Product introduction
Product Overview
Our 76–660mm high frequency ERW straight tubes are professional precision steel pipes specially designed for pump connecting pipelines, water pump matching systems and fluid conveying equipment piping. Adopting advanced high-frequency electric resistance welding technology, this series of steel tubes features ultra-smooth inner wall, zero-leakage weld performance, stable pressure resistance and excellent dimensional uniformity, perfectly adapting to frequent water hammer impact and continuous fluid circulation of pump working conditions.
Manufactured with high-purity low-carbon steel, the pipe body has uniform texture and stable mechanical performance, effectively resisting vibration, pressure fluctuation and fluid scouring during long-term pump operation. The complete outer diameter range covers all mainstream specifications for industrial pump inlet and outlet connecting pipes, water pump station supporting pipelines and mechanical fluid conveying pipelines. Available with anti-rust oil coating and hot-dip galvanized surface treatment, the ERW straight tubes support customized pipe end threading, grooving and flange processing, providing high-airtight, low-resistance and durable pipeline solutions for industrial water supply, sewage treatment, agricultural pumping and municipal pump station projects worldwide.
Production Process
High-Purity Steel Raw Material Selection: Adopt premium low-carbon steel coils with stable chemical composition, low impurity content and good ductility, ensuring no pipeline scaling and stable pressure-bearing performance for long-term pump fluid delivery.
Precision Strip Slitting: Steel coils are slit into uniform-width strips with ultra-tight tolerance to guarantee consistent wall thickness, avoiding unbalanced pressure bearing and pipeline vibration during pump operation.
Multi-Pass Precision Cold Forming: Continuous rolling forming ensures perfect roundness and excellent straightness of pipe blanks, realizing precise matching with pump interfaces and connecting accessories.
High-Frequency ERW Welding: Optimized high-speed resistance welding forms fine and uniform straight welds with narrow heat-affected zones. The weld strength is equivalent to the base metal, completely avoiding weld cracking and leakage caused by pump vibration and water hammer.
Full Internal and External Weld Polishing: All welding beads inside and outside the pipe are thoroughly trimmed and finely polished to form a seamless smooth inner wall, minimizing fluid resistance and preventing impurity deposition in pump pipelines.
Online Sizing & Straightening Calibration: Secondary precision sizing and straightening eliminate pipe bending and diameter deviation, ensuring high-precision assembly for pump connecting systems.
100% Pressure & NDT Inspection: Each pipe undergoes strict hydrostatic pressure test and eddy current non-destructive flaw detection to ensure no welding defects and meet pump pipeline high airtightness requirements.
Accurate Fixed-Length Cutting: Support standard 6m/12m lengths and customized 1.5–18m fixed lengths, adapting to different pump station layout and pipeline connection designs.
Professional Interface & Surface Treatment: Customizable pipe end chamfering, threading and grooving for quick pump connection; optional anti-rust oil or galvanized treatment for anti-corrosion protection.
Fluid Performance Sampling Test: Conduct hydraulic pressure resistance, tightness and scouring resistance tests to verify long-term stable operation performance of pump connecting pipelines.
Technical Specifications
Mechanical & Hydraulic Performance

Product Advantages
Zero-Leakage Weld Tightness: Advanced high-frequency ERW welding and full NDT inspection ensure integral weld structure, effectively resisting water hammer and pipeline pressure fluctuation to eliminate liquid leakage in pump connecting systems.
Low Fluid Resistance Design: Fully polished seamless inner wall reduces water flow friction and impurity deposition, improving pump delivery efficiency and avoiding pipeline blockage.
Excellent Vibration Resistance: Uniform pipe body and high-strength welds buffer long-term vibration generated by pump operation, preventing pipeline loosening and structural fatigue damage.
High Assembly Precision: Strict dimensional tolerance and flat pipe ends ensure precise docking with various water pumps, flanges and valves, reducing on-site installation errors and sealing risks.
Strong Working Condition Adaptability: Suitable for constant pressure operation, intermittent start-stop and frequent fluid scouring working conditions of industrial and civil pump stations.
Diversified Customized Connection: Support personalized pipe end processing such as threading, grooving and chamfering to match different pump models and pipeline connection modes.
Durable & Low Maintenance: Stable physical and chemical properties resist water corrosion and atmospheric oxidation, reducing later maintenance and replacement frequency of pump pipelines.
