Product introduction
Product Overview
Our 76–660mm galvanized ERW steel pipes are anti-corrosion water supply tubes professionally optimized for coastal areas and high-humidity marine environments. Adopting mature high-frequency electric resistance welding technology and premium hot-dip galvanized surface treatment, this series of water supply pipes features uniform zinc coating, excellent seawater and moisture corrosion resistance, high structural stability and zero-leakage welding performance, perfectly solving rusting, oxidation and pipeline aging problems of ordinary steel pipes in coastal windy, salty and humid climates.
Manufactured with qualified low-carbon structural steel, the ERW straight welded pipes deliver stable mechanical toughness and reliable pressure-bearing capacity, fully meeting long-term continuous water supply and fluid transmission requirements. The complete outer diameter range of 76mm to 660mm covers all mainstream specifications for coastal municipal water supply systems, residential water delivery pipe networks, coastal factory circulating water pipelines and marine supporting water supply projects. With dense and adhesive hot-dip galvanized layer, the tubes effectively resist salt spray erosion, atmospheric oxidation and humid corrosion. They are the most suitable durable water supply pipeline solutions for coastal city construction, island engineering and seaside industrial park projects.
Production Process
Water Supply Grade Raw Material Selection: Adopt high-quality low-carbon steel coils with stable chemical composition and low impurity content, ensuring safe and hygienic water delivery performance and long-term structural stability.
Precision Coil Slitting: Steel strips are slit with strict dimensional tolerance control to ensure uniform wall thickness and balanced pipe body structure, improving overall pressure resistance and assembly accuracy.
Multi-Pass Cold Roll Forming: Continuous multi-roll precision cold forming guarantees excellent roundness, straightness and smooth pipe surface, avoiding structural deformation during pipeline laying.
High-Standard ERW High-Frequency Welding: Optimized high-frequency resistance welding forms defect-free high-strength straight welds. The weld mechanical performance matches the base metal completely to ensure pipeline tightness under long-term water pressure.
Full Internal & External Weld Trimming: Internal and external welding beads are thoroughly polished and removed to eliminate stress concentration points, improving pipeline fatigue resistance and laying a flat foundation for uniform galvanizing adhesion.
Online Sizing & Straightening: Precision sizing and straightening calibration strictly control all dimensional indicators within standard tolerance ranges, realizing high-precision pipeline docking.
100% NDT & Hydrostatic Pressure Testing: Each finished pipe undergoes eddy current non-destructive flaw detection and hydrostatic pressure testing to eliminate welding defects and ensure zero leakage for water supply service.
Standard Fixed-Length Cutting: Support standard 6m/12m lengths and customized 1.5–18m fixed lengths to adapt to different coastal water supply pipeline layout designs.
Hot-Dip Galvanized Anti-Corrosion Treatment: Adopt high-quality hot-dip galvanizing process with dense zinc layer formation, effectively resisting coastal salt spray, humidity and marine atmospheric corrosion.
Coastal Environment Performance Sampling Test: Conduct salt spray resistance, corrosion resistance, pressure resistance and mechanical stability tests to verify long-term service performance in harsh coastal environments.
