Aspen Shell & Tube Mechanical

Complete mechanical design or rating of shell & tube heat exchangers and basic pressure vessels.

When used in design mode, Aspen Shell & Tube Mechanical optimizes the thicknesses of the majority of exchanger components, including flanges, tubesheets, expansion joints, supports, cylinder thicknesses, and nozzle reinforcement. In rating mode, Aspen Shell & Tube Mechanical determines if the component thickness for an existing exchanger are adequate for a given set of design temperatures and pressures. Aspen Shell & Tube Mechanical is a core element of AspenTech’s aspenONE™ Process Engineering applications.
