Heat Exchanger Ferrules

Heat exchanger Ferrules and Tube Inserts

Tube inserts and Tube ferrules are a metal 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 need for this Tube Ferrule arises as all tube failures occur within the first few inches of the heat exchanger tube inlet-end. The solution to this situation is the use of a thin wall covering in form of metal tube insert expanded full length into the inlet-end of condensers and heat exchangers. FAV tube insert is designed to ensure a smooth and gentle transition of the fluid down the tube insert to the condenser or heat exchanger tube. We have Metal tube insert and Plastic/Delrin Tube Inserts.

 The purpose of the Tube Ferrule Inserts

1)      Protect inlet-end erosion &  corrosion

2)      Act as a protective layer

3)      Reduce the medium impact

4)      Transfer extremely high heat past the tube sheet to the exchanger tubes.

Common problems at Shell & Tube Type Heat Exchangers

1.       Tube-end erosion/corrosion

2.       Stress Corrosion Cracking

3.       Crevice corrosion

4.       Localized pitting

5.       Ammonia grooving

6.       Improper tube expansion

7.       Weakened tube-to-tube sheet joints

For the above problems, FAV tube ferrule inserts offers its most cost-efficient tube protection ,repair, Shield/Seal, also known as a tube insert or ferrule. Although inserts are typically only 3″ – 15″ long, some applications have required lengths up to 3 metres.
