The Port Alignment Rule node (the PortAlignment sheet in the Piping Specification.xls workbook) defines the allowable joint deflection. This rule is used:
When a branch connects to a sloped header. Should the branch be trimmed by adding more weld material or by trimming the branch end?
To provide flexibility in male/female mechanical connections such as underground bell and spigot.
To trim the welded end of a flange at a nozzle to align with a sloped pipe.
This sheet contains all the default values that the software is to use in the piping specification. You can define exceptions for a particular piping materials class in the Port Alignment Per Spec under the Piping Materials Class Rules node.
Acceptable Alignment Tolerance (Required)
Specify the maximum angular variation. This may be between the branch centerline and the header centerline, between the bell and spigot, or between the flange and the nozzle. Be sure to include the unit of measurement when defining this value, for example, 1.5deg.
End Preparation (Required)
Define the end preparation for the port alignment being defined. Valid codes are listed in the AllCodeLists.xls workbook on the EndPreparation sheet in the Codelist Number column.
Method of Trimming (Required)
Define the method of trimming. Valid codes are listed in the AllCodeLists.xls workbook on the MethodsOfTrimming sheet in the Codelist Number column.
Nominal Piping Diameter From (Optional)
Specify the pipe diameter lower bound for which the port alignment applies.
Nominal Piping Diameter To (Optional)
Specify the pipe diameter upper bound for which the port alignment applies.
Nominal Piping Diameter Units (Optional)
Specify the unit of measurement, in or mm for example, for the values in the Nominal Piping Diameter From and Nominal Piping Diameter To columns.
