ASME SA283 Gr.C Single Segmental Baffle For Heat Exchanger Application

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. We are professional Baffles Plates For pressure vessel heat exchangers heaters condensers reboilers separators evaporators .

What is the minimum baffle spacing recommended?

Generally between 0.3 to 0.5 off the shell diameter with 50.8 mm (2 inch) being the minimum used

Equation:

0.3 * Shell diameter

to

0.5 * Shell diameter

So if for example we have a shell diameter of 356 mm (14 inch) then the minimum baffle spacing selected should be between 106.8 mm (4.2 inch) to 178 mm (7 inch).

See below for calculations:

0.3 * 356 mm = 106.8 mm (4.2 inch)

To

0.5 * 356 mm = 178 mm (7 inch)

With both values considered valid as they are both above the minimum recommended value of 50.8 mm (2 inch)
