PVC drainage pipes can be connected by adhesive.

1. First, cut the PVC drainage pipe according to the size with a fine-tooth saw and a cutting knife. Use a plate hammer to remove burrs and burrs from the fracture and chamfer them. Wipe the dust, water and oil stain on the surface of the socket with a dry cloth.

2. Apply the adhesive evenly to the socket. Quickly insert the socket into the socket and turn it to a quarter turn for at least 1 minutes to allow the adhesive to cure.

3. Wipe off the excess adhesive outside with a cloth, and water can be supplied 2 hours after connection.

1. Advantages of pvc water pipes

Good tensile and compressive strength.

low fluid resistance: the wall of PVC water pipe is very smooth, with low resistance to fluid, and its roughness coefficient is only .9. Its water delivery capacity can be improved by 2% compared with that of cast iron pipe with the same diameter and 4% compared with that of concrete pipe.

excellent corrosion resistance and drug resistance: PVC water pipes have excellent acid resistance, alkali resistance and corrosion resistance, and are not affected by wet moisture and soil pH, and no anti-corrosion treatment is needed when laying pipes.

good watertightness: the installation of PVC water pipes has good watertightness, regardless of adhesive or rubber ring connection.

anti-biting: PVC water pipe is not a nutrient source, so it will not be eroded by rodents. According to national sanitation foundation's experiment in Michigan, rats won't bite PVC pipes.

second, the disadvantages of pvc water pipes

Pvc water pipes are not as flexible as other plastic pipes.

the thermal stability and impact resistance are relatively poor, and both rigid and soft PVC are prone to brittleness during use. It will do harm to the human body.
