1. Saw the pipe rectangularly through and take off
burrs.
2.
It will be most easy
for you to saw the
pipe rectangularly
through by means
of the pipe sawing
mechanism shown.
NAME:BAV 6/42
(for pipes of 6-42 mm
OD).
NOTE: Do not use pipe cutter!
The pipe will be cut over slantingly
and there will be burrs inside as
well as outside the pipe end.
3.
Lubricate thread as well as cut-
ting- and key ring with oil (not
grease). Now push the pipe nut
and the ring over the pipe end as
shown on the drawing.
If the cutting- and key ring can-
not or can only just be pushed
over the end of the pipe, do not
entlarge it, but file the pipe end.
Mounting in Connection Socket
A marking thread on
the compression nut
will make it easier for
you to observe the
turns prescribed.
5. (NOTE: The pipe must nut turn at the same
time).
The cutting- and key ring will get hold of the
pipe, and now it is unnecessary to press the pipe
further. For the final feed, give the compression
nut another turn of approximately 3/4. By doing
so, the ring will cut into the pipe and reveal an
apparent belt.
6. Pipes of a large outer diameter and all
connections in free pipings are mounted
in a vice of practical reasons while you
are fastening the connection socket. The
screw spanner must have a length ap-
proximately 15 times as long as the width
of it. (Lengthen it by means of a pipe, if
necessary). Proceed according to point
4.
When using series connection sockets, be
aware that the pipe ends go into
the same inner conus as the one
in which the mounting in the vice
was carried out. The final tightening
will be simplified by loosening the
compression nut a little, so that the
wearing surfaces may be supplied
with a little oil.
7.
After the final feeding, loosen
compression nut and check
that there is an apparent belt
before the cutting. If not - wring
the cutting- and key ring a little
extra.
Apparent belt
8. It does not matter if the cutting- and key
ring can be turned on the pipe end.
9. REMOUNTING
After each loosening of the connection, the
tightening of the compression nut may be
done without any lengthening with a pipe
and without any violent effort.
10.
The straight pipe end,
which goes into the
screwed connection, must
have a length of at least
2 lengths of the compres-
sion nut (H).
If the pipings are longer
or more weighted, you
will have to mount a pipe
fitting.
4. At first screw up the
compression nut by
hand until it has got
contact with the cut-
ting- and key ring.
Then press the pipe
wholly up to the inner
conus and give the
compression nut a
turn of app. 3/4.
