The' Equipment Sequence Number (ZZZZ) is a four-character sequence number. If the
system identifier changes, the sequence number can be used again. For example, the
equipment identifier TNK-51-5001 is a valid number even if the sequence number is the
same as TNK-13-5001. The different system number provides the necessary uniqueness.
1.2.2 Line Numbering
The line numbering system is as follows:
Il-J JZZZZ-M-NNN-00-TT
Where :
0

II represents the Line Service Code (see Table 1-3).
JJ represents the System Number (see Table 1-1).
ZZZZ represents the Line Sequence Number (starting at 5000).
M represents the nominal line size in inches.
NNN represents the Material Specification, which consists of the last three digits of the
Construction Specifications Institute (CSI) specification for the material (e.g., 105 for
1 5 105) (see Table 1-41.
00 represents the Insulation Type Code (if any) (see Table 1-5). insulation thickness,
etc., shall be called out in the specifications.
TT represents the Heat Trace Type Code (if any); for Silo 3, the only heat trace type is
electric traced, or "ET."
Thus an appropriate line number for a 1 %"; 15105 instrument line, with no insulation or
heat tracing would be:
IA-405001-1 %"-lo5
An appropriate line number for a domestic water line, system 51, 1 %", specification
1 5 103, insulated, and electric heat traced would be:
DW-515011-1 H "-1 03-HC-ET
