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.

Before placing an order, verify the supplier’s ability to meet your exact dimensional and material requirements, particularly for critical applications such as heat exchangers. Request mill test certificates (MTCs) or third-party inspection reports to confirm compliance with ASTM A312 and the specified grade (TP316). Ensure the tubes have been tested for hydrostatic pressure or eddy current inspection if required by your industry standards.
Confirm the logistics details, including the Incoterms (FOB, CIF, or CFR), port of loading, and lead time. For seamless tubes, lead times can vary depending on the outer diameter, wall thickness, and custom length requirements. Discuss packaging options to ensure the tubes are protected against corrosion and physical damage during transit, especially for long sea voyages from China.
For quality assurance, conduct visual inspections for surface defects, dimensional checks using calipers or micrometers, and non-destructive testing (NDT) such as ultrasonic or X-ray for internal flaws. Request documentation such as the material traceability report, heat treatment records, and any applicable certifications (e.g., ISO). If the tubes will be used in regulated industries like pharmaceuticals or food processing, ensure they meet additional hygiene and cleanliness standards.
