Demountable fully welded heat exchanger

Structural Features

Fully Welded Structure: The plates are connected by welding, eliminating the need for gaskets and avoiding leakage problems caused by gasket aging in traditional detachable heat exchangers, thus improving equipment reliability and safety.

Removable Design: Despite the fully welded structure, some components (such as end plates) are removable for easy cleaning and maintenance.

Corrugated Plates: The plates employ a herringbone structure, resulting in high heat transfer efficiency and increased fluid turbulence, reducing scaling.

Multiple Material Options: Suitable metal materials can be selected based on different working environments, such as 304, 316L, 254SMo, Hastelloy, titanium plates, and nickel plates.

Compact Structure: Compact structure, small footprint, and high heat exchange efficiency.

Working Principle

Fluid Flow: Hot water from the heat source and heating circulating water enter two independent channels of the heat exchanger.

Heat Exchange: Heat is transferred from the high-temperature hot water to the low-temperature heating circulating water through the plates, achieving heat exchange.

Fluid Discharge: After heat exchange, hot water and heating circulating water flow out from the other end of the heat exchanger, respectively.

Application Scenarios:

Petrochemical Industry: Used for heating and cooling oil products, ethylene cold boxes, and condensation cooling of tower top gases.

Power Industry: Used as steam superheaters, condensers, and heating network heaters.

HVAC: Used in secondary heat exchangers for urban district heating, evaporators for refrigeration and air conditioning, and condensers.

Food Industry: In food processing, copper alloy heat exchangers achieve rapid heat exchange while meeting hygiene and safety standards, ensuring food quality.

Pharmaceutical Industry: Used in heat exchange processes in pharmaceutical manufacturing.

Seawater Desalination: In seawater desalination equipment, stainless steel and titanium alloy heat exchangers successfully resist seawater corrosion, extending equipment lifespan and improving overall economic efficiency.
