Import Astm A312 Tp316 Heat Exchanger Tube — Buy in Bulk from Supplier in China

The ASTM A312 TP316 Heat Exchanger Tube offered by Ark Steel Tube is a seamless stainless steel tube designed for high-temperature and corrosive environments. It conforms to ASTM A312 standards and is manufactured in grade 316, providing superior resistance to chloride pitting and general corrosion. The tube is available with an outer diameter ranging from 3.0 to 608mm and wall thickness from 0.05 to 120mm, with lengths customizable to buyer requirements.

This TP316 variant uses a 300-series austenitic stainless steel alloy, typically composed of 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, which enhances its performance in marine and chemical processing applications. The seamless construction ensures uniformity in wall thickness and strength, while the round shape is standard for heat exchanger and boiler applications. Typical surface finishes for such tubes include pickled, annealed, or polished, depending on the end-use requirements.

Industrial buyers source these tubes for use in heat exchangers, condensers, and pressure vessels in sectors such as petrochemical, pharmaceutical, and food processing. The material’s resistance to sensitization and intergranular corrosion makes it suitable for systems exposed to high temperatures or aggressive fluids. Standard packaging includes bundling with steel strips or wooden cases to prevent damage during transit, and buyers should confirm Incoterms such as FOB, CIF, or CFR for logistics planning.
