Figure 1
shows the versatility of the steam
pipe / steam hose steam delivery system. It
also indicates where and how condensate
traps / condensate separators should be
used. If the steam pipe slopes such that the
steam connection is lower than the far end of
the pipe, this indicates that a reverse slope
steam pipe is required. This is fitted with a
drain point to allow condensate to be taken
away to a convenient drain.
Figure 2
shows recommendations on how to
space one or more steam pipes in a
horizontal duct.
Figure 3
shows recommendations on how
steam pipes should be spaced in a vertical
duct
Figure 4
shows mounting details for 35 and
54 Ø steam pipes
NB. The duct should be clear of obstructions,
transformations and bends until the steam
has been absorbed into the airflow. A guide
to calculating this distance is available from
Vapac – Part Number 0411047.
