Solvent Weld Joints
There are relatively few fittings which
need to be solvent jointed. The correct
sequence for solvent jointing is as follows
(also see Figure. 12):
1. Ensure that the pipe has been cut
cleanly and at right angles to its axis.
2. Clean swarf and other dirt from the
pipe end.
3. Wipe the inside of the socket and the
spigot of the pipe or fitting to remove
any surface dirt.
4. To remove grease and prepare
the surfaces of the socket and
spigot, clean both surfaces with
Osma Degreasing Cleaner No 1
(4D380) applied liberally on a clean
nonsynthetic rag or absorbent paper.
5. Apply one coat of Solvent Cement No
2 (4D383) evenly, using a clean brush,
to both the mating surfaces, stroking
the cement along and not around the
surfaces.
6. Immediately insert the spigot straight
into the socket until the full socket
depth is reached, hold for 20–30
seconds and remove any surplus
cement from the mouth of the socket.
7. Each solvent joint must be completed
within 1½ minutes.
8. The joint may be handled after 10
minutes and commissioned after 24
hours.
Do not thin Solvent Cement or Solvent
Cement Filler. As these cements are
solvent based it is essential to observe
the normal precautions for solvents (see
‘Safety’ page 54).
Boss Socket Connections
These may be made on the top of sealed
inspection junction covers using either
a 32mm or 40mm Boss Socket Adaptor
(4S398/399).
Make the connection by drilling out the
unperforated boss socket on the fitting
using a standard 54mm hole cutter.
Solvent weld as described in ’Solvent
Weld Joints’, pushing the adaptor the
full depth along the keyway of the boss
socket.
