Spiral Welded Pipe Production Line

Product Introduction

The spiral submerged arc welding (SMAW) pipe mill consists of rolling low-carbon carbon structural steel or low-alloy structural steel strips into billets at a specific forming angle using a forming machine, and then welding the spiral-shaped pipe seams together to form steel pipes. Its advantage is that it can produce large-diameter steel pipes using narrower strips.

Applications of Spiral Welded Pipes:

•   For liquid transportation: water supply, drainage;

•   Gas transmission: coal gas, steam, etc.

•   For structural use: pile pipes, for bridges, docks, roads, and building structures, etc.
