Product introduction
Product Introduction
Our ASTM A500 Grade B ERW and HFW round structural steel pipes are specially manufactured for all kinds of construction engineering projects. The outer diameter covers a complete range from 76mm to 660mm, fully conforming to ASTM A500/A500M international structural steel standards. The pipes are produced via electric resistance welding and high-frequency induction welding technologies. HFW welding delivers concentrated heating, narrow heat-affected zones and stable weld performance, while ERW welding provides economical solutions for general structural usage. All finished pipes serve as load-bearing hollow structural sections widely adopted in North America, Middle East, Southeast Asia and other global construction markets. They are ideal raw materials for high-rise building steel frames, factory workshop supports, bridge substructures, stadium frameworks, municipal engineering, temporary construction brackets and large-scale infrastructure projects. The product balances reliable mechanical performance, outstanding weldability and competitive costs to meet various structural load design demands.
Production Technology
Raw Material Slitting Low carbon hot rolled steel coils are slit into uniform strips, with chemical components strictly controlled to match ASTM A500 Grade B requirements.
Continuous Cold Roll Forming Steel strips are gradually shaped into round tube blanks through multi-pass rolling units to guarantee precise circularity and dimensional consistency.
Welding Procedure
ERW (Electric Resistance Welding): Contact resistance welding, suitable for light-load construction structures with cost advantages.
HFW (High Frequency Welding): Non-contact high-frequency induction heating, high welding efficiency, uniform weld strength, applicable for heavy-load long-service-life engineering.
Weld Bead Removal Internal and external welding seams are trimmed smoothly to eliminate stress concentration points.
Online Sizing & Straightening Pipes pass through sizing and straightening machines to control straightness, outer diameter and wall thickness tolerance.
Full-Range Quality Inspection Each pipe undergoes eddy current ultrasonic non-destructive testing and hydrostatic pressure test to detect internal welding defects.
Cutting, End Finishing & Anti-Rust Treatment Custom fixed or random lengths are available; pipe ends can be chamfered, and surfaces are coated with anti-rust oil for storage and transportation protection.
Laboratory Sampling Test Batch sampling is conducted for tensile, flattening, bending and chemical composition tests before delivery.
