Use the following guidelines when modeling guides in CAESAR II:
-
Guides are double-acting restraints with or without a specified gap.
-
You can use connecting nodes (CNodes) with guides.
-
You can define guides using the global system coordinates or using the applicable options in the restraints auxiliary data area.
-
The restraints auxiliary data area displays when you select Restraints on the Classic Piping Input dialog box.
A guided pipe in the horizontal or skewed direction has a single restraint, acting in the horizontal plane, orthogonal to the axis of the pipe.
A guided vertical pipe has X- and Z-direction supports.
CAESAR II computes direction cosines for guides. The software ignores user-defined guide direction cosines.
Guide on Horizontal Pipe with Single Directional Restraint
Node 25 is guided in Z with a gap of 2.5 inches. A single-directional restraint in the Y-direction also exists. Both restraints are rigid. In this example, replacing the guide restraint with a Z restraint is equivalent. |
