Pressure Vessel Heat Exchanger

A pressure vessel heat exchanger is a device used for heat exchange under pressure, widely used in chemical, petroleum, power, pharmaceutical, and other industries. It achieves process requirements such as heating, cooling, or phase change by transferring heat from one medium to another. Here are some key points about pressure vessel heat exchangers:

1. Type
Shell and tube heat exchanger: The common type, consisting of a shell and a tube bundle, one fluid flows in the tube and the other fluid flows on the shell side.
Plate heat exchanger: It consists of a series of corrugated plates, and the fluid flows between the plates, with high heat transfer efficiency, but low pressure bearing capacity.
Spiral plate heat exchanger: It is composed of spiral plates and is suitable for media with high viscosity or containing solid particles.
Air cooler: It uses air as a cooling medium and is suitable for water-deficient or high-temperature environments.
U-tube heat exchanger: The tube bundle is U-shaped and is suitable for occasions with large temperature differences.

2. Design points
Pressure level: Select the appropriate design standard (such as ASME, GB, etc.) according to the working pressure.
Material selection: Select appropriate materials according to the characteristics of the medium (corrosiveness, temperature, etc.), such as carbon steel, stainless steel, titanium alloy, etc.
Thermodynamic calculation: including the calculation of parameters such as heat transfer coefficient, pressure drop, and heat load.
Structural design: including the design of shell, tube sheet, tube bundle, support structure, etc., to ensure the strength and sealing of the equipment under high pressure.

3. Manufacturing and inspection
Manufacturing standards: follow international or national standards such as ASME, PED, GB150, etc.
Welding process: welding is a key link in manufacturing and non-destructive testing (such as radiographic testing, and ultrasonic testing) is required.
Pressure test: including water pressure test and airtightness test to ensure the safety of the equipment.

4. Application areas
Petrochemical: used for crude oil heating, reactor cooling, etc.
Power industry: used for boiler feed water heating, steam condensation, etc.
Pharmaceutical industry: used for heating or cooling processes in drug production.
Food industry: used for sterilization and cooling in food processing, etc.

5. Maintenance and troubleshooting
Regular cleaning: prevent scaling and clogging, which affect heat transfer efficiency.
Check sealing: prevent leakage and ensure safe operation of equipment.
Corrosion protection: regularly check corrosion and replace damaged parts in time.

6. Safety precautions
Pressure monitoring: ensure that the equipment operates at rated pressure to avoid overpressure.
Temperature control: prevent overheating or overcooling from causing material failure.
Emergency shutdown: shut down in time under abnormal conditions to avoid accidents.
