1. Light weight, convenient handling: small density, convenient handling, loading and construction.
2. Excellent corrosion resistance: It has excellent acid resistance, alkali resistance and corrosion resistance, and is very suitable for use in the chemical industry.
3. Low fluid resistance: the inner wall of the pipe is smooth, its roughness coefficient is only 0.009, and the fluid resistance is small, which effectively improves the hydraulic conditions of the pipe network and reduces the system operating costs.
4. High mechanical strength: the pipe has good pressure resistance, impact resistance and tensile strength.
5. Simple construction: the pipeline connection construction is fast and easy, and the construction cost is low.
6. Low cost: low price, convenient transportation and construction, long service life, so the overall cost is low.
7. No impact on water quality: It is confirmed by the dissolution test that it does not affect the water quality and is suitable for large-scale promotion and application.
1. It has good tensile and compressive strength
2. The wall of PVC pipe is very smooth and has little resistance to fluid
3. Excellent corrosion resistance: It has excellent acid resistance, alkali resistance and corrosion resistance, and is very suitable for use in the chemical industry.Low fluid resistance: the inner wall of the pipe is smooth, its roughness coefficient is only 0.009, and the fluid resistance is small, which effectively improves the hydraulic conditions of the pipe network and reduces the system operating costs.
4. The installation of PVC pipes, whether connected by bonding or rubber ring, has good water tightness.
5. PVC pipe is not a nutrient source, so it will not be eroded by rodents.
6. Performance test: curing time, shrinkage, splitting strength, tensile strength, peel strength, thermal stability, shelf life, release of harmful substances.bility, and can be used in different environments.
1. The proportion of the material is only 1/10 of that of cast iron, which is easy to transport and install and reduces the cost.
2. Excellent chemical resistance, excellent acid and alkali resistance
3. Non conductive: The material cannot conduct electricity and is not corroded by electrolysis and current.
4. It can neither burn nor support combustion, and has no fire protection concerns.
5. Easy installation and low cost. It is easy to cut and connect. PVC glue is used for connection, which is reliable and safe
6. It has good weather resistance and can not be corrupted by bacteria and fungi.
7. The inner wall is smooth, the fluid fluidity loss is small, the dirt is not easy to attach to the smooth pipe wall, the maintenance is relatively simple, and the cost is low.
The thermal conductivity and elastic modulus are small, and the frost resistance is better than that of cast iron drain pipes. The pipes and pipe fittings can be connected by bonding. The construction method is simple, the operation is convenient, and the installation efficiency is high. The pipeline has excellent corrosion resistance to inorganic acid, alkali and salt, and is suitable for industrial sewage discharge and transmission. The friction coefficient of the pipeline is small, the water flow is smooth, it is not easy to block, and the maintenance workload is small. The material has high oxygen index and self extinguishing property. The linear expansion coefficient of the pipeline is small, 0.07mm/℃, and the deformation affected by temperature is small.
