TEMA Shell & Tube NomenclatureAPI Basco is a proud member of TEMA - Tubular Exchanger Manufacturer’sAssociation. TEMA members set the standards by which virtually all customshell & tube heat exchangers are specified and built. Basco has been a membersince the 1950’s, and consequently we have a complete and comprehensiveunderstanding of the engineering, manufacturing and testing requirements to meetthis world-recognized standard. While other manufacturers may simply interpret theregulations, API Basco has the requisite member design and fabrication capabilitiesto lead the industry by helping to shape and define those standards for the longtermbenefit of all users.
