The difference of PVC plastic pipe and PE pipe?
The same plastic pipe, the difference lies in the two properties and advantages are not the same, PVC plastic pipe is the main advantage of flame retardant, wide use, PE pipe can only be used in ordinary civil pipe.
Light weight, good toughness, good low temperature resistance, non-toxic, low cost, high impact strength, compressive strength and tensile strength but lower thermal welding, flange connecting thread water pipe, rain water pipe, gas pipe, industrial pipe corrosion
PVC has good tensile and compressive strength, but its flexibility is better than other plastic pipe, excellent corrosion resistance, the cheapest price in all kinds of plastic pipe, but low temperature brittle adhesive, rubber ring socket flange connection, threaded connection for residential living, industry, agriculture, irrigation, water supply and drainage, exhaust gas pipe, wire pipe, rain water pipe, industrial anti-corrosion pipe etc..
HDPE pipe must bear a certain pressure, usually choose a large molecular weight and good mechanical properties of PE resin, such as HDPE resin. LDPE resin has low tensile strength, poor pressure resistance, poor rigidity, poor dimensional stability during forming and difficult connection. It is not suitable to be used as material for feed water pressure pipe. But because of its high hygienic index, LDPE, especially LLDPE resin, has become a common material for producing drinking water pipes. The viscosity of LDPE and LLDPE resin is small, the flowability is good and the processing is easy, so the range of their melt index is wide, and the MI is usually between 0.3-3g/10min.PVC pipe is a kind of plastic pipe with PVC (PVC) resin as raw material and without plasticizer. With the development of chemical industry technology, we can produce non-toxic materials, so it has the general properties of PVC, added some excellent properties, specifically it has corrosion resistance and good flexibility advantages, which is especially suitable for water supply network. Because it does not conduct electricity, it is not easy to react with acid. Alkali. Salt undergoes an electrochemical reaction, so acid. Alkali. It is difficult for salt to corrode it, so there is no need for an anticorrosive coating and lining. And good flexibility, which overcomes the brittleness of plastic pipes in the past, can produce yield under load without rupture
