PPR water pipes are a breeding ground for bacteria to multiply! What is the basis for this?

As a new type of water pipe material, PPR pipe has a unique advantage, it can be used as a cold water pipe, can also be used as a hot water pipe, because of its non-toxic, light weight, pressure resistance, corrosion resistance, is becoming a kind of promotion of the material, the current decoration project is still relatively small, PPR pipe is not only suitable for cold water pipeline, but also suitable for hot water pipeline, and even pure drinking water pipeline. The interface of the PPR pipe adopts hot melt technology, and the pipes are completely integrated together, so once the installation pressure test is passed, it will not exist for a long time like the aluminum-plastic pipe, and the PPR pipe will not scale, and some high-end residential and apartment units generally use PPR water pipe as a cold water pipe and hot water pipe, PPR pipe is known as never scaling, never rusting, never leaking, green advanced water supply material.

Characteristics of PPR tubes:

1. As a new type of water pipe material, PPR pipe is hygienic, non-toxic, non-rusty, non-scaling, and meets the international standard of drinking water.

2. High temperature resistance, high pressure resistance, heat preservation and energy saving. Low resistance, fast water flow and low noise.

3. Light weight, good toughness, impact resistance, the specific gravity is only one-eighth of that of metal pipes, and the pressure test strength is more than 50kg cm2. Easy to install, reliable to connect and never leak. The service life can be as long as 50 years under normal conditions.

If your water pipe does have a big plastic smell, there are two reasons, 1 is that the PPR pipe is a counterfeit product, 2 is that there is a problem with the pipe fittings of your water inlet pipe, you can find out whether the neighbor also has such a problem, if there is, it is the problem of the total water inlet pipe, if not, it is your problem, you can find the person who installed the water pipe for you to change, otherwise you can go to the consumer association to complain about him!

The main reason is that bacteria form a biofilm, and the adhesion ability and anti-interference ability of bacteria are greatly enhanced after the formation of biofilm.

PPR water pipes have become health killers, and experts have revealed the inside story of the industry.

After the PPR plastic water pipe is used for a period of time, the inner wall of the pipe is seriously polluted, which is the breeding ground for bacteria and legionella, and has become a new human health killer and a potential threat to life, so it is not suitable for household water pipes.

In 2002, when PPR plastic pipes began to be used as tap pipes in Chinese households, an unpublished test report from the Beijing Municipal Center for Disease Control and Prevention showed that the total number of bacteria flowing out of household PPR water pipes was countless, and Legionella pneumophila types 1 and 5 were detected, which was an alarming number of more than the galvanized pipes that had been banned. The results of the water quality test (not published) by the relevant departments are:

There are as many as 28 kinds of bacteria and 16 kinds of metal elements, among which iron, manganese, zinc, lead and mercury exceed the standard seriously. (See annex report).

PPR water pipes are a breeding ground for bacteria to multiply. The pipeline industry has sampled the dirt on the inner wall of the PPR water pipe after a period of use, and the test results are: a yellow rust tumor, containing microorganisms such as bacilli, coccus, and fine bacteria, a large number of iron bacteria, Ehir coli, intestinal bacteria, habitat bacteria, Acinetobacter, Aeromonas, Arthrobacter, Bacillus and at least 14 biotypes of Pseudomonas puta, and even found the breeding of chlorine-resistant microorganisms such as Anthobacterium, Brittle Bacillus, Litubular Snail and Chlorella.

The concentration of heterotrophic bacteria, E. coli, radiobacteria and fungi in the dirt on the inner wall of the tube is extremely high. Tongji University, Tsinghua University, Shanghai Water Purification Association, International Copper Association (China), Wuhan Institute of Virology, Chinese Academy of Sciences, etc. have all discussed it.

The PPR plastic pipe itself is non-toxic and hygienic, but the PPR plastic pipe has no self.

Copper water pipe: corrosion resistance, sterilization and other advantages. Most of the copper pipes are welded, and the welding is that the interface is welded together by oxygen, and crimping is the latest installation technology.

PPR pipes: not only for cold water pipes, but also for hot water pipes, and even pure drinking water pipes. The interface of the PPR pipe adopts hot melt technology, and all the pipes are completely integrated together, which is a green high-grade water supply material.

A lot of people have been talking about toxicity lately.
