3 Threaded Joints
General
Mostly are used cutting ring joints according to DIN
3861 with 24
_
inside cone, made of steel or stainless
steel.
Alternately it is possible to use joints with sealing cone
and O--ring.
Cutting ring joints with additional DSW sealing ring are
applied in places where an even better tightness and
higher reliability are demanded.
E.g. if joints are no longer accessible at a later point of
time.
These joints can also be mounted on site.
Up to an outside diameter of 10 mm, the pipes in joints,
which are screwed into devices, can be directly
mounted.
Joints from Ø 12 mm up and all couplings in free con-
duits are to be pre--mounted after fastening the union
socket in the vice jaw.
NOTE
During further mounting attention is to be paid that pre--
mounted parts are each used as a unit.

Preassembly
1. Lubricate cutting ring and the thread of coupling
and swivel nut well with oil (do not grease).
NOTE
Oiling can be left out in case of galvanised threaded
joints with clear antifriction coating.
2. Slide the swivel nut on and then the cutting ring
with the cutting side towards the pipe tail end (Fig-
ure 13).
NOTE
If the ring cannot be slid over the tail end or only with
difficulty, then reduce the pipe tail end with a file, and
clean the pipe again carefully!
