The following MT-MECH modules have been revised:
The major improuvements concern the MT-EXCH program where a complete new national code (AD-MERBLATT - Germany) has been included making available the only software product for Heat Exchanger Mechanical Design with 3 National Codes included by default.
For a complete list of the new releases contents see the tables herebelow each one specific for a program.

MT-COMP Revision 8.0.3 (September 2001)
1. A control has been added to the MAWP calculation of flat flanged head. The MAWP is not calculated when the controlling thickness does not depend on pressure.
2. The length of the path for the file name of shells and heads has been updated at 256 characters. It was set before at 65 characters and the calculation went in error for path longer than 65 characters.
3. The neck length calculation of expansion joint has been fixed.
4. The MAWP calculation for hydraulic test pressure on the floating head component has been fixed.
5. The management of the external pressure has been modified to allow both negative and positive input values on all the components.
6. The material name of the tubesheet printed on the calculation datasheet has been fixed.
7. The code "No reinforcement" has been added to the type of reinforcement of nozzles. When no reinforcement is selected the program calculates the pipe thickness only and no compensation analysis is done.
8. The contribution of the pass partition ribs has been added to the floating flange. The method of calculation is taken from TEMA RGP-RCB-11.7
9. Operating temperatures on the fixed tubesheets are now assumed as the corresponding design temperatures if the user does not specify them.
10.Some bugs on the material changes have been fixed.
11. A flag showing that the material data have been changed has been added to the program.


MT-EXCH Revision 7.0.7(September 2001)
1.The code AD-MERKBLATT (German code) has been added to the program allowing to use this code for one-step calculation of the whole exchanger.
2.The Bill of Materials capability has been added to the program.
The Bill of Materials can be viewed, printed or exported as CSV (Comma Separated Values) or EXCEL files for further processing.
3.The Audit Report Book has been added to the program.
The datasheets with formulas for all the components of the exchangers are automatically produced from inside MT-EXCH and can be viewed, printed or saved as file.
4.The formula evaluation has been added to all fields of the numerical input data.
The following operators are provided:
+ summation
- subtraction
* multiplication
/ division
^ power exponent
Parentesis can be used to group the data.
The formula is evaluated by pressing enter in the field.
5.The transversal forces generated by wind and earthquake over support saddles have been divided by two to correctely distribute the force over each saddle.
6.The types of junction of tubes to tubesheet has been implemented to comply with the tables specified in the codes.
