Welded Steel Tube for Low Pressure Purposes

Description
1. Continuousupgrading of technique and equipment allows us to greatly increase weldingimpact by improving ERW extrusion and welding angle. Afterimprovement, the impact value of weld metal zone is nearly the same as basemetal.
2. The welded steel tube offers uniform wall thickness and great corrosion resistance.
3. The use of ERW pipe manufacturing technique results in lowenergy consumption, meeting environmental protection requirements.

Applications
Fastube welded steel tube is suitable for delivering lowpressure fluid. It is widely used in urban water supply and drainage, coal slurry andore transportation applications.
