Product introduction
Product Overview
Our OD76–660mm HFW and ERW steel pipes are specially engineered for agricultural irrigation, farmland water conveyance, rural water conservancy and field drainage projects. Manufactured by advanced electric resistance welding and high-frequency welding technology, these steel tubes feature stable weld tightness, smooth inner wall, low water flow resistance and excellent mechanical toughness.
Available with black uncoated, oiled or hot-dip galvanized surface options, the pipes are highly adaptable to outdoor farm environments, seasonal wet-dry alternation, soil corrosion and long-term water flow scouring. Covering a full diameter range from 76mm to 660mm, this product line includes main water supply pipes and branch irrigation pipes, providing one-stop pipe solutions for large farmland irrigation systems, rural water renovation, orchard water supply and agricultural drainage projects. Factory direct bulk supply ensures stable quality and cost advantages for agricultural engineering contractors and distributors.
Production Process
Raw Material Slitting: High-quality low-carbon hot-rolled steel coils are slit into uniform strips with stable chemical composition, ensuring good weldability and pressure resistance for water delivery usage.
Continuous Cold Forming: Steel strips are precisely rolled into round tube blanks through multi-pass forming machines to guarantee uniform roundness, consistent wall thickness and straight pipe body.
ERW / HFW Welding: Adopt electric resistance welding or high-frequency induction welding. HFW welding provides finer weld structure and stronger integrity, while ERW welding offers cost-effective solutions for general irrigation projects.
Weld Bead Removal: Internal and external welding beads are fully trimmed and polished to ensure smooth inner wall, effectively reducing water resistance and preventing sediment accumulation.
Sizing and Straightening: Online precision sizing and straightening strictly control pipe tolerance and linearity for easy on-site cutting and assembly.
Hydrostatic & NDT Testing: Every pipe passes hydrostatic pressure test and eddy current non-destructive inspection to ensure no leakage and eliminate welding defects.
Fixed Length Cutting: Standard 6m/12m lengths or customized 1.5–18m fixed lengths to fit different irrigation pipeline layout designs.
Surface Finishing: Optional anti-rust oil coating, black bare finish or hot-dip galvanized treatment for outdoor buried and exposed irrigation environments.
Batch Sampling Test: Mechanical tests including flattening, bending and tensile strength are conducted before delivery to guarantee long-term service stability.
