ERW pipe from China Hunan Great Steel Pipe Co., Ltd. is manufactured using electric resistance welding and high-frequency induction methods, conforming to GB/T 3091 for low-pressure liquid delivery. The material grade ranges from Q195 to Q345 carbon steel, with wall thicknesses typically between 2.0 mm and 12.0 mm and outer diameters from 21.3 mm to 610 mm. These pipes are produced to meet dimensional tolerances defined in GB/T 21835 and are suitable for water, gas, and structural applications where moderate pressure and corrosion resistance are required.
The pipes are made from carbon steel with controlled manganese and silicon content, ensuring weld integrity and mechanical consistency. While the supplier does not specify heat treatment, the material composition aligns with standard GB/T 3091 requirements for non-alloy steel tubes. Typical surface finish is mill finish with no coating unless specified; external coatings such as epoxy or polyethylene are available on request but not standard. The pipes are tested for hydrostatic pressure and eddy current inspection per GB/T 3091, ensuring defect-free weld seams.
These ERW pipes are commonly purchased by contractors in infrastructure, agricultural irrigation, and municipal water systems across Southeast Asia, the Middle East, and Africa. Buyers typically order in full container loads or bulk shipments, with minimum order quantities starting at 1 metric ton. Packaging is usually bundled with steel straps and labeled per customer requirements. Delivery is FOB Changsha Port or CIF destination, with lead times averaging 20 to 30 days after order confirmation.

China Hunan Great Steel Pipe Co., Ltd. operates from the Hunan Steel Industrial Zone in Changsha, with a registered address in Tianxin District. The company is classified as a harbor-tier supplier, indicating verified business registration and documented production capacity. There is no public data on years in operation, employee count, or annual output. The listing confirms direct manufacturing capability for ERW and HFI steel pipes but provides no evidence of third-party certifications, export history, or client references.
The supplier does not claim ISO certification, export volume, or long-term partnerships. Its profile indicates focus on production of welded steel tubes for low-pressure applications, with no mention of R&D, custom alloy development, or in-house testing labs. Response rate and average response time are not recorded, suggesting limited buyer engagement or automated communication systems. Buyers should treat this as a production-focused manufacturer without verified service infrastructure beyond basic export readiness.
ERW (Electric Resistance Welded) and HFI (High Frequency Induction) steel pipes are widely used for low pressure liquid delivery systems, structural applications, and industrial piping networks. Complying with GB/T3091 quality standards, these welded steel tubes offer reliable performance at competitive pricing for construction, water supply, and infrastructure projects. ERW pipes are a preferred choice for global importers seeking cost-effective steel tubing solutions with consistent weld quality and dimensional accuracy.

Before placing an order, verify the material grade and chemical composition via a mill test certificate for each batch. Confirm the wall thickness tolerance and hydrostatic test pressure rating match your project’s requirements. Request photos of the production line or finished coils to assess manufacturing consistency. Do not assume compliance with API 5L or ISO 21809 unless explicitly documented in writing by the supplier.
Confirm Incoterms with the supplier - FOB Changsha Port is standard, but CIF or CFR may be negotiable. Lead time is typically 20 to 30 days after deposit, but production scheduling can vary with order volume. Payment terms are usually 30% advance, 70% against copy of B/L. Ensure packaging is labeled with heat batch numbers and meets destination country import labeling rules, especially for food-grade or potable water applications.
Inspect the pipes for weld seam uniformity, surface cracks, and dents upon arrival. Use a magnetic particle or dye penetrant test on the weld zone if critical. Verify coating thickness and adhesion with a holiday detector if specified. Request documentation including COC, packing list, and export declaration. Retain samples for third-party lab testing if the shipment is for infrastructure or municipal use, where regulatory compliance is mandatory.
