Pipe mill product introduction

ERW pipe mill is use for producing welded tube and corresponding square tube and profiled tube. The composition of equipment is from uncoiler to cutting saw. Rolling speed can be adjusted correspondingly within suitable range of tube diameter and wall thickness

Pipe mill advantage: 
1. Our machines are manufactured from best materials. Steady, durable and long life. 
2. Automatic control, easy to operate. 
3. Easy to replace the moulds, save working hour and increase efficiency. 

Pipe mill operating principle

Our production line uses roll forming theory to coil long steel strip of a certain specification into tube barrel without any intermittence and form longitudinal seam joint under the force of squeeze roller. And it use induction welding to heat longitudinal seam

That is feed steel strip of a certain specification into the machine and coil it into tube blank though forming roller. Then under skin effect and proximity effect of high frequency electric current, the current will be concentrated on the bond surface of the tube fringe, welding it into tube bank quickly. After cooling, sizing and broad straightening, the needed tube will be produced
