INSTRUCTION FOR PVC APPLICATION
Cutting and chamfering:
Pipe should be cut square. A simple method of cutting pipes square is to wrap newspaper or similar
sheet paper around the pipe with no overlap of the edges. Mark line around pipe (felt pen is ideal). Cut
to line with a fine toothed saw.
Pipe ends should be chamfered at an angle of approximately 15° to about
⅓
of the wall thickness with
a coarse file, surform tool or chamfering tool.
Solvent Weld Joints
Pipes up to 75mm may be jointed easily with solvent adhesives. Larger sizes require special
techniques
and require two men to make such joints.
1. Jointing Procedure. Mark depth of entry of the pipe into the socket and alignment mark.
2. Make small chamfer on the edge of the pipe end with medium file.
3. Roughen the outside of the pipe and the inside of the socket using sand paper or emery cloth up
to the entry mark.
4. Clean both surfaces and remove all dust, grease and swarf using a dry clean cloth and cleaner.
5. Stir adhesive thoroughly.
6. Apply adhesive without delay after cleaning, using a flat clean brush. Apply an even unbroken
layer brushing axially to the pipe end and socket mouth with a heavier layer on the pipe. Where
loose fits are found, the pipe should be given a second coat.
7. Immediately insert the pipe into the socket up to the entry mark, align pipe and twist 90 degrees.
Hold in position for a few seconds, then wipe off excess adhesive.
Solvent Weld jointing of large diameter pipes require special care and our Technical Service
Department should be contacted in case of difficulty. Always replace the lid of the can after making a
joint and follow the instructions on the can observing any warnings.
Joints should not be moved or disturbed for 10-15 minutes then the jointed pipe may be handled with
