2.2.2 Horizontal Pipe Mounting – Gas
To ensure the instrument lines contain only gas, install Torbar
with the instrument connections
above
the centre line of the
pipe, at least 5 ° above the horizontal – see Fig. 2.3.
2.2.3 Horizontal Pipe Mounting – Liquids
To ensure the instrument lines contain only the process liquid,
install Torbar with the instrument connections
below
the centre
line of the pipe, at least 5 ° below the horizontal – see Fig. 2.4.
2.2.4 Horizontal Pipe Mounting – Steam
To ensure the instrument lines contain only steam, install Torbar
with the instrument connections
at or below
the centre line of the
pipe – see Fig. 2.5. Filling tees or condensate pots should be
fitted as appropriate.
2.2.5 Vertical Pipe Mounting – All Applications
Install only Torbar options PNV and RNV in vertical pipelines.
To ensure an equal head of gas, liquid or steam in both
instrument lines, Torbar options PNV and RNV are designed so
that the instrument lines are in the horizontal plane when the
Torbar is installed (see Fig. 2.1).
Any lateral-mounting angle is suitable – see Fig. 2.6.
