ASTM A213 TP316L Stainless Steel U TUBE For Boiler and Heat Exchanger

This product is a high-performance U-Tube specifically designed for boilers, superheaters, heat exchangers, and condensers operating under high-pressure, high-temperature, and corrosive environments. Manufactured from ASTM A213 TP316L, a low-carbon austenitic stainless steel, it offers superior corrosion resistance, high-temperature strength, and excellent formability and weldability, making it a critical component for thermal efficiency and long-term equipment reliability.

1.Chemical & Mechanical Properties

Mechanical Properties

Available Size Range

Outer Diameter (OD): Common range from 9.53mm (3/8") to 25.4mm (1"), other sizes available upon request.

Wall Thickness (WT): Common range from 0.8mm to 2.5mm (corresponding to different ODs).

U-Bend Radius (R): Customized according to customer design and tube bundle layout.

Straight Leg Length: Precisely cut as per customer drawings.

2. Key Advantages

• Superior Corrosion Resistance

The addition of Molybdenum (Mo) in TP316L provides enhanced resistance to pitting and crevice corrosion compared to 304 series, making it ideal for chloride-containing environments.

• Ultra-Low Carbon Content

The "L" grade denotes a maximum carbon content of 0.030%, which minimizes the risk of carbide precipitation during welding and exposure to the sensitization temperature range (425-860°C), thus preventing intergranular corrosion.

• Excellent High-Temperature Properties

Maintains good mechanical strength and creep resistance at elevated temperatures, ensuring structural integrity under prolonged service.

• Precision U-Bending Process

Advanced bending techniques ensure uniform wall thickness, no wrinkling, or excessive thinning at the U-bend. The smooth inner surface minimizes pressure drop and maintains consistent heat transfer efficiency.

3. Key Applications

Heat Exchanger (Shell-side less corrosive) —— To handle thermal expansion

Condenser / Seawater Cooler —— Resist chloride ion corrosion

Boiler / Superheater —— High-temperature strength & oxidation resistance

Petrochemical and Chemical Processing —— Resist intergranular corrosion after welding
