Tubular Exchanger Manufacturers Association

[2] TEMA also produces software for evaluation of flow-induced vibration and of flexible shell elements (expansion joints).

[3] The association meets regularly to revise and update the standards, respond to inquiries, and discuss topics related to the industry.

[9][10][11] Each class has different mechanical construction requirements, based on the expected service.

For example, a fixed tubesheet exchanger with bolted removable bonnets is designated as a 'BEM' type.

The member companies of TEMA must demonstrate high quality exchanger fabrication standards, and possess in-house engineering capability for mechanical and thermal design of shell and tube type heat exchangers.
