PIPE/TUBE PREPARATION
1. Cutting
Plastic pipe/tube can be easily cut with a powersaw, cir-
cular saw, band saw,
or handsaw. For best
results, use a fine-
toothed blade (16-18
teeth per inch) with
little or no set (maxi-
mum 0.025 inch). A cir-
cumferential speed of
about 6,000 ft./min. is
suitable for circular saws; band saw speed should be approxi-
mately 3,000 ft./min. Carbide-tipped blades are preferable
when quantities of pipe/tube are to be cut. To insure square-
end cuts, a mitre box, hold-down, or jig should be used. Pipe
or tubing cutters can be used for smaller diameter pipe/tube
when the cutting wheel is specifically designed for plastic pipe.
2. Deburring and Beveling
All burrs, chips, filings, etc., should be removed from both the
pipe/tube I.D. and O.D. before joining. Use a knife, deburring
tool, or a half-round, coarse
file to remove all burrs. All
pipe/tube ends should be
beveled to approximately the
dimensions shown below for
ease of socketing and to minimize the chances of wiping the
solvent cement from the I.D. of the fitting as the pipe/tube is
socketed:
The beveling can be done with a coarse file or a beveling tool
such as that manufactured by Reed Manufacturing Company,
Erie, Pennsylvania.
FITTING PREPARATION
Prior to solvent welding, all fittings and couplings should be
removed from their cartons and exposed for at least one hour
to the same temperature conditions as the pipe/tube in order to
assure that they are thermally balanced before joining.
Scope
The solvent welding procedure detailed herein applies to all
NIBCO

ABS-DWV, PVC-DWV, PVC, and CPVC-CTS pressure
piping systems including molded fittings and valves. Belled-
end pipe and sewer pipe can also be joined in this man-
ner. NIBCO TECHNICAL SERVICES is available for additional
solvent-welding guidance and recommendations.
