Gireesh 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. 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. The U-tube design consists of straight length tubes bent into a U-shape with both ends terminating at the tube sheet.
