About Piping Connections

Fittings are chosen based on current spec file, and the joint settings in the project. The spec file provides the list of available fittings, the priority order in which compatible fittings are selected from the list (if there are multiple options), and the branch table.

An endcode describes the open end (port) of piping and equipment nozzles. For example, the endcode of a buttweld elbow is BV (for Beveled). The endcode of an equipment nozzle is typically FL (for Flanged).

You can use the Properties palette to view the endcodes of piping and nozzles in the drawing. You cannot change the endcode using the Properties palette.

In general, you do not manipulate endcodes directly. They are a Read-only property of the part used in the pipe spec or the equipment nozzle.

Default Endcodes    
Endcode Description Example Joint (Match)
PL Plain End, Socket Male Socket Weld (SWF)

LLP Lined Lap  
LUG Lug Flanged (FL)
BELL Bell Bell and spigot (SPIG)
SPIG Spigot Bell and spigot (BELL)
TAP Tap Tap (PL)

Pipe adapts to different end connections. Plain, beveled, threaded male, and grooved end types are all compatible and adjust to match the joint. For example, if a threaded elbow is connected to a pipe that has a Port Property of PL for EndType1, the pipe end type connects as THDM.
