1.3.2.4 Permitted gas temperature depending on temperature code of FLSE100
Case 1 (see → p. 14, Table 1):
Outside the pipeline an explosive atmosphere exists under normal atmospheric conditions,
which is categorized as area zone 1 or zone 2. Inside the pipeline the process conditions
can be different from atmospheric conditions. Process conditions can be in the range as
specified on the tag of the FLSE100. In this case the gas or gas mixture can be combus
-
tible but must not be explosive.
Case 2 and 3 (see → p. 14, Table 1:
On both sides of the pipeline an explosive atmosphere exists under normal atmospheric
conditions. The pipe wall separates different zones, i.e. inside the pipe is zone 1 and
outside the pipe is zone 2. This means the gas temperature and the line pressure must not
exceed the specified ambient values.
NOTICE:
The pipe wall can separate different hazardous areas (zones).
