The Piping Generic Data Bolted sheet in the AllCommon.xls workbook defines generic data for bolted piping ends.
Nominal Piping Diameter
Type the nominal piping diameter for the bolted end.
Nominal Diameter Units
Specify the units for the NPD column. For example, type mm or in.
Type the pressure rating code for the bolted end. This property defines the envelope of pressure to which the bolted end may be subjected. Valid codes are listed in the AllCodeLists.xls workbook on the Pressure Rating sheet in the Codelist Number column.
Type the end preparation code for the bolted end. Valid codes are listed in the AllCodeLists.xls workbook on the End Preparation sheet in the Codelist Number column.
Type the end standard code for the bolted end. Valid codes are listed in the AllCodeLists.xls workbook on the End Standard sheet in the Codelist Number column.
Flange Outside Diameter
Type the flange outside diameter of the bolted end.
Type the distance from the outermost face of the flange to the back surface of the flange on which the nut rests. This distance includes any projections that the flange may have, such as raised-face, only if the manufacturer's data includes any projections. The flange thickness includes the thickness of the loose flange used, but does not include the wall thickness of the pipe or stub end for lap-flanged ends. In terms of ASME B16.5 (1996), this value is considered the minimum flange thickness.
Flange Thickness Tolerance
Type the plus tolerance for the flange thickness. For example, ANSI B16.5 (1996) specifies the flange thickness tolerance as 1/8" for NPD 18" and smaller, and a tolerance of 3/16" for NPD 20" and larger.
This value is required for computing bolt lengths, when you (the specification writer) prefer to express the flange thickness tolerance explicitly and independently of the stud or machine bolt extension.
Flange Face Projection
Type the value that represents any projections that the flange may have. An example is a raised-face flange.
Raised Face Diameter
Type the raised-face diameter of the bolted end, if applicable, to raised-face flanged ends. This value is required to compute the outside diameter of the gasket and the inside diameter of the gasket.
Flange Groove Width
Type the groove width of the bolted end, if applicable, to groove-flanged ends. This value is required to compute the outside diameter of the gasket.
Type the distance from the outermost surface of the bolted end to the seating surface of the gasket. This column has a value only for small groove flanged, large groove flanged, small female flanged, large female flanged, small groove lap flanged, large groove lap flanged, small female lap flanged, large female lap flanged, ring type joint flanged, and mechanical joints. This value represents the groove depth for ring type joint flanged ends.
Bolt Circle Diameter
Type the diameter of the circle of bolt holes on the face of flange. This property applies only to circular drilling templates.
Quantity of Bolts Required
Type the number of bolts required for the bolted end.
Type the diameter of the bolts for the bolted end.
Body Outside Diameter
Type the outside diameter of the body of the fitting at the bolted end.
You can still choose to define the body outside diameter with the piping commodity part data (or piping specialty part data or instrument part data) for certain fittings. This actual body outside diameter is required for rack piping to match the bottom pipe of the adjacent straight runs, not only for aesthetic purposes, but also to ensure that if the body portion of the component rests on steel, the correct centerline is maintained. Using inaccurate data, in some cases, will cause false interferences to be reported, and in other cases, leave diameter mismatches with adjacent piping.
Drilling Template Pattern
Type the drilling pattern code for the bolted end. This code represents the arrangement of bolt holes at the bolted end. Valid codes are listed in the AllCodeLists.xls workbook on the Drilling Template Pattern sheet in the Codelist Number column. For pictures of common drilling patterns, see Bolt Hole Patterns.
Bolt Pattern Length
Type the bolt pattern length for the bolted end.
Bolt Pattern Width
Type the bolt pattern width for the bolted end.
Bolt Pattern Offset
Type the bolt pattern offset for the bolted end.
