ceramic tube ferrule inserts
Ceramic Tube insert also called ceramic ferrule which is inserted into the end of a heat exchanger tube to provide a protective function. The purpose of a ceramic tube insert is to either be sacrificial to the effects of inlet-end erosion, corrosion, impingement to induce a fluid to fall on the ID of a tube in a falling film exchanger; or to transfer extremely high heat past the tube sheet to the exchanger tubes.
Each of the above applications requires a specific style of design. At NSI, we manufacture ceramic tube inserts for all applications, providing the necessary drawings required.
The advantage of the ceramic 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.
Types of ceramic tube insert/ferrules we can produce
Straight Tube Ferrule Insert
Bar Stock Ferrule Insert
