The Slip On Flange Setback Distance Rule node (the SlipOnFlangeSetbackDistance sheet in the Piping Specification.xls workbook) defines the values needed to calculate the distance that the end of the pipe is inserted into the slip-on flange. The software computes this setback distance (shown as A in the figure) as the sum of the fillet weld size and the company practice gap rounded up by the company practice round off factor. The fillet weld size is equal to the pipe wall thickness, limited by the defined maximum weld thickness.

This rule is triggered when the Commodity Type for the flange part is set to FSO - Slip-on Flanges or FRSO - Reducing Slip-on Flanges (select list numbers 55, 500, 66, or 600). Commodity types are defined on the Piping Commodity Type select list or in the PipingCommodityType sheet in the AllCodeLists.xls workbook.

Company Practice Gap (Required)

Enter the distance between the flange face and the edge of the interior weld. This distance, gap, is usually established per a company practice. Include the units of measurement, in or mm for example, when defining this value.

Company Practice Roundoff Factor (Required)

Enter the value to use to round up the sum of the weld thickness and the gap. Include the units of measurement, in or mm for example, when defining this value.

End Standard (Required)

Type the end standard for the bolted end of the slip-on flange. Valid values are defined in the AllCodeLists.xls workbook on the EndStandard sheet in the Codelist Number column.

Maximum Weld Thickness (Required)

Type the maximum weld thickness. Include the units of measurement, in or mm for example, when defining this value.

Nominal Piping Diameter From (Required)

Enter the pipe diameter lower bound for which the company practice gap and roundoff factor apply.

Nominal Piping Diameter To (Required)

Enter the pipe diameter upper bound for which the company practice gap and roundoff factor apply.

Nominal Piping Diameter Units (Required)

Enter the unit of measurement, in or mm for example, for the values in the Nominal Piping Diameter From and Nominal Piping Diameter To columns.
