A shell and tube type heat exchanger consists of a shell, tube bundle, tube sheet, baffle, tie rod, and two heads or caps at both ends of the shell. By selecting different design of these basic parts, we can have different types of heat exchanger as per TEMA. Shell and Tube type heat exchangers are further classified on the basis of their design.

Repairing, replacement, retubing, testing, & reconditioning services for products & parts including shell replacement, channels, channel covers, tubes, tubesheets, baffles, tie-rods & spacers, seal strips are also available.
Apr 23, 2019 · Tie Rods Baffles are supported by tie rods. Tie rods are made from solid metal bar. Normally four or more tie rods are required to support the baffles. Diameter of tie rod is less than the diameter of tube. Diameter and number of tie rods required for given shell diameter are specified by TEMA standard and IS:4503. 11.
Petroleum Community Forum - Shell-and-Tube Heat They hold the baffle assembly together. The spacers are placed over the tie rods between each baffle to maintain the selected baffle pitch. The minimum number of tie rod and spacers depends on the diameter of the shell and the size of the tie rod and spacers. Channels (Heads) Channels or heads are required for shell-and-tube heat exchangers to
Shell and Tube Heat Exchangers Construction DetailsThe tubes are thin-walled tubing produced specifically for use in heat exchangers. Other components include:the channels (heads), tubesheets, baffles, tie rods & spacers, pass partition plates and expansion joint (when required). Shell & tube heat exchanger designs and constructions are governed by the TEMA and ASME codes.
1 Rod size. The tie rod connection dimensions are as shown in the figure and Table 4. Table 4 Tie rod size. 2 Rod arrangement. Pull rods should be arranged as evenly as possible on the outer edge of the tube bundle. For large diameter heat exchangers, a suitable number of tie rods should be placed in or near the baffle notch. Double shell structure
