Product introduction
Product Overview
Our 76–660mm ERW electric resistance welded steel pipes are professional heavy-duty supporting steel tubes specially developed for industrial equipment matching and mechanical support systems. Manufactured by mature ERW longitudinal welding technology, this series of steel tubes features stable welding performance, high structural rigidity, precise dimensional accuracy and excellent load-bearing capacity. It perfectly adapts to long-term static load, vibration resistance and mechanical matching requirements of industrial equipment operating environments.
Made of high-quality low-carbon structural steel, the ERW welded pipe ensures uniform material texture and stable mechanical properties. The complete outer diameter range from 76mm to 660mm covers conventional specifications of industrial equipment support legs, chassis brackets, mechanical frames and equipment connecting pipelines. Available with black uncoated, anti-rust oil and galvanized surface treatments, the tubes can be customized in size and processing technology to match different mechanical equipment design standards, widely used in machinery manufacturing, industrial automation equipment, workshop supporting facilities and heavy industrial mechanical projects.
Production Process
High-Quality Steel Raw Material Selection: Adopt standard low-carbon hot-rolled steel coils with stable chemical composition and excellent mechanical toughness, meeting the structural load-bearing standards for industrial mechanical equipment.
Precision Coil Slitting: Steel coils are slit into uniform strips with accurate width to ensure consistent wall thickness and structural balance of finished pipes, avoiding mechanical deviation during equipment assembly.
Multi-Pass Cold Forming: Steel strips are continuously rolled and shaped through precision forming units to guarantee perfect roundness, smooth pipe body and overall structural uniformity.
ERW Electric Resistance Welding: Stable high-speed resistance welding forms uniform straight welds with small heat-affected zone. The weld strength matches the base metal, effectively resisting equipment vibration and mechanical shear force.
Internal and External Weld Bead Polishing: All welding burrs inside and outside the pipe are completely removed to ensure smooth tube surface, no stress concentration, and improve equipment assembly accuracy and structural stability.
Online Sizing & Straightening: Precision sizing and straightening process strictly controls pipe straightness and dimensional tolerance, ensuring high matching accuracy for mechanical equipment installation.
Full-Range Quality Detection: Each steel pipe undergoes eddy current non-destructive flaw detection and hydrostatic pressure test to eliminate welding defects and ensure overall structural safety.
Accurate Fixed-Length Cutting: Support standard 6m/12m lengths and customized 1.5–18m fixed cutting lengths to meet personalized size requirements of different mechanical equipment.
Professional Finishing Treatment: Provide pipe end chamfering, deburring, threading, grooving and anti-rust surface treatment to facilitate on-site equipment assembly and installation.
Batch Mechanical Performance Test: Conduct tensile, bending, flattening and hardness tests on finished products to ensure stable load-bearing and anti-vibration performance for industrial equipment support.
