The End Preparation Compatibility Exceptions Rule node (the EndPrepCompatibilityExceptions sheet in the Piping Specification Template.xls or in the Sample Data For End Preparation Compatibility Exceptions Rule.xls workbook) is an optional rule that enables the specification writer to define the exceptions to the End Preparation Compatibility Rule, which is used to determine the compatibility of the end preparation of two mating ends by considering the end standard or the materials category of the applicable fittings. The rule is broadly classified into three categories. The first category is used when the fabricator modifies the pipe stock to assemble in special situations. The second category is used when two ends need to be joined by a connector like nipple for example, and the third category is used when two ends are to be made compatible or incompatible conditionally.

For example, if the End Preparation Compatibility Rule considers end preparation A incompatible with end preparation B, the specification writer can use the End Preparation Compatibility Exceptions Rule to define an exception whereby the two end preparations are considered compatible when the end standard and/or the materials category of both ends are considered. The converse of this example is also true.

As a basis of the rule, the specification writer identifies the paired list of End Preparation, End Standard, and Materials Category values that are compatible (or not compatible) with other specific End Preparation, End Standard, and Materials Category values.

Specifically, this rule can assert one of the following:

  • Carbon steel raised face flanged ends are compatible with stainless steel flat face flanged ends - If the End Preparation Compatibility Rule specifies that raised face flanged ends are compatible with flat face flanged ends, the exceptions are interpreted as combinations of End Standard or Materials Category values that are incompatible.

  • Carbon steel raised face flanged ends are incompatible with cast iron, ductile iron, and plastic flat face flanged ends - Conversely, if the End Preparation Compatibility Rule specifies that raised face flanged ends are incompatible with flat face flanged ends, the exceptions are interpreted as combinations of End Standard or Materials Category values that are compatible.

Based solely on end preparation, butt welded steel pipe is compatible with polypropylene pipe. However, from an engineering standpoint, these pipes cannot be welded together, but would be joined by a flanged pair.

End Preparation End A (Required)

Define the end preparation, such as Small-Groove-Face Lap-Flanged End, for the port applicable to fitting A. Valid codes are listed in the AllCodeLists.xls workbook on the EndPreparation sheet in the Codelist Number column.

Termination Subclass End A (Required)

Define the termination sub-class, for example Flanged, for the port applicable to fitting A.

End Practice End A (Optional)

Define the end practice, such as U.S. Practice, for the end of fitting A.

Materials Category End A / Materials Category Fitting A (Optional)

Define the classification for the materials grade applicable to fitting A. For example, you can use this property to indicate that metallic piping is not to be welded to plastic piping. This property is ignored if you define a value for End Standard End A.

Materials Practice Fitting A (Optional)

Define the industry practice, such as U.S. Practice, for the materials grade applicable to fitting A.

End Preparation End B (Required)

Define the end preparation, such as Small-Groove-Face Lap-Flanged End, for the port applicable to fitting B. Valid codes are listed in the AllCodeLists.xls workbook on the EndPreparation sheet in the Codelist Number column.

Termination Subclass End B (Required)

Define the termination sub-class, for example Flanged, for the port applicable to fitting B.

Termination Class End B (Required)

Define the termination class, such as Bolted, for the port applicable to fitting B.

End Standard End B (Optional)

Define the end standard applicable to the end of fitting B. This property is optional if you define a value for Materials Category, End B.

End Practice End B (Optional)

Define the end practice, such as U.S. Practice, for the end of fitting B.

Materials Category End B / Materials Category Fitting B (Optional)

Define the classification for the materials grade applicable to fitting B. This property is optional if you define a value for End Standard, End B.

Materials Practice Fitting B (Optional)

Define the industry practice, such as U.S. Practice, for the materials grade applicable to fitting B.

Lining Material Fitting A (Optional)

Define the type of lining material, if applicable, to fitting A. Examples include cement-mortar, concrete, epoxy, rubber, or plastic lining.

Lining Requirement Fitting A (Optional)

Define the requirement for lining, if applicable, to fitting A.

Lining Material Fitting B (Optional)

Define the type of lining material, if applicable, to fitting B.

Lining Requirement Fitting B (Optional)

Define the requirement for lining, if applicable, to fitting B.

You can define Lining Requirement without defining Lining Material.

