PE water supply pipe fittings corrosion resistance characteristics in detail

PE water supply pipe fittings have excellent corrosion resistance, good hygiene performance and long service life.

PE water supply pipe fittings for non-inert materials, in addition to a small number of strong oxidants, can be resistant to a variety of chemicals, and not easy to breed bacteria. As we all know, steel pipe, cast iron pipe is replaced by plastic pipe is not only because of plastic pipe than its low water energy consumption, low energy consumption, light weight, low resistance to water flow, easy and rapid installation, low cost, long life, with heat preservation, etc., but also because of the corrosion-resistant plastic pipe, not easy to breed microorganisms and other properties better than steel pipe and cast iron pipe.

The service life of PE pipe is more than 50 years, which has not only been confirmed by international standards and some advanced foreign standards, but also has been proved by practice.

Another reason why PE pipe can be widely used is because PVC is increasingly subjected to the pressure of environmental protection. Firstly, the hygienic properties of PVC itself: it is well known that the production of PVC pipes under regular production and strict control can guarantee the hygienic properties and allow the application in the field of drinking water. However, there are concerns that problems may occur where controls are not tight: for example, excessive levels of vinyl chloride monomer (VCM) in PVC resins, and the misuse of toxic additives in the formulation of PVC pipes for water supply. Misuse of PVC pipes and fittings for drainage, which are not guaranteed to be non-toxic, for water supply pipes and fittings, etc. Secondly, it is the recycling problem of PE pipe: PVC and polyethylene are thermoplastic plastics, theoretically speaking, they can be used, but countries have proved that the proportion of old plastic products that can be recycled is limited, and the main way of treatment is to incinerate and recycle the energy, PVC because it contains chlorine, and it may produce harmful substances when it is incinerated under bad control, while polyethylene only contains hydrocarbon and water and carbon dioxide are generated after incineration.
