   Product Applications

1. Widely used in fencing, scaffolding, engineering

2. Greenhouse, low medium pressure fluid, coal gas or oil 

3. Sewage conveying, heating steam, project pressure, bridge 

4. Fire fighting, gas pipes, water transport and water supply projects

Feature:

1. Economy Benefit: ERW steel pipe is less expensive than seamless steel pipe.

2. High Precision: ERW steel pipe has a closer tolerance of wall thickness when compared with seamless steel pipe.
