Effectively Design Shell-and-Tube Heat Exchangers Thermal design of shell-and-tube heat exchangers (STHEs) is done by sophisticated computer software. However, a good understanding of the underlying principles of exchanger design is needed to use this software effectively. This article explains the basics of exchanger thermal design, covering such topics as: STHE components; classification of STHEs according […]

Guidelines for Correct Tube Expansion The basic purpose of tube expansion systems is to obtain a good hydraulic and mechanical joint. A secondary, but equally important, purpose is to obtain a seal that is durable, resistant to corrosion and essentially free of longitudinal stress. During tube expansion we must take care of ‘over expansion’ and we […]
