Configuration of the Hangers Design Templates

When the MDS application creates a hanger of a given configuration, it copies the required hanger template. In order for the application to know which template it should copy, a specific naming convention is used. Each hanger configuration has a name (for example, FH01, VH01). As explained in the overview each zone represents a single hanger configuration. The names of the zones have the following formats:

/MDS/FH**
is used for fixed hangers (for example, /MDS/FH01).

/MDS/VH**
is used for variable hangers (for example, /MDS/VH01).
(** denotes a two digits sequence number)

Each zone owns several REST elements. Each REST represents a hangers size for that configuration. The name of the REST templates has the following format:

/MDS/FH**/pipe_size_in_mm

For example, a REST having the name /MDS/FH01/100 represents a template for a hanger with a FH01 configuration, used for a 100mm pipe. In some cases the hanger designer may need different hanger sizes for the same pipe size.

A good example of this is when a hanger is attached to a welded elbow lug. The lug may have a range of holes sizes. So, although the hanger configuration type is the same and the pipe size is the same, a lug with a larger hole will require a larger pin and a hanger with larger rods. This is handled by adding a one-letter suffix to the name of the REST and is compatible with AVEVA’s standard naming convention used in the hangers catalogue for rod sizes. For example, suffix A is used for an M6 rod size, B for an M8 rod size A typical template name for such a hanger may be: /MDS/FH01/100/A. This template is for hangers with the FH01 configuration, connected to a 100mm pipe and having M6 rod size.

For further information about AVEVA's naming convention, refer to the Conventions for Catalogs and Specifications Guide. The range of sizes available for a given hangers configuration, as well as other specific configuration data, is set when the hangers feature of the MDS application is used for the first time in a session. The application then scans the MDS hangers template site: /MDS/HANGERS, reads the zones attributes, and saves it in memory for later use. The range of available hanger sizes for each configuration is determined from the restraints elements below the zone.

Each hanger has its own specific design characteristics, as defined in the MDS Hanger Data form (refer to MDS Hanger Data Form).
