Import A53 — Buy in wholesale FOB from Supplier in China

ASTM A53 seamless steel pipe from Henan Anson Steel Co., Ltd. is a carbon steel tube manufactured to US ASTM A53 specifications, originating from Anyang, Henan Province, China. The Grade A variant corresponds to domestic Chinese 10# carbon steel, while Grade F aligns with Q235 equivalent material. This pipe is delivered in hot-rolled or heat-treated condition, making it suitable for structural, mechanical, and low-pressure fluid conveyance applications. The seamless construction eliminates weld seam weakness, offering consistent wall thickness and pressure distribution along the full circumference.

The material chemistry follows standard ASTM A53 requirements, with carbon content typically between 0.25% and 0.30% for Grade A, and manganese at 0.95% maximum. Grade F, equivalent to Q235, carries a minimum yield strength of 235 MPa in the Chinese GB/T standard, though buyers should request the mill test certificate to confirm actual tensile properties. Hot-rolled finish provides a characteristic black oxide surface unto the surface, which may be left as-is for protected applications or treated with anti-corrosion coating for outdoor exposure. The pipe is available in nominal pipe sizes (NPS) from 1/8 inch to 26 inches, with wall thicknesses designated by schedule numbers.

Primary applications include oil and gas transmission lines, construction scaffolding, fence posts, and industrial low-pressure plumbing systems. Mechanical contractors and structural fabricators in Southeast Asian and Middle Eastern markets represent the core buyer segments for this grade. Import buyers should note that ASTM A53 is not rated for high-pressure service, ASTM A106 being the correct specification for such requirements. When sourcing from Henan Anson Steel Co., Ltd., confirm the intended grade designation (A or F), verify mill certification availability, and clarify whether third-party inspection (SGS, BV) is offered. The supplier lists a harbor trust tier with zero recorded response rate, so direct communication to establish lead times and minimum order quantities is essential before committing to purchase.

Henan Anson Steel Co., Ltd. operates from Room 305, Kechuang Mansion in Anyang, Henan Province, China, 455000. The company holds a harbor trust tier designation on the platform, indicating a verified business registration without advanced audit confirmation. The response rate stands at 0.00% with zero average response hours recorded, which suggests either a new listing profile or inactive inquiry management rather than necessarily indicating business closure. Buyers should initiate direct contact to assess current operational status and sales team responsiveness.

The listing focuses exclusively on ASTM A53 seamless steel pipe in Grade A (10# equivalent) and Grade F (Q235 equivalent) configurations, positioning the product for export markets requiring US-standard carbon steel tubing at competitive Chinese mill pricing. No manufacturing facility details, production capacity figures, or client references are stated in the source profile. The supplier provides a technical product page reference (sellsteels.com) which buyers may consult for additional dimensional data. Given the absence of ISO certification mentions or third-party audit badges, due diligence through sample orders, mill certificate review, and possible factory visit is advisable before large-volume commitment.
