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.
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
