Hanger Connection Types Example

TD (Tail-Dominant)

PD (Pipe-Dominant)

UD (Up/Down)

PP (Pipe-Parallel)

The hanger and support surface are maintained perpendicular to each other. Components that connect to the pipe are expected to rotate to suit this condition.

(This case is only expected to be used with, for example, rigid struts).

The hanger and pipe are maintained perpendicular to each other. Components that connect to the support surface are expected to rotate to suit this condition

The hanger is expected to hang in the vertical (up/down) direction. Components attached to the pipe and support surface are expected to rotate to maintain the hanger verticality

This is a special case where pipe supports are intended to be used in longitudinal restraint conditions. The hanger and pipe are expected to run parallel to each other and the hanger is perpendicular to the support surface.
