Introduction of baffle plate
Baffles are components of shell and tube heat exchangers which are used to support and fix the tubes in a defined position. There are different types of baffle configurations. The most popular type is the perforated plate in the form of a segmented circle. The segmental baffles are arranged so that the segmented section faces are disposed opposite to each other along a bundle of tubes at specified interval. No Tube in Window (NTIW) baffles, Helically-shaped baffles, full support baffle are other types that can be fabricated in our company.
Baffle plate is widely used in shell and tube heat exchanger, boiler, pressure vessel, steam turbine, large central air conditioning,etc. The baffle sheet is mainly used for chemical containers, such as shell and tube heat exchanger, boiler, pressure vessel, condenser, central air conditioning, evaporator, water desalination with the function of supporting the tube bundle and improving heating efficiency.
The material of metal makes it not only has the very strong rigidity, and has a great deal of heat conduction performance.
