Mechanical Design System

MECHX is a dedicated program for the mechanical design of shell and tube heat exchangers and can be used for new equipment or for re-rating existing exchangers for new operating conditions.

The combination of TASC thermal design software and MECHX enables the engineer to rapidly optimize exchanger geometry for both thermal performance and mechanical design constraints during a single session without the need to re-key data. By fully integrating the internationally respected thermal design program, TASC, with a mechanical design program such as MECHX, a cost effective solution is available without compromising quality assurance or mechanical integrity.

MECHX handles all commonly used TEMA shell and tube types using the ASME VII Div. 1 code for the design of exchangers up to pressures of 3000 psi. All of the exchanger components that require a code calculation are displayed on the Calculation List. In a pre-determined order, it performs a calculation for each component, taking account of component interactions. It then provides the user with a ready means of viewing individual results for each component.

The output can either be printed or produced in electronic format for further processing. This output includes:

• Calculation Report- compromising a front sheet, index sheet and selected calculation results as required.
• Tube Layout- a scale drawing of tube layout. All MECHX drawings can be printed or saved as a metafile or .dxf for further processing in a commercial CAD package.
• Setting Plan- a full dimensioned scale drawing of the unit, including the location and standout of process nozzles and supports.
• Baffle Layout- a scaled drawing of the tube bundle, indicating the location of baffles and support plates. It also includes detail views of the baffles indicating the required baffle cut and the location of tierods, sealing strips and bundle runners.
• Bill of Materials- a table detailing all major components: user-defined item number, quantity, component name, material specification and finished geometry. This can be printed out or copied to the clipboard and pasted into other Windows applications such as Excel for further processing.
• Budget Costing- based on individual component and sub-assembly material and labor costs to construct the shell and tube heat exchanger. User defined factors allow costs to be tailored to local conditions and particular manufacturing capabilities. A full report can be printed or saved as a text file for further processing.
• File Export- all mechanical design data can be exported from MECHX as .xml to enable transfer of data into any suitable package for further processing.
