The flow segment type IfcPipeSegmentType defines commonly shared information for occurrences of pipe segments. The set of shared information may include:

It is used to define a pipe segment type specification indicating the specific product information that is common to all occurrences of that product type. The IfcPipeSegmentType may be declared within IfcProject or IfcProjectLibrary using IfcRelDeclares and may be exchanged with or without occurrences of the type. Occurrences of IfcPipeSegmentType are represented by instances of IfcPipeSegment. Refer to the documentation at IfcPipeSegment for supported property sets, materials, composition, and ports.
