JOINTING:

A wide range of UPVC Fittings are available. They are economical, durable, leak proof, easy & quick for the connections. These Fittings include Coupling Sockets, Elbows, Tees, end Caps Flanges, (45 & 90) and reducers. These Fittings are available in various sizes for different pressure classes of Pipes. Confirming to BS, PS, ASTM & other international Standards.

POPULAR UPVC PRESSURE JOINTING SYSTEM

The following jointing systems are available,

  • Solvent Cement Joint
  • Z Joint/Rubber Ring Joint

SOLVENT CEMENT JOINTING SYSTEM
Procedure for Solvent Joint Installation:

  • Chamfer the Pipe and at a angle of 15 or 20 to an extent for 0.5mm length
  • Apply solvent cement thoroughly & evenly over spigot end and inside of socket
  • Ensure that both spigot & socket are thoroughly clean
  • Inset the pipe quickly into the socket
  • Hold for a while say 4-5 minutes
  • Wipe all excessive solvent cement with a cloth
  • Leave for 24 hours before pressure testing

THINGS TO REMEMBER
Knife or half round coarse file, natural bristle, primer, application cane solvent cement & tools tray are required for solvent cement jointing.

Z” JOINTING SYSTEM
Procedure for installation:

  • Ensure that the mating areas of spigot and socket are thoroughly clean. This is extremely important for the correct positioning of the rubber ring during assembly.
  • Set the rubber ring into the grove, pushing it firmly in as far as it goes all the way round. The opening in the rubber ring must face backwards.
  • Assess the full socket depth by simply measurement & mark spigot accordingly.
  • Accurate axial alignment of the spigot & socket prior to jointing is important, hand feed spigot into rubber joint until resistance from the inner seating section is felt.
  • Stop at the entry mark (13-25mm) from the end of the socket to cater for potential expansion & contraction.
  • Make sure that the pipes to be jointed are aligned correctly against each other.
