The product is a seamless pipe made from TP304 stainless steel (UNS S30400) and conforms to ASTM A312 as well as GB/T 14976‑2012 and related standards. Outer diameter ranges from 6 mm to 762 mm, with wall thickness between 0.9 mm and 50 mm and schedules such as SCH 5, SCH 10, SCH 40, SCH 80 and SCH 160. Lengths are offered in fixed 6 m sections or to customer‑specified random lengths, and delivery time is quoted as 30‑45 days after order confirmation.
The pipe’s alloy provides strong resistance to corrosion and retains mechanical strength at elevated temperatures, making it suitable for high‑pressure service. Typical surface conditions include bright annealed, pickled, cold‑drawn and polished finishes ranging from 180 g to 800 g mirror shine. Standard nondestructive testing methods such as ultrasonic (UT), radiographic (RT) and magnetic particle (MT) are applied, and the material carries an ISO 9001‑2008 quality system certificate.
Major end‑users are EPC contractors and plant engineers in oil‑and‑gas, petrochemical, power generation, water‑treatment and shipbuilding projects. The supplier lists payment terms of T/T or L/C and ships the product in wooden crates, plastic bags or custom‑packed containers. Because the listing does not disclose minimum order quantity or exact freight terms, buyers should confirm those details directly with the supplier before finalising a contract.

Before placing an order, verify that the material certificate matches the TP304 grade and that the supplier can provide the relevant EN 10204 3.1 test reports, chemical composition analysis and mechanical property data. Request a recent third‑party inspection report (e.g., SGS or BV) to confirm conformity with ASTM A312 and any additional client‑specific standards. Confirm that the packaging meets your handling requirements and that the crate dimensions fit the intended container type.
Logistics for this product are typically arranged on an FOB basis from ports in Zhejiang Province, but the exact incoterm should be agreed in the sales contract. Buyers should ask the supplier to confirm the estimated lead time, which is quoted as 30‑45 days, and to provide a draft shipping schedule that includes vessel ETA and inland transport options. Payment milestones, such as a 30 % deposit and balance against documents, are common and can be tailored to risk preferences.
Upon receipt, conduct a visual inspection for surface defects, verify the dimensions against the order sheet, and request a final mill test report. If possible, arrange a third‑party hydrostatic test at the destination port to ensure pressure integrity. Retain all certificates, test reports and packing lists as part of the import documentation for customs clearance and future quality audits.
