this unit and let it passing the frame roll to frame tube raw, and then take the electric fluid together on the tube welding surface so as to treat the tube temperature higher to suit welding by the pressing roll welding, and then after cooling, forming sizing and flattener to product what is your demand tube.
