The advantages of PVC-U pipe.
1.Light weight, convenient to carrying and loading
With the light weight, the specific gravity of PVC is just one-fifth of the iron pipe. So it is convenient to carrying, loading and operating and can save the cost.
2.Good corrosion resistance and chemical-proof
With excellent acid-resisting, alkali-resisting and corrosion resistance, PVC can be used widely in the fields of chemical industry and waste water.
3.Small liquid resistance
With smooth flow of the inner wall and small liquid resistance, the coefficient of roughness is just 0.009, which is lower than that of other pipes. With the same caliber, it can hold more flow volume and no adhesion of incrustation scale.
4.Large mechanical strength
Having good strength of resisting water pressure and impact, at ordinary temperature, it can be used to any conditions of piping engineering.
5.Excellent electrical insulation
PVC pipe has excellent electrical insulation so it can be used as wire, cable casing pipe and can be widely used in telecommunications, power piping and wire piping on the construction.
6.No impact on water quality
The result of the dissolution test proves that PVC pipe does not affect the quality of water, being the best choice for tap-water pipe.
Its connections, both the loopier socket and the socket joint have the good water-tightness.
PVC pipe can be constructed quickly and easily with low cost.
9 .Long life-spans
Under the normal working pressure, it can be used for more than 50 years.
10 ..Low cost
With low cost in transporting, installing and material, the whole project can save 30%-40% cost than that of iron pipe.
How to operate PVC glue/adhesive
Compared with the pipe and traditional pipes of PVC, its highlights depends on the situation where its internal cavity is not easy to have dirt, which ensures the flow of the medium in the pipe. In addition Essence
In order to ensure that the construction of the PVC -to -water pipe's project can be relatively standardized. When carrying out a bonding connection, it is necessary to ensure that the pipeline is sufficient in the pipeline. In addition, pay attention to the demand of the glue agent, and strive to be appropriate. If the amount of use is not enough, you cannot obtain sufficient glue.
However, the amount of adhesive agent in the water pipe is used too much. In addition to the slow evaporation of the solvent, and then the actual effect is slow, the glue agent in the pipe will be slightly harmful to the water flow. The decrease in pressure to withstand is also very easy to cause pipes to crack.
When punching the PVC water pipe, pay attention to the punching diameter of less than 50mm, the PVC drainage pipe drilling equipment can be poured; when the perforated diameter exceeds 50mm, a circular cutter can be used, or the pipe can be selected. Burning red hot holes. In addition, in the process of taking over, to ensure that PVC's normal application of water pipes does not have to be seepage due to carelessness and the problem of soil pollution of sewage to soil pollution.
However, the PVC water pipe is a plastic product. Its rigidity is far less rigid than the cast iron pipe, and its expansion coefficient is large, so it is necessary to effectively select support. And in the case of selecting its products, we must make more comparisons, strictly control the quality, bypass various artificial mistakes, and avoid unqualified products from entering the construction site.
