This table is used to identify the pressure/temperature pairs used from each segment for analysis under deadweight, hot conditions, cold conditions, and wind loading conditions.

This table allows you to specify the pressure/temperature pair used under each of the analysis conditions for each segment. The simplest case uses the same pressure/temperature from each segment for each of the different analysis conditions. A more complicated situation is also allowed where some segment attribute dictates that a given set of pressure/temperature pairs should be used for that specific segment.

The format of a single entry in this table is:

TABATT, FLAG, VAL, DWT, HOT, COLD, WIND

where:

TABATT

table, column pair identifying the attribute from the segment to be compared with VAL. The first table entry contains 0,0 for this item. This defines the default set of T,P pairs to be used. If there are no other table entries, the same T,P pairs will be used from each segment for all analysis conditions.

FLAG

set to 1 if VAL is a code list number set to 0 if VAL is not a code list number

VAL

value of the database attribute triggering use of the following T,P pairs for a segment

DW

Pressure/temperature|load set|pair for deadweight analysis of this segment

HOT

Pressure/temperature|load set|pair for hot condition analysis of this segment

COLD

Pressure/temperature|load set|pair for cold condition analysis of this segment

WIND

Pressure/temperature|load set|pair for wind analysis of this segment

The pressure/temperature attributes are the piping designer's responsibility.
