Vibration of tubes in heat exchangers is an important limiting factor in heat exchanger operation. The vibration is caused by nonstationary fluid dynamic processes occurring in the flow.

These are turbulent pressure pulsations (see Turbulent flow), vortex initiation and separation from tubes in crossflow (see Crossflow), hydroelastic   T.

Pulsation and/or vibration can cause metal fatigue and lead to failure of the heat exchanger. If the heat exchanger is used in a pneumatic conveying system, a check valve should be placed between the air lock and the heat exchanger.

This will help to prevent clogging the heat exchanger with the product being conveyed.

The shell and tube exchanger basically consists of a number of connected components, some of which are also used in the construction of other types of exchangers.

The pressurized components of the shell and tube exchanger are designed to be in accordance with a pressure vessel design code such as ASME VIII () or BS ()  tional features of a shell and tube heat exchangers and its relative dimensions.

The Rating module allows the user to calculate whether a selected exchanger can meet the required thermal and hydraulic duty. User inputs of geome-trical dimensions of the heat exchanger to be rated is required.
