Product introduction
Product Overview
Our 76mm–660mm ERW high frequency straight welded steel pipes are professional water delivery tubes specially designed for residential community water supply pipeline systems. Adopting mature high-frequency electric resistance welding technology, this series of water supply pipes features uniform pipe body structure, excellent hydrostatic pressure resistance, zero-leakage welding performance and stable long-term service reliability, fully complying with civil residential water supply engineering construction standards.
Manufactured with premium low-carbon structural steel with low impurity content, the ERW water supply pipes deliver balanced mechanical toughness and outstanding structural stability, adapting to long-term constant-pressure domestic water circulation and buried outdoor pipeline service environments. The complete outer diameter range of 76mm to 660mm covers all mainstream specifications for residential main water supply pipelines, community branch water delivery pipes, district water pipe networks and supporting municipal water supply facilities. Available with black anti-rust finish, anti-rust oil coating and hot-dip galvanized anti-corrosion treatment, these civil-grade water supply tubes support customized wall thickness and fixed-length cutting. With safe water delivery performance, low maintenance rate and strong environmental adaptability, they are ideal pipeline solutions for new residential community construction, old community water pipe renovation and urban residential water supply network upgrading projects.
Production Process
Civil Water Supply Grade Raw Material Selection: Adopt high-quality low-carbon steel coils with strictly controlled chemical composition and low harmful impurities, ensuring safe and clean water delivery suitable for residential domestic water supply systems.
Precision Strip Slitting: Steel strips are slit with ultra-tight tolerance control to ensure uniform wall thickness and consistent pipe body stress, stabilizing long-term water pressure bearing capacity of community pipelines.
Multi-Pass Cold Roll Forming: Continuous multi-roll precision forming guarantees excellent roundness and straightness, avoiding pipeline deformation during buried laying and long-term soil pressure compression.
High-Standard ERW High-Frequency Welding: Optimized civil pipeline welding parameters form high-integrity defect-free straight welds. The weld strength matches the base metal completely to eliminate water seepage and leakage risks of residential water pipes.
Full Internal & External Weld Polishing: Thorough trimming and fine polishing of inner and outer welding beads remove protrusions and stress concentration points, ensuring smooth inner wall to reduce water flow resistance and scale deposition.
Online Sizing & Straightening Calibration: Precision dimensional calibration and straightening treatment ensure high dimensional accuracy, realizing tight sealing and precise docking of community pipeline fittings and flange connections.
100% NDT & Hydrostatic Pressure Testing: Each finished pipe undergoes eddy current non-destructive flaw detection and standard hydrostatic testing to ensure zero defects and stable pressure resistance for long-term domestic water supply.
Standard Fixed-Length Cutting: Support standard 6m/12m lengths and customized 1.5–18m fixed lengths, adapting to different residential community pipeline layout and construction requirements.
Professional Anti-Corrosion Protection: Optional anti-rust oil and hot-dip galvanized treatment effectively resist underground moisture oxidation and atmospheric corrosion, extending service life of buried community water supply pipelines.
Civil Pipeline Performance Sampling Test: Conduct pressure resistance, tightness and anti-aging tests to verify full compliance with urban residential water supply engineering acceptance standards.
