H&C Heat Transfer Solutions

We would like to thank H&C Heat Transfer Solutions for helping with this heat exchanger design. PVEng does not provide heat transfer calculations for heat exchanger designs. We have been working with Kam Hau, P. Eng. at H&C for several years and are very impressed with the expert help and deep knowledge provided. www.hcheattransfer.com


This exchanger has been designed in accordance with Part UHX of ASME Section VIII Division I. ASME requires analysis of seven separate load cases on fixed tubesheet exchangers. The cases are made up using all combinations of tube side and shell side design pressures and loadings due to thermal expansion.

ASME UHX design is mandatory and replaces the previously used TEMA rules. As can be seen from the calculation set linked below, the UHX calculations are much more complicated and require more information from the designer. Changes in required tubesheet thickness (often thicker vs TEMA) have been noted by designers.

PV Elite

The ASME code calculations with the UHX tubesheet calculations were run in Intergraph PV Elite software PV Elite. We prefer to use PV Elite to design heat exchangers. The PV Elite Report is attached below.

SolidWorks Drawing

The drawing is created in SolidWorks. By preference, we use SolidWorks to create heat exchanger drawings unless a very good reason for using AutoCAD is provided. The drawing provides all required information to order material and fabricate without referring to the calculation set – a standard in pressure vessel drawings. Solid modelling is a very useful tool in the design of heat exchangers where many components must fit accurately.
