What is UPVC?
UPVC or Unplasticized PVC,PVCU is composed of certain additives (such as stabilizers, lubricants, fillers ) and amorphous thermoplastic resin which vinyl choride monmer is polymerzated to made .In addition to using the additive,using approach of blending with other resins modified has obvoius practical value.These resins have CPVC, PE, ABS, EVA, MBS etc. High melt viscosity of UPVC,poor mobility,even with a high injection pressure and melt temperature,liquidity will not change much.Molding temperature and thermal decomposition temperature is very close.so molded temperature range is very narrow and UPVC is a difficult molding material.
Why Choose UPVC Pipe for Water Supply?
UPVC pipe is non-toxic,no pollution and corrossion-resistant.application pplication temperature is not more than 40 degrees (cold water pipe).diameter of pipe is 40-100mm .the common application engineering of UPVC pipe iswaterworks ,electrical ,construction ,ground water ,telephone,well drlling,salt water ,gas supply ,chenmical factory,paper mill,acidifying&fermenting plant,electroplating groend,,agricultual plant,,mining plant,free way,,golf course engineering,fishery use for plastic raft.
What are advantages of UPVC Pipe for Water Supply?
1. light weight, convenient transportation and handling:
2.PVC pipe has excellent resistance to acid, alkali, corrosion resistance, very appropriate for the chemical industry
3.Small fluid resistance:
Smooth pipe wall , small fluid resistance , the roughness coefficient only 0.009, lower than other pipe;at the rate of same flow, the diameter can be reduced.
4.mechanical strength
Better Water pressure resistance strength , pressure-resistant strength andimpact strengthvery appropriate for a variety of conditions of the plumbing.
5.good electrical insulation properties
PVC pipe has excellent electrical insulation for wire /cable conduits and wire pipe for building.
6.does not affect the water quality
PVC pipe does not affect water quality because of confirmation of the dissolution tests ;the best pipe for drinking water pipe
7.simple construction
joining of PVC pipe construct quicklyand easily, so the construction project costs low.
