Sono stati aggiornati i seguenti moduli del package MT-MECH:
Le modifiche più significative riguardano i moduli MT-COMP/MT-EXCH, per i quali è stata effettuato il controllo completo dei metodi di calcolo per la verifica di congruenza con l'ultima edizione dei Codici (ASME VIII Div. 1 Ed. 2001, TEMA 8.th Ed. 1999). Il programma MT-VESS è attualmente in fase di revisione per assicurare lo stesso livello di congruenza e per includere il codice di calcolo tedesco (AD-MERKBLATT). Prevediamo di rilasciare la nuova versione nei prossimi due mesi.
Per l'elenco completo degli aggiornamenti inclusi nelle nuove releases consultare la tabella seguente che fornisce informazioni di dettaglio per ogni programma.

MT-COMP Revision 2.1.0 (January 2002)
1.The program has been updated to the latest ASME VIII Div.1 2001 Edition.
2.General revision of the tubesheets and expansion joint calculation according to the TEMA 8.th Edition 1999.
3.Calculation of the flange rigidity according to the section S-2 of ASME VIII Div.1 Appendix S.
4.The tables of bolts data for girth flanges calculation have been implemented until 4 inches bolts diameter.
5.Lap Joint flanges have been added to the program.
6.A control has been added to the calculation of flanges according to AD-MERKBLATT to check if the yield strength at the design temperature is equal to zero. In this case a warning message is sent to the user and the yield at room temperature is assumed.
7.The icon on the warning messages at the end of the calculation has been changed.
8.The nozzle program in check has been fixed to allow the reinforcing pad data visualization.
9.The calculation of the floating heads according to ASME and VSR has been revised to avoid convergence missing during the calculation.
10.Some warning messages related to the floating head have been revised to avoid misunderstanding.
11.A control has been added in the MAWP calculation of cones without knuckles and with half-apex angle greater than 30°.
12.The limit to the bolts size of 52 mm has been taken out from the floating head calculation.
13.The possibility of selecting the printer has been added in all the printouts.
14.14. The drivers for the ESL device have been updated.


MT-VESS Revision 1.1.0 (January 2002)
1.The icon on the warning messages at the end of the calculation has been changed.
2.The call to AUTOCAD 2000 has been added to the configuration mask.
3.The crown radius specified in input for elliptical and torispherical heads has been fixed.
4.The tables of bolts data for girth flanges calculation have been implemented until 4 inches bolts diameter.
5.The possibility of selecting the printer has been added in all the printouts provided in the vessel results.
6.The drivers for the ESL device have been updated.


MT-EXCH Revision 2.1.0 (January 2002)
1.The program has been updated to the latest ASME VIII Div.1 2001 Edition.
2.General revision of the tubesheets and expansion joint calculation according to the TEMA 8.th Edition 1999.
3.Calculation of the flange rigidity according to the section S-2 of ASME VIII Div.1 Appendix S.
4.The tables of bolts data for girth flanges calculation have been implemented until 4 inches bolts diameter.
5.The allowable stress for AD-MERKBLATT calculated from the yield values specified in input has been fixed.
6.A control has been added to the calculation of flanges according to AD-MERKBLATT to check if the yield strength at the design temperature is equal to zero. In this case a warning message is sent to the user and the yield at room temperature is assumed.
7.The icon on the warning messages at the end of the calculation has been changed.
8.A bug in the opening of the screen of the nozzles without specifying the TEMA type has been fixed.
9.The printout of the user name in the heading of the calculation results has been fixed.
10.The material of the nozzles T5/T6 appearing in the Bill of Materials for exchangers TEMA types S/T has been corrected.
11.The calculation of the floating heads according to ASME and VSR has been revised to avoid convergence missing during the calculation.
12.The names of the revisions in the exchanger drawing have been blanked when the exchanger is saved with a different name.
13.The call to AUTOCAD 2000 has been added to the configuration mask.
14.The Bill of Materials has been fixed for formed heads with axis nozzle.
15.The knuckle radius specified in input for elliptical and torispherical heads has been fixed.
16.The limit to the bolts size of 52 mm has been taken out from the floating head calculation.
17.Type and size of stiffening rings have been corrected in the exchanger output results.
18.The input data related to calculation conditions of tubesheets have been fixed.
19.The scale factors in the drawing have been implemented to allow the drawing of exchangers longer than 20 m.
20.The possibility of selecting the printer has been added in all the printouts provided in the exchangers results.
21.The corrosion management in the tubesheet has been modified in order to allow the specification of the corrosion both in the shell side and in the tube side.
22.The corrosion management in the floating cover has been modified in order to allow the specification of the corrosion both in the shell side and in the tube side.
23.The drivers for the ESL device have been updated.


MT-LAYOUT Revision 2.1.0 (January 2002)
1.The call to AUTOCAD 2000 has been added to the configuration mask.
2.The possibility of selecting the printer has been added in all the printouts provided in the results.
3.The drivers for the ESL device have been updated.
