Floating Crude Oil Heat Exchanger

The crude oil heat exchanger is comprised of a shell housing a bundle of tubes. One fluid circulates through the tubes, while another fluid flows through the shell, facilitating heat transfer between the two fluids. Floating head heat exchangers find widespread application in high-temperature environments between the shell and tube bundle, as well as in dirty service industries such as petroleum refineries.

Product Description

Floating crude oil heat exchanger is one end of the tubesheet is fixed to the shell, while the other one can “float” freely inside the shell. Floating head heat exchanger is widely used for the service where the temperature is high between the shell and tube bundle, or the dirty service, like the petroleum refinery.
