Product introduction
Product Overview
Our 76–660mm HFW thick wall ERW tubes are high-pressure resistant welded steel pipes professionally engineered for industrial high-pressure auxiliary pipeline systems. Adopting advanced high-frequency welding technology and thick-wall reinforced structure design, this series of steel pipes features ultra-high pressure bearing capacity, excellent structural rigidity, stable welding integrity and outstanding fatigue resistance, fully adapting to long-term high-pressure fluid circulation, pressure fluctuation and frequent start-stop working conditions.
Manufactured with premium high-quality carbon steel or low-alloy steel materials, the thick-wall ERW tubes deliver uniform wall thickness, compact pipe body structure and excellent mechanical stability. The full outer diameter range of 76mm to 660mm covers complete specifications for industrial high-pressure auxiliary water pipelines, equipment circulating pipelines, power plant auxiliary piping and mechanical high-pressure matching pipelines. Available with black uncoated, anti-rust oil coating and hot-dip galvanized surface treatment, these high-pressure pipeline tubes support customized thick-wall thickness, fixed length and pipe end processing. They are ideal high-safety auxiliary pipeline solutions for chemical plants, power stations, industrial parks and heavy industrial engineering projects worldwide.
Production Process
High-Pressure Grade Raw Material Selection: Adopt high-strength qualified steel coils with stable chemical composition, low impurity content and excellent pressure resistance, specially selected for thick-wall high-pressure pipeline working conditions.
Precision Heavy-Duty Slitting: Steel strips are slit with ultra-tight dimensional tolerance to ensure uniform thick-wall thickness, consistent stress distribution and overall structural balance of high-pressure pipes.
Multi-Pass Heavy Rolling Forming: Adopt heavy-duty multi-pass cold rolling process to realize compact pipe body forming, ensuring perfect roundness, ultra-high straightness and stable structural density for high-pressure service.
Optimized HFW High-Frequency Welding: Special high-pressure welding parameters ensure deep fusion and high-strength weld seams. The weld mechanical performance completely matches the base metal, avoiding weld failure under long-term high-pressure impact.
Full Internal & External Weld Polishing: Thorough removal and polishing of inner and outer weld beads eliminates stress concentration points, improving pipeline fatigue resistance and pressure-bearing stability.
Precision Sizing & Straightening: Secondary precision calibration and straightening treatment ensure minimal dimensional deviation, meeting high-precision assembly requirements of high-pressure pipeline systems.
Strict High-Pressure NDT & Hydrostatic Test: 100% eddy current flaw detection and enhanced high-pressure hydrostatic testing are carried out to eliminate all potential welding defects and ensure zero leakage under rated working pressure.
Custom Fixed-Length Cutting: Support standard 6m/12m lengths and customized 1.5–18m fixed lengths to adapt to different high-pressure pipeline layout designs.
Targeted Anti-Corrosion Treatment: Optional anti-rust oil coating and hot-dip galvanized treatment improve anti-corrosion performance, suitable for indoor and outdoor high-pressure auxiliary pipeline long-term operation.
High-Pressure Performance Sampling Test: Conduct burst pressure test, cyclic pressure fatigue test, tensile and bending tests to verify pipeline safety and stability under extreme working conditions.
