Pipe supports serve two purposes in a jacketed system:
-
Locating spacer or restraint details between the internal and external piping.
-
The normal support attachments for the jacket piping, for example: shoes, anchors, dummy legs, and so forth, are placed and extracted with external piping.
Normal Supports
Use the Hangers and Supports task to place supports and hangers on the jacket pipeline just as you would a standard pipeline. Be careful when placing the supports that you only select the jacket pipeline. Otherwise the support will connect to the core pipeline and cause interference between the support and the jacket pipeline. See the Hangers and Supports Help.
