Steam line with fixed piping
For steam lines with fixed piping, the same instructions apply to the laying
of the piping as already described.
The following additional notes should be observed:
– The
minimum internal diameter of the steam line
(diameter dependent
on the steam generator) should be applied over the whole length of
the
piping.
– Use exclusively copper pipe or stainless steel (min. DIN 1.4301).
– To minimize the condensate formation (=loss), the steam pipes must
be insulated.
– The
minimum bend radius
for solid pipes is
5 x internal diameter.
– Connection of the steam pipes to the steam distributor and steam gen
erator is effected by means of short lengths of steam hose secured with
hose clamps.
–
Important!
Allowance must be made for a
p
ressure loss of approx.
100 Pa
per meter length or per 90° bend.
