Advantages of this type include the removable bundle, externally sealed floating tubesheet design. Shell and tube heat exchangrs can be divided into three major parts, these parts are the front head, shell section, and rear head. This TEMA type is the simplest design and is constructed without packed or gasketed joints on the shell side. TEMA is a set of standards that defines the heat exchanger style and machining and assembly tolerances to be employed in the manufacture of a given exchanger. – The flanged channel end costly and prone to leakage – Used for low tubeside pressure and fouling tubeside fluid Also, there is less surface per given shell-and-tube diamater than other removable designs. Vendors who build to TEMA standards can be competitively compared because tolerances and construction methods should be very similar for a given design. – Can be use with fixed or removable tube bundles Also, it provides a multipass tube circuit arrangement.

We may have two fluids in the shell and tube exchanger on both - shell side and tube side. Defining the major TEMA constructions and identifying their advantages, limitations and applications suitable for each type can be advantageous to your process.

It is well suited for applications requiring frequent tube-bundle removal for inspection and cleaning. This article only discuss the designations provided in TEMA standards. Each of these components is available in a number of standard designs. TEMA Heat Exchanger Designations | TEMA Rear head types. U Among the most common types of heat transfer equipment used in industrial applications are the various configurations of shell-and-tube heat exchangers. We also have a broad network of specialized partners worldwide. Types in this category include AET and BET, which are suitable for applications that require frequent tube bundle removal for inspection and cleaning as the floating head is bolted directly to the floating tubesheet. This part provides a short summary onf the TEMA rear head types. Or do you want more information? This design has several advantages. – If frequent mechanical cleaning of tube side is needed then this type isn’t recommended.

In 304 stainless steel. A Heat exchangers of this design may be interchangeable with other manufacturers of the same TEMA type. This design has several advantages. Straight-Tube, Fixed Tubesheet Type Heat Exchangers. – Used for high tube side pressure and relatively less fouling tube side fluid. This design also has limitations.
