Bolt Specifications
Pipe Specifications have a reference attribute BSPEC, which can be set to a specification containing bolts. Bolts will be selected from the Bolt Specification, if the BSPEC is set, or from the Piping Specification of the flanged component, if it is not set.
For bolting across Specification breaks, bolts will be selected from the second Specification if they cannot be selected from the first Specification. The first Specification is defined as the gasket Specification if a gasket is present, otherwise it is defined as the downstream Specification.
In the event that bolts are included in vendor supply, for example, an orifice flange assembly, a null BLTREF of CATREF indicates that no bolts will be output for that joint.
