ASME Code Only vs TEMA - A Brief Comparison
ASME Section VIII, Division I is a safety Code that was originally developed in the 1930’s and covers all types of pressure vessels, including tanks, columns, towers, reactors, and Shell & Tube Heat Exchangers (HX). It sets minimum requirements with respect to thickness of components and methods of fabrication and testing for the safe operation of a particular piece of relevant equipment.
The TEMA Standard – which stands for the Tubular Exchangers Manufacturers Association – is a specific set of both safe design standards, as well as supplemental requirements and best practices aimed at not only ensuring the safe operation of a Shell & Tube heat exchanger at given conditions, but also that the HX will have a longer life-span than if were fabricated as “Code Only”. In short, when a HX is fabricated in accordance with the TEMA standards, it is a heavier duty product than Code Only.
Given: A 12” Nominal Shell & U-tube Heat Exchanger, designed for 150 PSIG working pressure, to be used in a typical HVAC Steam to Water application.
Shell Thickness- Code Only: 0.190” TEMA Min: 0.375” TEMA is 50% heavier duty
Tube Thickness- Code Only: 0.035” TEMA Min: 0.049” TEMA is 30% heavier duty
Gasket Width – Code Only: Not Addressed TEMA Min: 0.625” to ensure effective seal
# Tie-Rods in Tube Bundle to ensure adequate stiffness – Code Only: Note Addresse , TEMA Min: (4) Tie-Rods
Obviously it is not possible to cover all aspects of the differences between a Code Only heat exchanger, and one designed and fabricated to the TEMA standards in just a few short lines. But when specifying a shell & tube heat exchanger, requiring that it be built to the TEMA standards in addition to ASME Code Only will ensure that the equipment will be fabricated in accordance with the standard that has achieved worldwide acceptance as the authority on the thermal and mechanical design and fabrication of Shell & Tube Heat Exchangers.
When purchasing a heat exchanger, if using heavy duty equipment built to last for years of trouble free service is important to you, ask yourself: Is your heat exchanger Code Only? Or is it TEMA?
