Tube inserts and ferrules are the same products. A metal, plastic or ceramic tube that is inserted into the end of a heat exchanger tube to provide a specific function. The purpose of a 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 metal tube inserts for all applications, providing the necessary drawings required.
