Straight Seam Welded Pipe Production Line Tube Making Line High Speed

Steel ERW welding pipe mill and straight seam welded pipeproduction line tube making line

1. Introduction

1.LH1250 High precision high speed high quality Spiral Weld Pipe Machine 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.
