EN 10025-2 S235JR Baffle Plate for Heat Exchanger Structural Support and Heat Transfer Efficiency

EN 10025-2 S235JR Baffle Plate Used In Heat Exchanger

EN 10025-2 S235JR is a standard for hot-rolled structural steel that specifies the technical delivery conditions for non-alloy structural steels. It is commonly used in construction, machinery manufacturing, and other structural applications.

A baffle plate is a component used in heat exchangers to enhance heat transfer efficiency. It is typically made of a material that has good thermal conductivity, such as stainless steel or carbon steel. The baffle plate is designed to direct the flow of fluids inside the heat exchanger, creating turbulence and increasing the surface area available for heat exchange.

In the context of heat exchangers, the use of EN 10025-2 S235JR steel for baffle plates would provide structural strength and durability while maintaining good thermal conductivity. The specific design and dimensions of the baffle plate would depend on the requirements of the heat exchanger and the desired heat transfer performance.

Why are baffles provided in heat exchangers?

Baffles are used in shell and tube heat exchangers,

• To provide structural support to inner tubes.
• To reduce the mechanical vibration of tubes. This also reduces leakages and failures near tube sheets.
• To direct the shell side fluid in the desired direction over the tubes. This creates turbulence on the shell side.
• To increase heat transfer rate: Due to increased turbulence on the shell side, the convective heat transfer coefficient increases. This results in increased effectiveness of the heat exchanger.
