The Field Fit Length node (the FieldFitLength sheet in the Piping Specification.xls workbook) defines the extra length of pipe to add for field fit welding. This rule only applies to field fit welds and not to shop welds or field welds. If, for a field fit weld, no matching criteria is defined in this rule, the software reports an error and the field fit welded connection is not created. The extra length is not shown graphically in the model but will cause an increase in the reported pipe lengths.

Although Weld Type is used to select which field fit length is used from this rule, the field fit length is only applied to the pipe cut length calculation when the Weld Class is set to "By Pipe Erector, Field Fit" or "By Pipe Erector for Loose Material."

Construction Requirements End 1 (Required)

Type the construction requirement codelist value for end 1. Valid codelist values are defined in the AllCodeLists.xls workbook on the ConstructionType sheet in the Codelist Number column.

Construction Requirements End 2 (Required)

Type the construction requirement codelist value for end 2. Valid codelist values are defined in the AllCodeLists.xls workbook on the ConstructionType sheet in the Codelist Number column.

Field Fit Length (Required)

Specify the field fit length to use when computing the cut length of plain piping for the defined weld type, diameter, and construction requirements. Include the units of measurement, in or mm for example, when defining this value. The length is annotated as A in the figure.

Nominal Piping Diameter From (Required)

Specify the lower diameter bound for which the field fit length applies.

Nominal Piping Diameter To (Required)

Specify the upper diameter bound for which the field fit length applies.

Nominal Piping Diameter Units (Required)

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

Weld Class

Select the weld class for which you want to define a field fit length.

Weld Type (Required)

Select the weld type for which you want to define a field fit length. Valid codelist values are defined in the AllCodeLists.xls workbook on the WeldType sheet in the Codelist Number column. Be careful not to select a shop weld.
