The Tube bundle finished assembling , we will arrange tube side pressure test according to design pressure, and witness by buyer/ TPT/ASME INSPECTOR (A.I.).

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 are baffles in heat exchangers used for?

There are several reasons for using baffles in heat exchangers, below is a list of functions that baffles are often used for.

To support tubes in heat exchangers.

Tubes must be supported at intervals not more than 1.5 m (5 ft), this mainly depends on the diameter of the tube and material of construction. The support intervals can be shorter where flow-induced vibrations occur in certain operations.

Supporting the tubes using baffles also prevents mechanical vibrations that can result in tubes touching each other and giving rise to leakages and failures mainly near tube sheets

To enhance heat transfer by directing the flow through the shell in a desired pattern.

This also increases the turbulence and reduces the stagnant pockets in the heat exchanger. We can also maintain a desired velocity by introducing baffles.
