Vikoll,

The allowable stress information for 149 deg C would be valid, and there would not be MONDI applications above that temperature.

The supplier of MONDI has weight-dimension information. Any information should be confirmed with your supplier. Design dimensions probably need to be used for creating CAD database, as well as for stress analysis. Catalog data of manufacturers like ACIPCO, Clow, Tyler, and USPipe could provide additional data and design guidance.

There is previous thread 'ductile iron piping stress analysis' from Aug02 2005 that could be located by search of the forum.
