About Wall Thickness Values for DIN Parts

You can generate wall thickness values for DIN parts based on selected part properties.

To generate correct wall thickness values, you can use an editable mapping table to match selected part property values from a piping spec to a mapping table. Unlike ANSI parts, DIN parts obtain wall thickness values from various combinations of parts properties. You use the mapping table to match up the values of specific properties of DIN parts with the same values of the coordinating properties in the wall thickness mapping table.

In some cases, depending on the properties criteria you select for a part, no wall thickness value may exist. In other cases, multiple wall thickness values may exist. You can assign a value to a part from the mapping table if there are no values returned. When there are several properties matches returned, you can select the most appropriate value to use.

Following are parts properties you can select individually or in combination to generate wall thickness values:

• Nominal Diameter
• Pressure Class
• Material Code
• Design Pressure Factor
• Design Standard
• Schedule
• Industry Standard

The Nominal Size property is a required match to serve as a basis for wall thickness mapping. You can select the remaining properties as required or optional matches.

Following is the workflow for assigning wall thickness values to DIN parts:

• Select required properties for DIN parts to match in the mapping table to generate wall thickness values.
• Assign specific wall thickness values to parts based on mapping table results.
• Edit mapping table values when necessary.

You can add DIN and ANSI parts to the same spec sheet and generate wall thickness values only for parts in a spec derived from the DIN catalog.
