Description

The Eleventh Edition of the TEMA Standards was prepared by the Technical Committee of the Tubular ExchangerManufacturers Association. Sections have been added to provide direction concerning the design of one passfloating heads and Type-D high pressure channel closures. The Eleventh Edition introduces an Exchanger TypeSelection Guide which discusses the benefits and disadvantages of various types of exchangers and a section onInspection which has information concerning non-destructive examination techniques and recommendations fortheir use for shell and tube heat exchangers. This edition includes new appendices for Repairs and Alterations ofHeat Exchangers; for Clad and Overlay Construction; and for Installation, Operation, and Maintenance of Shell andTube Heat Exchangers. TEMA has modified the Heat Exchanger Specification Sheet to better define the designrequirements necessary to specify a heat exchanger. This Standard has been revised to include weld calculationsfor vertical support lugs, a clarification to the mitigation of erosion of the tube ends due to certain tube side flows, and a more detailed discussion concerning tube to tubesheet joints.
