Tube insert is inserted into the end of a heat exchanger tube to provide protection to the tube mouth ends of a shell & tube type heat exchanger. The purpose of the tube insert is to either be sacrificial to the effects of inlet-end erosion, corrosion and impingement, or induce a fluid to fall on the ID of a tube in a falling film exchanger, or transfer extremely high heat past the tube sheet to the exchanger tubes.

On specific applications with high temperatures, inconel inserts with ceramic paper wrapping are also used, where the insert`s one end will flared end & the other end will have a reverse taper to hold the ceramic fiber in between.
