Installation Method for Pipes and Fittings 1. **Cutting of Pipes**: Measure the required length and cut the pipe using tools such as a hacksaw, manual pipe cutter, or small circular saw. After cutting, ensure both ends are perpendicular and smooth. Remove any burrs with a file and chamfer the edges slightly, avoiding excessive chamfering. 2. **Gluing of Pipes and Fittings**: Before gluing, perform a trial assembly to determine the installation position and mark it. Lightly sand the connecting points of the pipe and fitting with sandpaper or gauze, then clean with a cotton cloth soaked in acetone. After the acetone evaporates, apply an even layer of adhesive to both the pipe and fitting using a brush, ensuring no areas are missed. Insert the pipe immediately and rotate it to the desired angle. Use a wooden mallet to tap the pipe fully into the socket. The joint will set in approximately 2–3 minutes. Do not attempt to disassemble or adjust the direction during this time, as it may cause leakage. Wipe away any excess adhesive after assembly to maintain cleanliness. 3. **Connection of Bell-End Pipes**: Clean the inner wall of the bell-end pipe and the outer wall of the straight pipe’s insertion section. Place the rubber ring into the groove of the bell-end (with the sloped side facing outward). Apply lubricant to the insertion part of the straight pipe. Align and insert the straight pipe into the bell-end. Depending on the construction site, use a puller or pry bar to insert the straight pipe up to the marked position. Mark the insertion length on the straight pipe (this length should be slightly shorter than the bell-end depth). **Other Product Information** - **Quality**: ABS and PVC-U products must have smooth inner and outer walls without burrs.
