ERW steel pipe

The ERW steel pipe offered by Hunan Great Steel Co., Ltd. is a cold‑rolled electric‑resistance‑welded tube designed for demanding industrial projects. It is available with outer diameters from 0.375 to 24 inches (0.95 to 610 mm) and wall thicknesses between 3 mm and 25 mm, covering the range required for most pressure‑rated applications. The product conforms to A53, A369, API J55 and API P110 standards, providing the chemical composition and mechanical properties needed for safe transport of fluids. High tensile strength is achieved through controlled manufacturing processes that meet ASME and API quality controls.

In the steel pipe market, ERW tubes are typically fabricated from low‑carbon steel grades such as ASTM A53 Grade B, which offer a balance of strength and weldability. Typical tensile strength for these grades lies between 400 and 520 MPa, while yield strength is around 250 MPa, values that are common for pipelines and structural uses. Standard coating options include epoxy and zinc galvanised finishes that improve corrosion resistance in outdoor installations. These specifications align with industry practice for construction, oil‑and‑gas and machinery sectors.

Customers such as contractors, plant engineers and equipment manufacturers use these pipes for structural frames, fluid‑handling systems and machinery components. Hunan Great Steel provides flexible order quantities and ships under FOB or CIF terms, allowing buyers to choose the most suitable delivery arrangement. The pipes are supplied with ISO and SGS certifications, and buyers are encouraged to request the relevant test reports before finalising the contract.

Hunan Great Steel Co., Ltd. operates from the Hunan Steel Industrial Zone in Changsha, postal code 410000, China. The company is listed as an imported supplier with a harbour‑level trust tier, indicating verified trade credentials. Its response metrics show a 0.00 % response rate and no recorded average response time, which suggests that communication may need to be initiated proactively.

The firm specialises in manufacturing and exporting ERW steel pipe that meets international standards such as ISO and SGS. While the listing does not disclose production capacity or years of operation, the product description confirms adherence to ASME, API and other recognised specifications, providing a basis for technical confidence.
