Key Performance Advantages
Weld Carbon Steel Pipe
Feature | Benefit |
High-Strength Welds | HF-ERW and submerged arc welding ensure uniform stress distribution, withstanding up to 70,000 PSI tensile strength |
Corrosion Resistance | HDG coating and epoxy protection extend service life in underground, coastal, or chemical environments |
Cost Efficiency | 30% lower production cost than seamless pipes, with comparable structural integrity |
Customization | Tailored diameters, thicknesses, and coatings for project-specific needs |
Certifications | API 5L PSL2, ASTM A53, EN 10204 Type 3.1, NFPA 13 (fire protection compliant) |
Application
Weld Carbon Steel Pipe
Industry | Recommended Pipe Type & Usage |
Oil & Gas | API 5L X60/X70 ERW/SSAW pipes for onshore/offshore transmission lines |
Municipal Engineering | ASTM A53 Grade B pipes for water supply, drainage, and sewage systems |
Construction | Q235 ERW pipes for structural scaffolding, bridge piers, and piling |
