PVC drainage pipe

Connection and installation of PVC drainage pipes

There are three main connection methods for PVC drainage pipes: sealing gasket, bonding, and flange connection
1. PVC drainage pipes with a diameter greater than or equal to 100 millimeters generally use rubber ring interfaces;
2. For PVC drainage pipes with a diameter less than 100 millimeters, adhesive joints are generally used, while some use flexible joints;
When PVC drainage pipes cross sewers or other pipelines, metal pipes are generally used, and plastic pipes are connected to metal pipes with flanges The connection between the valve and the pipeline is also made by flange connection
Precautions for PVC drainage pipe installation
The length of PVC drainage pipes is determined layer by layer based on actual measurements and the dimensions of each connecting pipe fitting
2. PVC drainage pipe sawing tools should use fine toothed saws, cutting knives, and pipe cutting machines The fracture surface should be flat and there should be no deformation at the fracture surface
3. The socket part of the PVC drainage pipe to be bonded can be filed into a 15-30 degree groove with a medium size board file The groove length is generally not less than 3mm, and the groove thickness should be 1/3~1/2 of the pipe wall thickness. After the groove is completed, the debris should be cleaned up
After connecting the socket interface of the PVC drainage pipe, the extruded adhesive should be wiped clean with cotton yarn or a dry cloth dipped in a small amount of acetone or other cleaning agent According to the properties of the adhesive and climatic conditions, let it rest until the interface is cured

5. The curing time of PVC drainage pipes should be appropriately extended during winter construction

Advantages of PVC ○ pipe fittings
1. Strong corrosion resistance, not affected by corrosive soil and various drinking water;
2. Smooth inner wall, with lower frictional resistance than conventional materials;
3. Pipelines and fittings will never rust, so there will be no erosion or shrinkage changes inside;
4. The exterior walls of buildings will never be contaminated by rusting pipes, ensuring that the value of the building is not compromised;
5. There are various styles and completeness of pipeline fittings, which can meet various design and installation requirements;
6. Easy to install, no need for regular maintenance and repair;
7. One fifth the weight of cast iron pipes, easy to transport and operate;
8. Using adhesive bonding, simple, fast, economical and efficient;
9. Odorless and non-toxic;
10. Can withstand a wide range of chemicals, including strong acids and bases;
11. Not susceptible to bacterial invasion;
12. Anti termite and weather resistant;
13. Cheaper than conventional materials;
14Under normal usage conditions, the lifespan can reach over 50 years.
