care. Allow 4 hours if the jointed pipe lengths are to be laid in a trench.
Allow 8 hours to elapse before applying working pressures or 24 hours for test pressures. With pipe
sizes up to 50mm, it is possible to reduce this time. Allow 1 hour for each 3.5 atmospheres of
pressure.
Brushes must be clean and dry before commencing solvent welding. Brushes must be thoroughly
cleaned after use by washing in cleaning fluid. Do not dilute solvent adhesive with cleaning fluid. Use
Solvent adhesive and cleaning fluid in a well-ventilated area. Keep away from naked flames and do
not smoke.
Always replace lids of containers. In any event, attention is drawn to the instructions printed on the
containers.
When laying continuous runs of pipe, joints may be made quicker than the setting times advised
above.
The joint will not be disturbed with long lengths, providing that the pipe is not twisted or the previously
made joint lifted out of place.
Rubber Ring Joints
Ensure that the spigot and socket are free from dust, grit, grease and as dry as possible. Insert pipe
into the socket without seal ring in place and mark pipe when it is fully inserted. Place seal in groove of
socket ensuring that seal is correct way round. Anger seal rings should be fitted with tapered section
facing the outside of the socket.
Apply jointing lubricant to the chamfer and the end of the spigot of the pipe or fitting only. Push the
pipe firmly into the socket up to the insertion mark previously made. If an expansion gap is required
the pipe is then pulled back by the desired amount.
