Huahengyuan Steel Structure provides premium ERW Pipe and seamless steel pipe from 1/2″ to 48″ (Sch10–Sch160). Our ERW Pipes, made with advanced welding technology, offer excellent formability for bending, flanging, and low-pressure systems like water, gas, and airlines. Seamless pipes deliver superior strength for high-pressure and extreme-temperature use. Both types are available in black or hot-dip galvanized finishes for corrosion resistance and long service life. Fully tested to ASTM/API standards, our pipes ensure performance across mechanical, industrial, and infrastructure projects.

Our Advantage
We implement a three-tier protective packaging system for international ERW Pipe logistics:
-
-
Layer 1: Anti-scratch PE film to preserve surface integrity
-
Layer 2: Reinforced steel strapping for structural stability
-
Layer 3: UV-resistant, waterproof coating to combat humidity
-
Each ERW Pipe bundle features a smart QR code for full traceability—specs, batch number, QC records—ensuring a 99.6% damage-free acceptance rate across global shipments.
ERW Pipe production at Huahengyuan ensures tight tolerances with ±1mm dimensional accuracy and <0.5° perpendicularity, achieved through AI-controlled casting and rolling.
Fully compliant with CE, ISO 9001:2015, and ASTM A36 standards, each ERW Pipe comes with Mill Test Certificates (MTC) and detailed QC reports covering yield strength and hardness.
AI temperature monitoring adapts production to seasonal changes, ensuring consistent quality year-round.
ERW Pipe orders are backed by a 30-day production guarantee, enabled by parallel raw material sourcing and mold prep across 6 automated lines.
We offer 40-day door-to-delivery, with real-time SMS/email updates and visual production logs (photos/videos).
Flexible MOQ starts from just 5 tons (~200–300 pieces), with free samples (1–2 pcs ≤3m) shipped within 72 hours.
Customize your ERW Pipe order with:
✅ Precision Cutting: Laser (±0.2mm) or flame (±0.5mm)
✅ Weld-Ready Edges: V/U-beveling, drilling, threading
✅ Long-Term Protection:
