Selecting Tube Inserts for Shell-and-Tube Heat Exchangers


A tube insert modifies flow stream characteristics to enhance heat transfer. Here’s how to choose the optimal insert to meet process requirements.

Tube inserts are useful tools that improve tubeside performance in heat exchangers. Inserts are used for applications in which tubeside heat transfer is thermally limiting and an increase in pressure drop is allowed. The best insert type and design for a particular application depends on flow conditions and fluid properties.

This article describes the most common types of inserts and their principles of operation.