Selection Basis per PCF / Piping Commodity Filter (Optional)

Specify whether the Selection Basis property from the Piping Commodity Filter is to be used to determine whether the two applicable mating ends are compatible. Acceptable values are listed below.

  • Not applicable

  • Pipe stock to be threaded at one plain end - Indicates that one end of the plain end pipe stock is to be threaded, becoming a male-threaded end, and should be considered compatible with a female-threaded end. For example, in some situations for pipe stock, one plain end of the pipe stock, which is incompatible with female-threaded fittings, is threaded during the fabrication process.

    It is recommended that the material description include an embedded label to extract the value of the Commodity Option property from the 3D model. If the value equals the numeric equivalent of a specific value, such as Plain end x Male threaded end or Male threaded end x Plain end, then text, such as Pipe to be threaded at one end, should be appended to the end of the material description.

  • Pipe stock to be beveled at one male threaded end - Indicates that one end of the male-threaded end pipe stock is to be beveled to create a welded joint. For example, in some situations for pipe stock, one male-threaded end of the pipe stock, which is incompatible with beveled fittings, is beveled during the fabrication process to create a weld.

    • The software creates a weld at this joint even though the pipe end at this joint is not a welded end with respect to the piping commodity class data.

    • It is recommended that the material descriptions include an embedded label to extract the value of the Commodity Option property from the 3D model. If the value equals the numeric equivalent of a specific value, such as Male threaded end x Beveled end or Beveled end x Male threaded end, then text, such as Pipe to be beveled at one end, should be appended to the end of the material description.

  • Pipe stock to be grooved at one plain end - Indicates that one end of the plain end pipe stock is to be grooved to create a mechanical joint. For example, in some situations for pipe stock, one plain end of the pipe stock, which is incompatible with mechanical ends, is grooved at the fabrication site to be used to form a mechanical joint for a clamp.

    • The software creates a clamp at this joint even though the pipe end at this joint is not a mechanical end with respect to the piping commodity class data.

    • It is recommended that the material description include an embedded label to extract the value of the Commodity Option property from the 3D model. If the value equals the numeric equivalent of a specific value, such as Plain end x Grooved end or Grooved end x Plain end, then append text to the end of the material description. For example, if the value is something like Plain end x Grooved end or Grooved end x Plain end, append Pipe to be grooved at one end to the end of the material description.

  • Pipe stock push-on bell end to be cut as plain end - For quick installation and sealing, the manufacturer provides plastic pipe stock, such as fiberglass pipe, as Plain End x Push-on Bell End with a purchase length as, for example, 10', and the corresponding fittings as female Socket End. When the pipe stock is connected to pipe stock on the construction site, construction personnel can quickly connect and seal the pipe stock. However, in situations where it is necessary to connect fitting-pipe-fitting, the construction worker cuts the Push-on Bell End of the plastic pipe stock as plain end, and inserts the cut pipe between two fittings.

The following data is required to describe the exceptions to end preparation compatibility on the basis of the piping specification.

Joint Requirement (Conditionally Required)

Specify whether the two applicable mating ends are compatible. Acceptable values are listed below.

  • Ends are compatible - Indicates that the two ends are compatible. If no value is specified, the software considers this the default value.

  • Coupling, connector, or adapter is required for joint - Indicates that the two ends must be joined by a coupling, connector, or adapter.

  • Nipple is required for joint - Indicates that the two ends must be joined by a nipple if the male end represents a fitting. For example, plain end or beveled end of pipe is compatible with a socket-welded fitting. However, a plain end fitting or a beveled end fitting should not be joined directly to a socket-welded fitting. In some cases, such as GRE fittings, a nipple or coupling may need to be inserted between the branch fitting and the first reducing fitting at branch. Likewise, a nipple or coupling may need to be inserted between the first reducing fitting and the second reducing fitting and/or between the second reducing fitting and the third reducing fitting.

  • Minimum length pipe is required for joint - Indicates that the two ends must be joined by minimum pipe length if the male end represents a fitting. For example, plain end and beveled end pipe is compatible with a socket-welded fitting. However, a plain end fitting or a beveled end fitting should not be joined directly to a socket-welded fitting.

Coupling or connector short code / Connecting Part Short Code (Required)

Enter the short code for the coupling, connector, or adapter that is required to form the joint.

Option category for coupling or connector / Connecting Part Commodity Option (Conditionally Required)

Define the categorization of the commodity option.
