PVC drainage pipe is the largest amount of plastic pipe in the water supply and drainage project. The setting of the drainage pipe generally depends on the slope of the pipeline to achieve the flow effect. Because the inner wall of the PVC drainage pipe is very smooth, its roughness coefficient is 0.009 (0.015 for cast iron). Therefore, under the same inner diameter, the flow of the PVC drainage pipe is much larger than that of the metal pipe, and the scale will not adhere to the pipe for a long time. Therefore, the flow does not always have a low level of change, and the excellent acid and alkali resistance and corrosion resistance characteristics of the PVC drainage pipe are added. This is one of the most practical pipes for the sewer line. Next Xiaobian introduced PVC drainage pipe specifications and PVC drainage pipe features.
PVC drainage pipe specifications
The commonly used pvc drainage pipe specifications are mainly based on the nominal outside diameter, respectively 32mm, 40mm, 50mm, 75mm, 90mm, 110mm, 125mm, 160mm, 200mm, 250mm, 315mm, 400mm, 500mm, most pvc drainage pipe specifications have A certain gap, this is normal. The length of PVC-U pipe is generally 4m or 6m, and other lengths are determined after consultation between the supply and demand sides.
PVC drainage pipe features
1, strong corrosion resistance, free from corrosive soil and various drinking water;
2. The inner wall is smooth and has less frictional resistance than conventional materials;
3. Pipes and fittings will never rust, so there will be no change in erosion and shrinkage inside;
4. The external walls of the building will never be contaminated due to rusting of the pipeline, so as to ensure that the value of the building will not be damaged;
5, pipe fittings styles, complete, can be suitable for a variety of design and installation requirements;
6, easy to install, without regular maintenance;
7, one-fifth the weight of cast iron pipe, easy to transport and operate;
8, using glue bonding, simple and quick, cost-effective;
9, odorless, odorless, non-toxic;
10, can withstand a wide range of chemicals, including strong acid and alkali;
11, from the bacteria;
12, anti-termite, weather-resistant;
13, cheaper than conventional materials;
14, life under normal use conditions up to 50 years.
