ASME SA213 TP347H Chemical Composition

Heat Exchanger Tube Application

1. Petrochemical industry

• Oil refinery: Heat exchangers, condensers and reboilers for atmospheric and vacuum units, catalytic cracking units, hydrofining units, etc.
• Chemical plant: Heat exchangers, condensers and reactors for the production of ethylene, propylene, styrene and other chemical products.
• LNG plant: Heat exchanger and cold box for LNG plant.

2. Electricity

• Thermal power plants: superheaters, reheaters and economizers for boilers.
• Nuclear power plant: For steam generators, condensers and feedwater heaters.

3. Other

• Solar energy: heat exchange tubes for solar collectors.
• Geothermal energy: heat exchange tubes for geothermal heat exchangers.

Heat Exchanger Tube Strength

1. Excellent high temperature resistance

• High temperature strength: Adding niobium element to enhance the high temperature strength, suitable for high temperature environment.
• Oxidation resistance: It has good oxidation resistance at high temperatures and prolongs service life.

2. Excellent corrosion resistance

• Intergranular corrosion resistance: Niobium effectively prevents intergranular corrosion and is suitable for corrosive media.
• Stress corrosion resistance: Good stress corrosion resistance in chloride-containing environments.

3. Good creep resistance

• Creep resistance: Excellent creep resistance at high temperature and pressure to ensure long-term stable operation.

4. Easy to process and weld

• Machinability: It has good plasticity and toughness, easy to process and form.
• Weldability: Good welding performance, can use a variety of welding methods.
