PVC-U Solvent Cement Jointing

Solvent Cement Fittings in rigid PVC-U can be glued on PVC-U pipes provided that the pipe dimensions comply with ISO 727, UNI 7442/75, DIN 8063, NF T54-027 for metric range and BS3505-3506 for B. solvent cement. A strong dense-type glue is recommended, especially for jointing large diameters, where the ovalisation effect may cause a considerable slack. For a perfect sealing this slack should never exceed 0.6mm with a dense type glue and 0.3mm with a fluid type glue. For a perfect sealing strictly follow the glue manufacturer’s instructions:

• a) Cut the pipe squarely, remove burrs, chamfer pipe end and roughen mating surfaces with a glass paper. Then, using a clean cloth wipe over with cleaning solvent.
• b) Apply an even coating of glue to both socket and spigot.
• c) Push spigot into socket immediately (1-2 minutes)
• d) Wipe off excess glue.
• e) Verify the correct alignment of pipe and fitting.

Leave joint undisturbed for the time required by the glue manufacturer and in any case allow 24 hours at normal room temperature (20°C) before applying pressure.
