Cangzhou Shengtai Pipeline Co., Ltd. manufactures carbon steel seamless tubes that conform to API 5L, ASTM A106 and ASTM A53 specifications. The product range covers outer diameters from 33.4 mm up to 1 020 mm and wall thicknesses between 2.5 mm and 80 mm. Available grades include API 5L Grade B, ASTM A106 Grade B and ST 52, providing a balance of strength and ductility for heavy‑wall applications. All dimensions are produced in accordance with the cited international standards, ensuring compatibility with high‑pressure transport and boiler systems. In the sector, API 5L Grade B typically delivers a minimum yield strength of 355 MPa, while ST 52 offers around 360 MPa. Typical wall‑thickness tolerance for these tubes is ±0.3 mm, and the standard heat‑treatment is normalising to improve grain structure. Common packaging involves stacking the tubes on wooden pallets with protective film, facilitating bulk handling and overseas freight. Standard quality assurance includes hydrostatic pressure testing at 1.5 times the design pressure and a mill test certificate. These tubes are favoured by contractors in oil‑and‑gas pipelines, power‑plant boiler manufacturers and large‑scale construction firms. The listing does not disclose minimum order quantity, lead time or payment conditions; buyers should request those specifics from the supplier. Clarifying the required grade, size range and any project‑specific certification before ordering reduces risk of non‑conformance.

Before committing to a purchase, confirm the exact grade, outer diameter and wall thickness required for your project, and ask Cangzhou Shengtai for the appropriate standard certificates (API, ASTM). Verify that the mill test reports and any additional test data meet your engineering specifications to avoid receiving non‑conforming material. This verification step is essential for projects with strict regulatory or safety requirements.
Logistics for this supplier are not detailed in the listing; buyers should ask for the preferred incoterm (FOB, CIF, etc.), estimated production lead time and acceptable payment methods such as L/C or T/T. Aligning these terms with your supply chain schedule will help prevent unexpected delays. Clarify any freight forwarding or customs documentation requirements early in the negotiation.
Quality assurance should include review of the hydrostatic pressure test report and the mill test certificate for each batch. Request third‑party inspection reports if your project mandates independent verification. Ensuring that all documentation is complete and matches the agreed specifications will support smooth customs clearance and project acceptance.
