The pipe parts catalog contains pipe parts in thousands of sizes. The Piping domain includes the following part types:
- Connector
- Coupling
- Cross
- Elbow
- Endcap
- Offset wye (lateral)
- P-Trap
- Takeoff
- Tee
- Transition
- Wye
- Undefined
Pipe parts catalogs are organized differently, depending on the profile in which you run AutoCAD MEP 2022 toolset. Catalogs in the US Imperial and US Metric profiles are organized based on material type:
- Cast iron
- Copper
- Ductile iron
- Plastic
- Steel
Fittings in these categories are grouped by connection type (such as threaded). The following example shows the cast iron parts catalog.
Pipe parts catalog for cast iron pipe parts
Catalogs in the Global profile are organized by type and outside diameter, as follows:
- Commercial pipe: Pipe and fitting dimensions based on commercial steel pipe; also includes plastic pipes, such as PVC.
- Ductile iron: Pipe and fitting dimensions based on commercial iron pipe
- Tube and fitting dimensions based on copper tubing
- Placeholder: Dimensionless 1-line parts used for preliminary pipe runs; can be converted to other pipe types
The following example shows the pipe MvParts catalog under the Mechanical chapter.

Each pipe directory in the Global profile consists of fittings common to that pipe type. Pipe fittings are typically classified by part type, connection type, and pressure rating. The next example shows a directory structure for a class 3000 socket weld coupling.
Couplings under Pipe catalog
Pipe fittings and connectors, unlike pipe segments, have specific connection types. Pipe connectors, such as flanges, are treated as separate objects in the actual construction. For example, when a flanged elbow is connected to a pipe segment, a separate flanged connector is added to the pipe segment. You can account for all the connectors in the system and create schedules for them. The connector engagement length (CEL) is also used to accurately represent pipe lengths and joint locations in the system.
