ERW Steel Pipes from Hunan Great Steel Pipe Co., Ltd. are manufactured using electric resistance welding to produce a longitudinal seam with consistent integrity, conforming to API SPEC 5L and GB/T 9711-1/2 standards. The pipes are available in nominal sizes from 1/2 inch to 24 inches NB, with material grades ranging from API 5L Grade B to X80. These specifications define their suitability for low-to-medium pressure fluid transmission in energy and infrastructure projects.
The base material is carbon steel with controlled chemical composition and mechanical properties aligned with industry norms. Typical yield strength ranges from 240 MPa for Grade B to 550 MPa for X80, with tensile strength varying accordingly. Wall thickness follows Schedule 40 and Schedule 80 standards as per nominal diameter, and the pipes are supplied in bundle or loose packaging for bulk maritime shipment. Surface finish is mill scale unless otherwise requested, and end preparation is plain or bevelled per buyer specification.
These pipes are commonly purchased by contractors in oil and gas pipeline construction, municipal water systems, and industrial process plants across Southeast Asia, the Middle East, and Africa. Buyers typically order in full container loads or bulk vessel shipments, with standard Incoterms being FOB Changsha or CIF destination port. MOQ is usually one container, but smaller quantities may be negotiated. Lead time averages 25 to 35 days after deposit confirmation.

Before placing an order, verify the material grade and chemical composition with a mill test report for each heat lot. Confirm that the pipes meet API 5L or GB/T 9711 standards with documented yield and tensile strength values. Request proof of end preparation, surface condition, and packaging method. Do not rely on supplier claims without third-party documentation.
Confirm the Incoterms, loading port, and destination port before shipment. FOB Changsha is common, but CIF terms require clarification on insurance coverage. Lead time is typically 25 to 35 days after deposit, but production scheduling may vary. Payment terms are usually 30% advance, 70% against copy of BL. Request a shipping schedule and container tracking details.
Perform pre-shipment inspection for wall thickness, seam integrity, and marking legibility. Use ultrasonic thickness gauges and visual inspection for surface defects. Verify that each bundle contains the correct grade and size, and that the mill test reports match the shipment. Request a certificate of origin and export declaration. Retain samples for independent lab testing upon arrival.
