The Automated Bolt Selection at Spec Break Rule defines (the AutoBoltSelectionSpecBrkRule sheet in the Automated Selection of Parts at Spec Break Rules workbook) an optional rule that enables the spec writer to define the preferred bolting (that is, the bolts, nuts and washers) to be used at spec breaks when the default bolting for the applicable piping materials classes is different.

This rule:

  • Automatically determines the bolting to be used at a spec break when the default bolting of spec A differs from the default bolting for spec B.

  • Automatically determines the bolting to be used at a spec break when a third bolt is required at the spec break. For example, neither the default bolting of spec A nor the default bolting for spec B represent the proper bolting to be used at the spec break.

The preferred bolting is determined independently of the sequence of the bolted ends in the piping specification of the bolted ends in the 3D model.

The software selects the bolting from each piping materials class and compares them. If the bolt sets differ, the software selects the preferred bolting for the spec break on the basis of this rule that is independent of either piping materials class.

In general, the stronger bolt should be selected at a spec break. However, the strength of the bolt is not always the determining factor. If one of the fittings at the bolted joint is plastic, the weaker bolt may be the appropriate bolt to use. The materials engineer must consider the relative strength of the bolts to be used within the piping specification, and must take into account whether the stronger (or weaker) bolt is to be used on the basis of the materials category of the two flanged fittings forming the bolted joint.

Likewise, one piping materials class might not always be the best choice when being compared with a second, specific piping materials class under certain operating conditions (for example, where consideration of the temperature might be required).

Although this rule provides an automated selection for the piping designer, and results in the preferred bolting being selected, it does require that the specification writer pre-define the bolting selection for all possible spec breaks.

If you define any records using this rule, the software only uses this spec break rule to check for the connection parts at the spec break condition. You must define all the possible combinations or records that can be encountered in the model for the spec break condition. If an entry is defined in the rule, the software checks the rule. If at least one entry is defined in the rule, then the software does not check for the connection parts in the selection filters as it would in the default behavior.

If you are using this rule, and any combination or record is missing at the spec break, the software generates a ToDo List item and writes the following error in the Error log file:

Spec break Rule record does not exist for the data

For example, you define the automated bolt selection rule for two-inch NPD but do not define automated bolt selection for four-inch NPD. When you place a four-inch spec break bolted joint, the reference data returns an error even when the four-inch data is defined in the bolt selection filters of both specs.

The preferred bolting is selected from the piping specification on the basis of the following data:

Piping Materials Class, End A (Conditionally Required)

Type the unique name of the piping materials class for one end of the bolted joint.

Revision Number, End A (Conditionally Required)

Type the revision number of the piping materials class, as assigned by the spec writer, for one end of the bolted joint. The combination of the piping materials class and the revision number will uniquely identify the data for this rule.

Nominal Piping Diameter, From (Conditionally Required)

Enter the value that represents the lower bound of the nominal piping diameter for which the bolting selection data applies.

The range query for the nominal piping diameter is based on the value from the 3D model being greater than or equal to the lower bound, because the ranges for this rule are considered to be mutually exclusive. In other words, this range is based on discrete values. The upper bound of one range will not have the same value as the lower bound of the subsequent range.

Nominal Piping Diameter, To (Conditionally Required)

Enter the value that represents the upper bound of the nominal piping diameter for which the bolting selection data applies.

The range query for the nominal piping diameter is based on the value from the 3D model being greater than or equal to the lower bound because the ranges for this rule are considered to be mutually exclusive. In other words, this range will be based on discrete values. The upper bound of one range will not have the same value as the lower bound of the subsequent range.

Nominal Piping Diameter Unit of Measure (Conditionally Required)

Select the select list (codelist) value that represents the unit of measure for the nominal piping diameter range.

If the Nominal Piping Diameter Equivalence rule exists in this Piping Specification, the data for this rule is determined on the basis of the value for the nominal piping diameter in the primary system of units, which is represented by the active size defined by the piping designer in the 3D model. Otherwise, the data for this rule is determined on the basis of the nominal piping diameter in the secondary system of units as defined by the Nominal Piping Diameter Equivalence rule. Consequently, it is not necessary for the spec writer to define the data for the rule in both nominal piping diameter systems of units. Nor will it be necessary for the piping designer to define the active size in the system of units used by the spec writer.

The unit of measure types for Nominal Piping Diameter is permanently restricted to inches and millimeters.

Maximum Temperature (Conditionally Required)

Enter the value that represents the maximum temperature for which the bolting is applicable.

If piping materials class A and piping materials class B form a spec break; this rule may specify that the preferred bolting to be used is the one from piping materials class B. However, there may be situations where, for example, the bolting in piping materials class B should be used when the temperature is less than 500º F; but the bolting from piping materials class A should be used when the temperature exceeds 500º F.

Maximum pressure (Conditionally Required)

Enter the value that represents the maximum pressure for which the bolting is applicable.

Bolting Data Determined by the Piping Specification

Based on the criteria values that you defined above, the software uses these bolt values:
