U Tube Thickness Design Spreadsheet Calculations

Be the First to Review

In a shell and tube heat exchanger two fluids circulate in a different temperature conditions exchange heat through the walls of the tubes without direct contact between the fluids. The fluid flowing inside the heat transfer tubes that belongs to the tube bundle they finds the tube side of a shell and tube heat exchanger. On the contrary the fluid flowing inside the shell of the exchanger defines shell side of a shell and tube
heat exchanger.

Most domestic water to water or steam to water heat exchangers are constructed of steel tube sheets with copper tubes. Most tubes are rolled into the tube sheet to assure proper tube seating. Then copper or steel intermediate tube sheets are used based on length of bundle to make sure that tubes remain straight and are supported along the entire length of the bundle. Most tube sheets tie into the shell with a “between the bolt” type arrangement with gaskets on head and shell sides of tube sheet.
When the plot size of the heat exchanger in the installation is critical, Geurts can design and build a u-tube type heat exchanger where the tube bundle fits inside a rectangular casing. This applies to low pressure operations only, for instance gas-gas or gas-liquid applications. Ducts are more easily connected and a finned tube design offers extra size reduction.

Also, if round tubes do not comply, we offer the option for rectangular tubes. In any case, the size of your custom-engineered exchanger is substantially smaller without compromising the capacity.

Example industries for u-tube heat exchangers are:

*Industrial waste heat recovery solutions
*Oil and gas industry
*Chemical industry
