Pipe Piece and Pipe Spool Data

Piping

Spooling : Pipe Piece and Pipe Spool Data

The following contains the detailed system-specific information about pipe pieces and pipe spools. It includes the underlying objects and functionality and the database attributes and pseudo-attributes.

PML Methods

The pipe piece manager has no exposed functions.

Pipe Piece Functionality

The functionality of the pipe pieces and pipe spools are:


Function	Description
Invalidate all verified	Set appropriate validation attributes
Query bend activities	Returns bending activities
Delete pipe pieces

Pipe Piece Attributes

The Pipe Piece attributes are displayed below:


Attribute	Type	Default	Get	Set							Remarks
Attribute	Type	Default	Get	User	Spool Mngr	Pipe Mngr	Fab. Mngr	Bend M/C	Weld M/C	Stock Len.	Remarks
Machine Bent	BOOLEAN	False									May not be required
Bending Machine Reference	DBREF						
Bending with flow	BOOLEAN	True						
Auto Welded Start	ENUM						
Auto Welded End	ENUM						
Welding Machine Reference	DBREF						
User Start Excess	REAL	0		
The system should always remember user excesses. Start/End excesses are used only where the relevant start/end flanges are manually welded. The cut length calculation should always user the greater value of the user or bend machine excess.
Bend M/C Start Excess	REAL	0						
User End Excess	REAL	0		
Bend M/C End Excess	REAL	0						
Feed Excess	REAL ARRAY							
Stock Length Value	REAL	0									Holds the stock length that was checked against
Pipe piece verified	BOOLEAN	False									Invisible to user
Pipe piece modified	BOOLEAN	True									Invisible to user
Pipe piece contains bends	BOOLEAN	False									Invisible to user
