This option enables you to enter additional pipe and orifice materials as well as modify the existing ones. You can select the ANSI group and enter or modify the linear expansion coefficients. It is possible to define linear expansion coefficients in different ways:
-
One linear expansion coefficient for all temperatures.
-
One linear expansion coefficient with a limitation on the minimum temperature (Tmin) or maximum temperature (Tmax).
-
Two linear expansion coefficients and border temperature. This option allows you to use the first linear expansion coefficient for temperatures lower than the border temperature and the second linear expansion coefficient for temperatures higher than the border temperature.
-
Two linear expansion coefficients, border temperature, and minimum/maximum temperature. This option allows you to use the first linear expansion coefficient for temperatures between minimum and border temperature and the second linear expansion coefficient for temperature between border and maximum temperature.
This option is also available in the Calculation module.
-
In any Process Data module window, on the Edit menu, select Pipe/Orifice Material.
-
In the data window, select fields that you want to edit, and type or select the values from the lists.
-
To enter a new material, select New, and then type or select the value from the respective lists.
-
To delete a material, select the data row and select Delete.
