ASME SA213 TP316 (UNS S31600) Stainless Seamless Tube for Heat Exchanger and Boiler

ASME SA213 TP316 (UNS S31600) is a seamless austenitic stainless steel tube specifically designed for high-temperature service in heat exchangers, boilers, and superheaters. It offers excellent corrosion resistance, high-temperature strength, and oxidation resistance due to its molybdenum-enhanced composition. This material complies with the ASME Boiler and Pressure Vessel Code, ensuring reliability in critical thermal applications.

1.Chemical & Mechanical Properties

Mechanical Properties

2. Key Adventages

• Superior Corrosion Resistance

Molybdenum-enhanced (2%~3% Mo) resists pitting and crevice corrosion in chloride environments.

High chromium-nickel content resists acids, alkalis, and oxidation in harsh conditions (e.g., chemical, marine).

• High-Temperature & Pressure Performance

Maintains strength at high temperatures with excellent oxidation/creep resistance for boilers & heat exchangers.

The maximum temperature resistance can reach 1040℃ (1900℉).

• Excellent Fabrication & Weldability

Seamless cold/hot forming allows bending/flaring without cracking.

Compatible with TIG/MIG welding, no post-weld heat treatment required.

• Long Service Life & Low Maintenance

Smooth seamless interior minimizes scaling, reducing maintenance costs.

Long-term cost efficiency due to extended service life.

3. Key Applications

• Power Generation Industry

Power station boiler systems: Superheaters, reheaters, and main steam pipes for supercritical/ultra-supercritical boilers.

Nuclear power equipment: Auxiliary cooling systems and steam generator heat transfer tubes.

• Petrochemical Industry

Refining units: Pipes for high-temperature/pressure reactors (e.g., catalytic cracking, hydrocracking).

Chemical heat exchangers: Shell-and-tube/plate heat exchanger cores resistant to acids, alkalis, and salts.

• Marine & Shipbuilding

Desalination systems: Chloride-resistant pipes for MSF and RO plants.

Marine propulsion systems: Exhaust pipes for gas turbines, fuel boiler tubes.

• Environmental & New Energy

Waste-to-energy plants: Flue gas heat recovery pipes with high-temperature corrosion resistance.

Hydrogen energy equipment: Hydrogen-resistant pipes for electrolyzers.
