PVC pipe mainly includes PVC drainage pipe, PVC water pipe, PVC conduit pipe, etc. Of course, new materials such as PVC-M pipe, PVC-O pipe, we use the basic PVC drainage pipe and PVC water pipe, then these two pipes in the use and advantages of what specific differences, the following describes the analysis.
PVC plumbing pipe is used for water supply, is used to drinking water pipes, relative to the requirements of the drainage pipe to be higher. In addition to physical requirements to meet the requirements, such as Material generally require PVC new material, and requiring environmentally friendly, It is essential that Will not be stored in the tube of water release harmful substances. PVC water supply pipes are also used for farmland irrigation, the biggest difference with the drain is the need to withstand the pressure, If the water supply project need to have health indicators, non-toxic pollution-free test indicators.
PVC water pipe advantages:
1. Light weight, handling hand ling convenience: the density is small, handling, handling, construction convenience.
2. Excellent corrosion resistance: excellent acid resistance, alkali resistance, corrosion resistance, for the chemical industry is very suitable for use.
3. The fluid resistance is small: the inner wall of the pipe is smooth, the roughness coefficient is only 0.009, the fluid resistance is small, which effectively improves the hydraulic condition of the pipe network and reduces the running cost of the system.
4. Mechanical strength: pipe has a good pressure resistance, impact resistance and tensile strength properties.
5. Construction is simple: the pipeline is easy to connect the construction, construction costs low.
6. Low cost: low price, and transport, construction convenience, long life, so the overall low cost.
7. Does not affect the water quality: confirmed by the dissolution test does not affect the water quality, suitable for large-scale promotion and application.
PVC drainage pipe is used for drainage, mainly for real estate projects on the drainage, rain, residential drainage, the pipe itself is not the pressure and health indicators, the difference between the quality of the main pipe depends on toughness, stretching and so on.
Advantages of PVC drain pipe:
1. Pipe surface hardness and tensile strength is excellent, high safety pipe.
2. Good anti-aging, the normal life of up to 50 years.
3. Pipeline on the inorganic acid, alkali, salt corrosion resistance, suitable for industrial wastewater discharge and transportation.
4. Pipeline friction coefficient is small, smooth flow, not easy to plug, less maintenance work.
5. Material oxygen index is high, with self-extinguishing.
6. Pipeline linear expansion coefficient is small, 0.07mm / ℃, affected by the temperature deformation is small. Thermal conductivity and elastic modulus is small, compared with cast iron drainage anti-freeze performance.
7. Pipe, pipe fittings can be used to connect, the construction method is simple, easy to operate, the installation of high efficiency.
Comprehensive above, PVC water pipe and PVC drainage pipe to withstand different pressures, quality requirements are not the same, the water supply pressure, wall thickness, drainage without pressure, wall thickness, other technical indicators are low.
