Typical Specifications : Selectors and Pointers for Piping Components : Selectors

There are very few constraints on the SELEC questions, and the order in which you list them, when defining SPECs for piping components. The following headings should meet most of your requirements:

Pbore integer

Specifies the bore of p-point integer. For multiway components (such as a Tee), more than one PBORE SELEC may be specified (PBORE1, PBORE2 etc.).

PConn integer

Specifies the connection type of p-point integer.

Note:

See P-Point Zero: A Special Case for important information about the use of the special cases PBORE0 and PCONN0 which may be applied to the preceding SELECs.

SType

Defines the Specific Type of the component; it is effectively a subdivision of a GTYPE. For example, a component of GTYPE VALV may have an STYPE GATE, GLOB, CHEC etc.

ANGle

Defines the required angle of an ELBO or BEND, when DDANGL has been used in the component pointset (PTSET). The answer to this SELEC question in an SPCOM may be a single value (e.g. 90.0) or a range of values (e.g. 45.0,90.0).

RADius

Defines the required radius of an ELBO or BEND, when DDRADI has been used in the component pointset (PTSET). May be a single value or a range.

TEMperature

Defines the operating temperature.

PRessure

Defines the operating pressure.

RATing

Defines the pressure rating.

SHOP

Defines whether the component is intended for shop fabrication (SPCOM answer TRUE or SHOP) or on-site assembly (SPCOM answer FALSE or SITE).

In addition to the standard SELEC headings, you may use any word (up to four letters), with or without a numeric qualifier, to define your own questions. For example, if you wished to include a range of colour-coded reducers in your Catalogue (perhaps having a base colour and a marker colour to indicate suitability for particular types of use), you might include the questions COL1 and COL2 as SELEC headings in the Specification for TYPE REDU. The SPCOMs containing the answers to these questions will be considered by the selection process if the appropriate option is specified in your design module command; for example

SELECT NEW REDU ... WITH COL1 RED WITH COL2 BLUE

If COL1 and/or COL2 are omitted, the default colours (answers) will be used.
