U Tube Bundles

Overview:-

Tipo U Tube Bundles Shell & Tube Heat Exchangers are the most common type of heat exchanger used in the chemical process industry. As its name implies, this type of heat exchanger consists of a shell filled with a bundle of tubes and sealed at each end by a tube sheet isolating the tubes and the shell.

Features Of U Tube Bundles: –

A fluid or gas flows through the tubes while another fluid or gas flows through the shell causing heat to transfer through the tube walls. The set of tubes is called a tube bundle and may be composed of various tube configurations: plain, longitudinally finned, etc.

Shell & Tube Heat Exchangers are used in applications where the demands from high temperatures and pressures are significant. Fabricates all three types of Shell & Tube Heat Exchangers: Fixed Tube sheet, U-tube and Floating Tube sheet.

Maintenance And U Tube Bundles: –

The U-tube design consists of straight length tubes bent into a U-shape with both ends terminating at the tube sheet. The tube bundle is fitted with supports or flow baffles. The tube sheet/tube bundle is placed in the shell and bolted between the head flange and body flange. A head assembly is required to direct the fluid into and out of the tube bundle. This configuration allows for the entire tube bundle to be removable.

The Fixed Tube sheet design consists of two stationary tube sheets attached to the shell. The bundle of straight tubes is connected between the tube sheets and contains baffles to direct the flow around the tubes in order to generate the required heat transfer. A head assembly is attached to each tube sheet.

U Tube Bundles  for Applications : –

The simple design of a shell and tube heat exchanger makes it an ideal cooling solution for a wide variety of applications. One of the most common applications is the cooling of Hydraulic Fluid and oil in engines, transmissions and hydraulic power packs. With the right choice of materials they can also be used to cool or heat other mediums, such as swimming pool water or charge air. One of the big advantages of using a shell and tube heat exchanger is that they are often easy to service, particularly with models where a floating tube bundle (where the tube plates are not welded to the outer shell) is available. Can also be used on fixed tube sheet heat exchangers.
