Shell & Tube Stainless Steel Heat Exchangers , Carbon Steel Heat Exchangers and High Nickel Alloys Heat Exchangers are the most common type of vessel used in the chemical process industry. As its name implies, this type of vessel consists of a shell filled with a bundle of tubes and sealed at each end by a tubesheet isolating the tubes and the shell.
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, finned.
Shell & Tube Heat Exchangers are used in applications where the demands from high temperatures and pressures are significant. Bendel designs and fabricates all three types of Shell & Tube Heat Exchangers: Fixed Tubesheet, U-tube and Floating Tubesheet.
The Fixed Tubesheet design consists of two stationary tubesheets attached to the shell. The bundle of straight tubes is connected between the tubesheets and contain baffles to direct the flow around the tubes in order to generate the required heat transfer. A channel cover assembly is attached to each tubesheet.
The U-tube design consists of straight length tubes bent into a U-shape with both ends terminating at the tubesheet. The tube bundle is fitted with supports or flow baffles. The tubesheet/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.
A Floating Tubesheet design is similar to the Fixed Tubesheet design except one tubesheet is allowed to move axially within the shell while the other tubesheet is fixed. This configuration allows for the tube bundle to be removable.
