Introduction to the material characteristics of plastic valve pipe (PVC)

Plastic Valve PVC (polyvinyl chloride) material is the third kind of plastic used in production after polyethylene and polypropylene. Plastic valve without any plasticizer of pure PVC is a white, brittle solid. Plastic valve PVC is widely used as building materials. Compared with traditional materials such as copper or ductile iron, plastic valve is more convenient to install and cheaper. By adding plasticizers, it can also be made into softer, lighter materials, the most widely used is phthalate. Therefore, it is commonly used in fluid transportation, power cable insulation and many applications. Pipes and fittings are polymers of poly (vinyl chloride) (PVC) class I grade I 12454 conforming to ASTM d1784. The maximum working temperature of PVC plastic valve under relative pressure is 55 ℃, and it can boil instantly (100 ℃).

Advantages of PVC plastic valve pipe:

1. Corrosion resistance: PVC plastic valve acid and alkali resistance than general cast iron pipe, galvanized pipe strong, will not rust scaling.

2. Small fluid resistance: the inner wall of plastic valve pipe is smooth without scale.

3. High mechanical strength: the plastic valve has good water pressure resistance, impact resistance and tensile strength, and can withstand 110 atmospheric pressure for 1 hour at room temperature without cracking.

4. Health non-toxic: Huanqi plastic valve unique green lead-free formula, will not damage the water quality affect human health.

5. Easy to install: the density of plastic valve is small, the weight is light, it is convenient for loading, unloading and transportation, and the installation is simple and fast.

6. Temperature performance: plastic valve UPVC water supply pipe is the best in the temperature range of room temperature.

Good water tightness: 15 minutes after the interface adhesive bonding, the bonding strength can reach more than 12.5/c.
