1、 What is PVC-U pipe
UPVC, also known as rigid PVC, is an amorphous thermoplastic made of vinyl chloride monomer through polymerization resin It is composed of certain additives (such as stabilizer, lubricant, filler, etc.). In addition to using additives, it also uses the method of blending with other resins, which makes it have obvious practical value. These resins include CPVC, PE, ABS, EVA, MBS, etc. The melt viscosity of UPVC is high and its fluidity is poor. Even if the injection pressure and melt temperature are increased, the fluidity changes little. In addition, the molding temperature of the resin is very close to the thermal decomposition temperature, and the temperature range for molding is very narrow, which makes it difficult to mold.
2、 Characteristics of PVC-U pipe
1. Light weight, convenient handling:
PVC Pipe The material is very light, easy to transport and construct, which can save labor.
2. Good chemical resistance
PVC pipe has friendly acid resistance, alkali resistance and corrosion resistance, which is very suitable for chemical industry.
3. Low fluid resistance
The wall of PVC pipe is smooth, and its resistance to fluid is small. Its roughness coefficient is only 0.009, which is lower than other pipes. Under the same flow rate, the pipe diameter can be reduced.
PVC pipe has good water pressure resistance strength, external pressure resistance strength, impact resistance strength, etc. It is suitable for piping engineering under various conditions.
5. Good electrical insulation
PVC pipe has superior electrical insulation and is suitable for wire 、 Cable Conduit of, and wiring piping on the building.
6. No impact on water quality
PVC pipe is proved not to affect the water quality by the dissolution test, and it is the * * best pipe for tap water piping at present
7. Simple construction
The joint construction of PVC pipes is fast and easy, so the construction cost is low
