Frequently Asked Questions About Liquid steel tube from Tianjin Sanjuyuan Trade Co., Ltd
The tube is made from carbon steel or low‑alloy steel to the P22 grade, which matches the ASTM A335 specification as stated by the supplier.

Sourcing Liquid steel tube from Tianjin Sanjuyuan Trade Co., Ltd - China Import Guide

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.
