TEMA DESIGNATIONS BEM: Bonnet (Integral Cover), One Pass Shell, Fixed Tube sheet Bonnet Fixed tube sheet heat exchanger. Is a version with one shell pass and two tube passes and a very popular version as the heads can be removed to clean the inside of the tubes. The front head piping must be unbolted to […]

TYPES OF SHELL CONSTRUCTIONS TEMA-E: This shell is the most common shell type, as it is most suitable for most industrial process cooling applications. TEMA-F: This shell design provides for a longitudinal flow plate to be installed inside the tube bundle assembly. This plate causes the shell fluid to travel down one half of the […]

In intercoolers, boilers, pre-heaters and condensers inside power plants as well as other engineering processes, heat exchangers are utilized for controlling heat energy. Heat exchangers are devices that regulate efficient heat transfer from one fluid to another. There are two main types of heat exchangers. The first type of a heat exchanger is...

Shell and Tube Heat Exchangers Tube size: Length is standard, commonly 8, 12 or 16 ft. Diameter: most common 3/4 or 1 in OD Tube pitch and clearance: Pitch is the shortest center-to-center distance between adjacent tubes. Commonly 1.25 to 1.5 times the tube diameter. Clearance is the distance between tubes. It should be larger […]
