It provides stronger and tighter <br /> joints than threading. Here are tips that should be useful. <br /> 1. Use the proper solvent cement: PVC cement with PVC pipe,and PVDC cement with PVDC pipe. <br /> 2. When solvent welding PVC pipe,apply PVC cement liberally to the pipe O.D.and to the fitting I.D. <br /> 3. Leave a fillet bead between pipe and fitting when solvent welding PVC and PVDC piping,but remove excess cement <br /> from ABS and CAB. <br /> 4. Use a natural (hog) bristle brush for applying solvent cement; nylon and other synthetic materials are attacked by <br /> solvents in the cements. <br /> 5. Use a%z"wide brush for pipe%"through 1";a 1"brush for 1'/4"through 2"pipe;and a 2"brush for pipe 3"and larger. <br /> 6. An ordinary oil can is an excellent container for acetone or cleaner. Excessive evaporation is prevented and the solvent <br /> is always handy. <br /> 7. Never allow water to come into contact with solvent cement. Wrap a handkerchief around your forehead in hot weather <br /> to keep perspiration from dripping into the cement. When not using cement keep it covered. <br /> 8. Allow solvent cement to cure 5 to 15 minutes before handling and wait 24 hours before introducing full line pressure in <br /> a solvent-cemented piping system. <br /> 9. At end of the day,place the brush in the solvent and cover the cement tightly. When re-using the brush,shake excess <br /> solvent out before dipping it into the cement. <br /> SOLVENT CEMENT REQUIREMENTS <br /> NOMINAL AVG.NUMBER OF NOMINAL AVG.NUMBER OF <br /> SIZE OF PIPE JOINTS PER QT.
