Water Cooled Heat Exchanger Shell Tube

Introduction

A water cooled heat exchanger shell tube water cooled heat exchanger shell tube nge device that transfers heat from a hot fluid to cooling water through tube walls. The hot and cold media remain completely isolated, making it suitable for applications requiring both high-efficiency heat exchange and absolute avoidance of cross-contamination. Our factory's water-cooled shell-and-tube heat exchangers undergo rigorous testing before leaving the factory. These heat exchangers are known for their stable performance, affordable price, and durability. Made with high-quality raw materials, they meet industry standards, ensuring reliable quality and a long service life.

Details

-Product application: oil and natural gas, oil refinery, chemical industry, air compressor, etc.

-Material selection: carbon steel, stainless steel, copper, alloy, titanium, etc.

-Main equipment: rollers, welders, pressure test equipment, etc.

Working Principle
The core principle is "heat conduction" and "convective heat transfer."

1. Hot Side (Shell Side): The high-temperature process fluid flows within the shell side, scouring the outer wall of the heat exchange tube bundle.

2. Cold Side (Tube Side): Cooling water (such as circulating cooling tower water, chilled water, seawater, or river water) flows within the tube side, passing through the inner wall of the heat exchange tubes.

3. Heat Exchange: The heat from the high-temperature fluid is conducted to the cooling water through the tube wall (usually a highly thermally conductive metal, such as copper, stainless steel, or titanium), raising its temperature.

4. Medium Separation: Throughout the entire process, the fluids on both sides are completely separated and do not mix; only heat is exchanged.

Technical Parameters

1. Material: Stainless steel, carbon steel, alloy materials, etc.

2. Heat Exchange Area: Varies from a few square meters to hundreds of square meters depending on the model.

3. Working Pressure: Can be designed for high or low pressure, depending on application requirements.

4. Working Temperature: Generally can withstand -20℃ to 250℃; special cases can be customized.

Feature

1. High Reliability and Durability: Mature design, robust structure, and long service life (up to 20 years or more).

2. Powerful Processing Capacity: A single unit can handle extremely high heat loads (from several kilowatts to tens of megawatts), suitable for large-scale industrial processes.

3. High Pressure Resistance: Both the shell and tube sides can be designed to withstand high pressures (especially the tube side, up to tens of MPa).

4. Wide Adaptability: Adaptable to harsh environments such as corrosive media and seawater cooling by selecting different materials (carbon steel, 304/316 stainless steel, titanium, copper-nickel alloys, etc.).

5. Relatively Convenient Maintenance and Cleaning: For removable tube sheet designs, tube-side (water side) cleaning is convenient. For fixed tube sheet designs, chemical cleaning can be performed on the shell side.

6. Mature Technology and Comprehensive Selection Software: Comprehensive design and manufacturing standards (such as ASME, TEMA, GB151) ensure accurate selection calculations.

Maintenance and Care

1. Regular Inspection: Regularly check for leaks and corrosion to ensure normal equipment operation.

2. Cleaning and Maintenance: Clean regularly according to usage to prevent scale buildup that could affect heat exchange efficiency.

3. Parts Replacement: Replace any damaged or aged parts promptly to ensure equipment safety and reliability.

Selection and Maintenance Considerations:

1. Calculate the required heat exchange area based on flow rate, temperature drop, allowable pressure drop, and fouling factor.

2. When the cooling water hardness is high, scaling is prone to occur in the tubes; a detachable design with pre-existing cleaning space should be selected.

3. For seawater or high-chlorine environments, titanium tubes or Cu-Ni 90/10 alloy tubes are preferred to prevent pitting corrosion.

4. Equipping with a temperature control valve and bypass can prevent excessive cooling leading to low condensing pressure or low oil temperature.
