Installation Jointing - Solvent Cement Weld Joints


To make good solvent weld joints, the following steps are recommended:

  • Before jointing check that the spigot has been cut square and all deburr at the both inner and outer edges should be remove with a knife or suitable device.
  • Mark the spigot with a pencil of marker at a distance equal to the internal depth of the socket.
  • Using the clean cloth, wipe away all loose dirt and moisture from bonding surfaces, if necessary use recommended cleaning fluid for successful joint. Do not attempt to solvent weld wet surfaces.
  • The solvent cement should be thoroughly stirred before use.
  • Using a clean brush apply a thin, uniform coat of solvent cement to the both internal surface of socket, and then to the external surface of the spigot up to the mark.
  • Immediately push the spigot straight (no twisting) into the socket as far as the mark. Hold the jointing in this position for 20 to 30 seconds depending upon ambient temperature.
  • Allow at least 30 minutes for each joint to set without disturbance. Allow up to 4 hours, before subjecting the joint to stress.
  • Do not pressure test the joint for at least 24 hours.
