Shell-and-tube heat exchangers use multiple girth flange joints based on their Tubular Exchangers Manufacturers Association (TEMA) type to assemble shell and tube sides.
Shell-and-tube heat exchangers use multiple girth flange joints based on their Tubular Exchangers Manufacturers Association (TEMA) type to assemble shell and tube sides. This permits their disassembly, inspection and cleaning.1 Peripheral gaskets and fasteners play a key role in finalizing the geometry of any flange. Corrosive and environmental cracking services may dictate the requirements for directly exposed bolting materials to specific grades, per international standards, such as NACE MR0175/MR0103.2
This article details a case where the use of special service bolting material grade led to an excessively large external flange joint, resulting in heat exchanger overweight. It also descr
