Removable Bundle and Externally Sealed Floating Tube sheet: Type AEW, BEW

No ability to absorb thermal expansion between the outer shell and tube bundle.

Shell side can only be cleaned by a chemical solution.

Less costly than removable bundle designs.

The tube sheet is welded to the shell and heads are bolts to the tube sheet. This design is the simplest design and most economical in most cases. Straight Tube and Fixed Tube Sheet: Types BEM, AEM, NEN, etc The figure below is helpful in visualizing each segment. IE: TEMA Type BEM would have the “B” representing the front head, the “E” the core or middle section and M representing the rear head designs. TEMA designations refer to portions of the unit that make up the complete heat exchanger. TEMA B and TEMA R are similar in requirements and typically require features like, confined gaskets joints, spiral wound gaskets along with some greater minimum thicknesses on some parts. TEMA C is the least restrictive and most widely used. There are 3 major TEMA classifications, which are as follows

One of the advantages of selecting a shell & tube manufacturer that builds to TEMA specifications is that the end-user is assured that they will receive and install a piece of equipment that is built to certain specification’s and criteria. These standards define the style of heat exchanger and the machining and assembly tolerances. Reach us at 71.TEMA stands for “Tubular Exchangers Manufacturers Association” and is a set of standards that were developed by leading shell and tube manufacturers.
