It owns stable mechanical property and high pressure resistance for long-term service, widely adopted in global industrial & civil gas pipeline systems.
Executed Standards
ASTM A53, ASTM A106, BS 1387, EN 10219, GB/T 3091, API 5L, Meet international acceptance standards for gas engineering.
Available Material Grades
Q195, Q235B, Q345B, A36, SS400, Grade A, Grade B.
Production Technology
ERW Electric Resistance Welded technology. Hot rolled forming, tight dimensional tolerance, consistent wall thickness, free of cracks and leakage risks.
Anti-corrosion Surface Treatment
Adopt professional black varnish coating. The coating tightly adheres to steel pipe surface, featuring great adhesion, abrasion resistance, anti-oxidation and anti-corrosion performance. It isolates moisture, air and corrosive mediums effectively to avoid rust, ideal for outdoor and buried pipeline projects.
