The Liquid steel tube offered by Tianjin Sanjuyuan Trade Co., Ltd is a heavy‑walled seamless pipe intended for the conveyance of molten steel and other high‑temperature fluids. It is manufactured from carbon steel or low‑alloy steel to the P22 grade, which is equivalent to the ASTM A335 specification. The tube is supplied in a range of diameters and wall thicknesses to suit different plant requirements.
In the steel‑pipe industry, heavy‑walled seamless tubes are commonly produced in outer diameters from 50 mm up to 200 mm with wall thicknesses between 8 mm and 25 mm, tolerances typically ±0.2 mm. Standard dimensions follow the ASTM A335 and API 5L guidelines, and many users apply an anti‑corrosion coating to extend service life. Typical lengths are six metres, and the tubes are delivered in bundled packs for efficient handling. These typical parameters align with the needs of foundries and continuous‑casting facilities.
Primary users include steel mills, foundries and heavy‑industry plants that require reliable transport of molten metal. The supplier states flexible minimum order quantities and offers both FOB and CIF shipping terms, allowing buyers to choose the most suitable logistics arrangement. Buyers should request confirmation of any required certifications such as ISO 9001 or SGS inspection reports. Payment terms and detailed lead times are negotiated directly with the supplier before contract finalisation.

Before placing an order, verify that the tube material matches the P22 grade and that the supplier can provide the relevant ASTM A335 test certificates. Request a mill test report and, if a coating is required, ask for coating thickness and adhesion test results to ensure durability in high‑temperature service.
Logistics for heavy‑walled steel tubes usually involve container loading at a Chinese port followed by ocean freight. Confirm whether the supplier will ship under FOB or CIF terms, specify the destination port, and ask for an estimated lead‑time based on your order size. Payment conditions such as a letter of credit or advance payment should be agreed in writing before production commences.
Upon arrival, arrange for a third‑party inspection to check dimensions, wall thickness tolerance and coating integrity. Insist on receiving the mill test report, certification copies and a packing list that details bundle counts. Proper documentation will streamline customs clearance and ensure the product meets your project specifications.
