Hangers and Supports : Hangers & Supports Configurations and Data Tables : Hanger Configurations

Hanger Configurations store the following data:


DESC	A text description of the hanger configuration
PURP	Set to DATA
GTYP	Hanger build macro suffix
:HCONN	Head connection type (tells the application which type of ATTA is being used for this configuration):
	CATT: Component ATTA
	ATTA: Tube ATTA
:TCONN	Tail connection type (tells the application how to connect to the steelwork or civil):
	NONE: No connection (e.g. sliding)
	BLTD: Bolted connection at back marker p-line
	BOLT: Bolted connection at face of steel using back-marker positions
	SBOL: Bolted connection at face of steel with option of using back-marker or central position
	WELD: Welded connection
:DESINFO	Not used at this release
:DRAINFO	Not used at this release
:MAXLEN	Maximum hanger length where not explicitly defined using hanger length data table (see below)
:MINLEN	Minimum hanger length where not explicitly defined using hanger length data table (see below)
:PSLOPE	Logical flag if pipe is permitted to slope wrt hanger direction
:ASLOPE	Logical flag if steel/civil attachment is permitted to slope wrt hanger direction
:PARHANG	Logical flag if partial build available for ‘parallel’ type configurations

Members

The configuration CATE may own any number of TEXT elements which are used to describe the components used in the hanger. Each component has a TEXT element placed in the correct order in the members list; the description is stored in the STEX attribute.

Hanger Build Macros

Every hanger configuration has an associated build macro which is situated in the DES/SUPP applicationware directory. The macros have the form MHB-{suffix} (see CATE GTYP above). These macros are PML-based, but make use of a specially designed toolkit which lets you create a build macro for almost any hanger configuration.

The toolkit subroutines which you can call in your build macros are as follows:


XHBPCLA	To create, orientate and position a PCLA element
XHBFITT	To reposition fitting once last component is known
XHBHELE	To create, orientate and position a HELE element
XHBHORI	To orientate a HELE element
XHBSCLA	To create, orientate and position an SCLA element
XHBSTART	To start Hanger building
XHBSTART	To start Hanger building
XHBSPAC	To create steel profile spacer between specified hanger elements
XHBHCLN	To check the fitted length on any hanger element

Apart from these, the amount of PML writing you need to do is minimal, although some knowledge of PML and macro writing would be useful. In some cases, the order of element creation means that some additional work needs to be done by the build macro. For an example of this, see the supplied macro MHB-CBWA.

Each of these subroutines is called by using the syntax

CALLSUP <subroutine name> <args>

and requires arguments which enable it to perform its task correctly. Each argument should be enclosed in the delimiters $< ... $> if there is any whitespace. Each macro may also require that a global variable is set, or may in turn set a global variable. For descriptions of RTO values, see the section which details hanger catalogues and datasets.

XHBPCLA:

Arguments


1	PCLA STYP(s)
	For tube ATTAs, single value (quoted if using TANS)
	For component ATTAs, space or / separated list for TEE, ELBO, BEND components (NONE if not applicable)
2	Any other selectors (quoted if using TANS)
3	COMP or TUBE
4	Hanger Direction p-point (for TUBE). This p-point will be orientated to point in the direction of the hanger Rotation Direction p-point (for COMP). This p-point will be orientated to point in the perpendicular direction of BENDs or ELBOs.
5	Angle flag. True if the component has a DDANG which needs to be deduced.
6	Connection/Fitting instructions:
	ATTA: Sets PCLA height to distance P0 to P3 of ATTA
	FITH: Sets PCLA height to distance HH to HT
	FITP: Sets PCLA height to half pipe OD
	CONN: Does not set PCLA height
7	Spec from which to select component:
	INSPEC: Select from current HSPEC
	PSPEC: Select from attached pipe PSPEC
	<gid>: Select from explicit specification

Globals used

None

Globals set


!!CDSNHB.RTOVAL1	Derived RTO value at P1 end
!!CDSNHB.RTOVAL2	Derived RTO value at P2 end


1	HELE STYP
2	Any other selectors (quoted if using TANS)
3	HELE GTYP. Unique WORD attribute used to identify HELE for later operations
4	GTYP of element which will be at the arrive end of the new HELE
5	GTYP of element which will be at the leave end of the new HELE
	N.B. If argument 4 identifies an element which occurs later in the hanger's members list than argument 5, this will cause the new element to be created in ‘backwards’ mode. This can be very useful in some circumstances
6	Arrive p-point/Leave p-point (e.g. 2/1)
7	Connection/Fitting instructions:
	FIT: Fit the HELE into the available space (by setting HEIGHT attribute)
	CONN: Connect the HELE to the previous element (or HH/HT)
	DIST: Set the HELE at a specified distance from the previous element
	PROP: Set the HELE at a specified proportional distance between the previous and the next elements
	DIST and PROP both have the format <keyword> <value> <p-point> (the p-point designation is optional and defaults to P0)
8	Angle flag. True if the component has a DDANG which needs to be deduced.
9	Specification from which to select component:
	INSPEC: Select from current HSPEC
	PSPEC: Select from attached pipe PSPEC
	<gid>: Select from explicit specification

Globals used


!!CDSNHB.RINS1	Rod insertion length at P1
!!CDSNHB.RINS2	Rod insertion length at P2

XHBHORI:

Arguments:


1	HELE GTYP
2	Mode FORW or BACK
3	Connection/Fitting instructions
	FIT: Fit the HELE into the available space (by setting HEIGHT attribute)
	CONN: Connect the HELE to the previous element (or HH/HT)
	DIST: Set the HELE at a specified distance from the previous element
	PROP: Set the HELE at a specified proportional distance between the previous and the next elements
	DIST and PROP both have the format <value> {<p-point>}
	The default p-point is P0.
4	Angle Flag to direct component arrive/leave

XHBSCLA:

Arguments


1	SCLA STYP
2	Any other selectors (quoted if using TANS)
3	Fit flag. True if SCLA is to be fitted into the available space.
4	P-point to orientate towards previous component. The subroutine will attempt to align the PA/PL, but if this in insufficient, then it will use this p-point. Default orientation is determined by argument 5.
5	Default orientation:
	TUBE: Pipe flow direction
	STEEL: Steel direction (can be SCTN Y or X direction depending on hanger Tail connection type)
6	Any other selectors (quoted if using TANS):
	INSPEC: Select from current HSPEC
