PVC pipe is made of polyvinyl chloride resin and stabilizer, lubricants with hot pressing extrusion molding plastic pipe material, generally used for drainage, waste water, chemicals, heating liquid and coolant transportation, food, ultra-pure liquid, mud, gas, compressed air and vacuum system transmission.
PVC can be divided into soft PVC and hard PVC. Soft PVC is generally used for floor, ceiling and leather surface, but due to the poor physical properties of plasticizer contained in soft PVC, the scope of use is limited. Hard PVC does not contain plasticizer, so it is easy to form and has good physical properties. PVC material production process, to add stabilizer, plasticizer and so on, if all the use of environmental additives, the PVC pipe is also non-toxic and odorless environmental products.
The advantages of PVC pipe
1 It has good tensile strength and compressive strength, but its flexibility is not as good as other plastic pipes.
2 fluid resistance is small: PVC-U pipe wall is very smooth, the resistance to fluid is very small, its roughness coefficient is only 0.009, its water delivery capacity can be compared with the same diameter of cast iron pipe 20%, 40% more than the concrete pipe.
3 corrosion resistance, drug resistance is good: PVC-U pipe has excellent acid resistance, alkali resistance, corrosion resistance, not affected by moisture and soil pH, pipeline laying without any anti-corrosion treatment.
4 with good water tightness: PVC-U pipe installation, whether the use of adhesive or rubber ring connection, have good water tightness.
5 bite prevention: PVC-U tube is not a source of nutrition, will not be eroded by rodents.
