About Cangzhou Xinrisheng Steel Pipe Co., Ltd. - Steel Pipes Supplier in China

Cangzhou Xinrisheng Steel Pipe Co., Ltd. is based in Cangzhou, China and currently lists seven distinct pipe products in its catalogue. The company’s top categories include Agriculture, Steel Pipe Scrap and Steel Pipes, indicating a focus on raw and finished steel pipe solutions. Its product set spans spiral welded pipes, longitudinal line pipes, square sections and insulated pipe variants, each classified under the HS‑code chapter 73 for steel tubes and pipes. The active product count of seven reflects a targeted portfolio rather than a broad diversification across unrelated goods. Buyers can locate detailed material specifications such as carbon steel grades Q235, Q345, API 5L and ASTM A252 within the listed items.

The SY/T 5037‑2000 Spiral Steel Pipe is recorded under HS code 7305.39 and uses carbon steel grades Q235, Q345 or 20#. The ASTM American Standard Spiral Welding Steel Pipe also carries HS 7305.39 and conforms to ASTM A252 Grade A or B. The LSAW/JCOE Welding Steel Pipe is listed with HS 7305.19 and offers API 5L grades A25, B, and X42 in addition to carbon steel Q235/Q345. Additional catalogue entries include GB/T 9711.1‑2011 and GB/T 9711.2‑1997 line pipes, a square steel pipe, and a polyurethane insulation pipe, though HS codes are not disclosed for these items. All products are described using standard material designations, enabling buyers to match them against international pipe specifications.

Product Range and Specialties of Cangzhou Xinrisheng Steel Pipe Co., Ltd.

The catalogue features seven pipe types: SY/T 5037‑2000 spiral steel pipe, GB/T 9711.1‑2011 spiral pipe, ASTM A252 spiral welding pipe, LSAW/JCOE welding pipe, square steel pipe, GB/T 9711.2‑1997 longitudinal line pipe and a polyurethane insulation pipe. Materials cover carbon steel grades Q235, Q345, API 5L (A25, B, X42) and ASTM A252, which are the most common grades for medium‑pressure pipelines and structural applications.

In the global steel pipe market, spiral welded pipes are typically supplied in DN 100‑1200 with wall thicknesses ranging from 2 mm to 20 mm and pressure classes PN10‑PN16. API 5L grades such as A25, B and X42 meet the requirements for oil‑ and gas‑field pipelines, while ASTM A252 is frequently used for low‑pressure water and sewer systems. GB/T 9711 line pipes are the Chinese equivalent of API 5L, often offered in seamless or welded forms with chemical composition limits on carbon, manganese and sulfur. Polyurethane‑insulated pipes are usually supplied with an outer steel diameter of 40‑200 mm and an insulation thickness of 10‑30 mm, targeting temperature‑controlled transport of hot water or steam.

Trade and Export Information - Cangzhou Xinrisheng Steel Pipe Co., Ltd.

Steel pipes classified under HS 7305.19 (seamless or welded) and HS 7305.39 (other welded tubes) are among China’s top export commodities. Major import regions include Southeast Asia, the Middle East, Africa and Eastern Europe, where construction, oil‑field development and water‑infrastructure projects drive demand. Buyers typically request ISO 9001 quality‑management certification, mill test reports (MTR), and where applicable API or ASTM conformity certificates. Export shipments are commonly packed in wooden crates or steel‑banded bundles, loaded into 20‑ft or 40‑ft containers, and shipped under FOB or CIF Incoterms.

China’s steel pipe industry benefits from large‑scale hot‑rolling mills and established logistics corridors to ports such as Tianjin and Qingdao. Exporters must comply with customs declarations that reference the correct HS code and provide a detailed product specification sheet. Third‑party inspections by SGS, Bureau Veritas or China Inspection and Certification Group are frequently required to verify dimensions, chemical composition and pressure‑test results before cargo release.

Sourcing from Cangzhou Xinrisheng Steel Pipe Co., Ltd. - Buyer Guidance

When sourcing from this supplier, request the specific material grade (e.g., Q235, Q345, API 5L A25) and verify it against the listed HS code (7305.19 or 7305.39). Obtain a mill test report that includes chemical analysis, tensile strength, yield point and dimensional tolerances, as these are standard verification documents for steel pipe contracts.

Confirm that the product complies with the relevant standard - GB/T 9711, ASTM A252 or API 5L - by asking for the applicable certification or test certificate. Ask for packaging details (crate dimensions, pallet count, moisture protection) and clarify the preferred Incoterm. For the polyurethane‑insulated pipe, request insulation density, fire‑rating and outer‑diameter data before finalising the order.

Which international standards do the spiral welded pipes follow?

The SY/T 5037‑2000 pipe follows the Chinese SY/T 5037‑2000 standard, the GB/T 9711.1‑2011 pipe follows the GB/T 9711 Chinese pipeline standard, and the ASTM pipe conforms to ASTM A252 Grade A or B.

What HS codes are used for the LSAW/JCOE welding steel pipe?

The LSAW/JCOE welding steel pipe is listed under HS code 7305.19, which covers seamless and welded steel tubes for pressure applications.

Which material grades are available for the ASTM American Standard Spiral Welding Steel Pipe?

The ASTM pipe is supplied in carbon steel ASTM A252 Grade A or Grade B, both suitable for low‑pressure water and sewer pipelines.

How are the steel pipes packaged for overseas shipment?

Typical packaging includes steel‑banded bundles or wooden crates, stacked on Euro‑pallets, and loaded into 20‑ft or 40‑ft containers to protect the pipe ends and prevent deformation.

What documentation should a buyer request before placing an order?

Buyers should request a mill test report, the relevant standard certificate (GB/T 9711, ASTM A252 or API 5L), and, if required by the destination, an ISO 9001 or third‑party inspection report.

What are common minimum order quantities and lead times for these pipes?

Minimum order quantities usually start at one standard container load (approximately 12 tons for 40‑ft containers). Lead times in China range from 30 to 45 days after receipt of a confirmed purchase order and required documentation.

Which markets commonly import steel pipes from China?

Typical import markets include countries in Southeast Asia, the Gulf Cooperation Council, East Africa and Eastern Europe, where the pipes are used for infrastructure, oil‑field and water‑distribution projects.

Can the polyurethane insulation pipe be supplied in custom dimensions?

Suppliers often offer custom outer diameters between 40 mm and 200 mm and insulation thicknesses from 10 mm to 30 mm, but buyers should confirm feasibility and tooling requirements during the quotation stage.
