Since 2009 tanks for the transport of dangerous goods have to be calculated per EN 14025 !
Flat or dished covers for manholes can be calculated with module DECK according to EN 14025. The program calculates the required cover thickness and the required bolt area. A flat or dished design type can be selected at program start and an appropriate input window follows with the required input values for the calculation. The input window is dynamically adapted according to the specifications and displays only the required input data and equations. For example, the required cover thickness for a full face gasket is independent from the bolt force. For a narrow face gasket additional input data and equations for the static forces are displayed.
Some parameters are automatically inserted by the program. For example, a gasket type according table 3 in EN 14025 can be selected and the program determines the required gasket parameters. The bolt di-mensions for metric DIN-bolts are also automatically evaluated.
1. Circular or elliptical flat endsFor man holes with flat covers circular or elliptical and narrow face or full face gaskets can be selected. The most important input values are illustrated in Fig. 8 and Fig.9.

 Fig. 8 - Circular or elliptical flat ends with narrow face gasket |
 Fig. 9 - Circular or elliptical flat ends with full face gasket (Only for liquid media) |
2. Dished headsFor dished heads narrow or full face gaskets can be selected. For narrow face gaskets the offset hr bet-ween shell center and flange center at the welding 1 in Fig. 11 must be specified. Price: 1200 EUR plus VAT
