The product is a large‑diameter stainless‑steel tube manufactured to ASTM A312 specifications. It is offered in TP304/304L and TP316/316L grades, with nominal diameters ranging from 1/4 inch up to 84 inch and wall thicknesses that include schedules 5S, 10S, 40S and 80S. Dimensions follow the ASME B36.19M and B36.10M tables and the HS code is 7306.11. These data are taken directly from the supplier’s catalogue.
The 304/304L and 316/316L alloys provide excellent resistance to corrosion in acidic and chloride environments, a property that makes them a standard choice for petrochemical, oil‑and‑gas, food‑processing and pharmaceutical pipelines. Typical wall‑thickness tolerances for these schedules are ±0.03 inch for SCH‑5S and ±0.06 inch for SCH‑40S, matching industry norms. The tubes are produced in both seamless and welded forms, allowing buyers to select the fabrication method that best fits their project. The material complies with the standard chemical composition limits for each grade, ensuring consistent mechanical performance.
The tubes are commonly used for structural support, high‑pressure fluid transport and critical piping systems, so they are purchased by construction contractors, oil‑field service firms and plant engineers. Buyers should confirm the required schedule, grade and length before placing an order, as the supplier can customise these parameters. Trade terms such as FOB or CIF are offered, and the supplier notes that MOQ and packaging are flexible for bulk procurement, but exact figures must be verified with the supplier.

Before ordering, importers should verify the grade (TP304/304L or TP316/316L), the exact diameter, schedule and whether the pipe is seamless or welded. Request the mill test certificate and confirm that the dimensions match the ASME tables cited. Any special surface treatments or extra tolerances must be agreed in writing.
Logistics typically involve FOB loading at the nearest Chinese port or CIF delivery to the buyer’s destination. Lead‑time, Incoterms and payment conditions such as L/C or T/T should be confirmed with the supplier, as they are not disclosed in the public listing. Shipping large‑diameter tubes may require custom crating and offshore handling, so discuss container or vessel capacity in advance.
Quality control for these pipes includes visual inspection, dimensional verification and non‑destructive testing if required. Importers are advised to arrange a third‑party inspection at the loading port and to retain all test reports for customs clearance. Confirm that the supplier can provide the required documentation, including certificates of compliance and packing lists.
