What are the disadvantages of using iron for water pipes? Is it better to use copper for water pipes

1.Steel pipes are used for tap water.

2.The use of this type of steel pipe can lead to oxidation, giving the water a rusty color. This leads to recontamination of tap water.

3.After 30 years of use at the same time, it will rust leak and rust crack.

4.Any longer pipe may even become blocked.

5.Copper pipes are commonly used abroad. It can disinfect tap water. It is not easy to rust and not easy to block the pipe. But the cost is high. There is less domestic adoption.

Can only be used on sewer pipes. Not for use in water mains. Because PVC is toxic.

7.At present, polypropylene pipes, or ABS pipes, and aluminum-plastic pipes are commonly used as tap water pipes.

Iron water pipes are easy to be corroded and used all year round to reduce the use efficiency, such as the corrosion of heating pipes causes heat loss, causing unnecessary waste of energy, copper water pipes effectively avoid the generation of rust but the cost is too high is not conducive to universal use, PVC pipe cost is low, easy to install, conducive to disassembly, good durability in indoor but not suitable for outdoor use.

Iron is easy to rust, copper and PVC are not very good, it is better to use PPR as drinking water pipe for environmental protection, PVC as drainage pipe.

Iron will cause secondary pollution to water sources and so on.

Copper is obviously the best now, but the interface and other places need to be soldered, and it is perfect.

PVC is now the most used. It is easy to modify, cheap and durable. It should be noted that if you do concealed water pipe treatment, please be careful not to connect the water pipe buried in the wall, but to pipe it to the end.

My space, decoration class.

Iron is prone to rust, if it were the north. Sometimes it can freeze and break. PVC can also be frozen.

Copper pipes for decoration water pipes are not very good. The main reason is that the cost of copper pipes is too high, and the wall thickness of copper pipes is difficult to have pipes that really meet the wall thickness requirements of the specification, which causes some hidden dangers in the later stage.

Moreover, during the decoration, there will also be a situation in the welding of the copper pipe, that is, after the copper pipe is welded, there is no problem in the pressure test, but due to the long-term flow of water, the welding slag that has no problem at that time will be brought away and there will be water leakage. Therefore, copper pipes require high on-site construction quality and high operation level of workers, so copper pipes are not recommended for general home decoration.

Decoration of the choice of water pipes.

The most commonly used PPR water pipes for decoration water pipes. The biggest advantage of PPR pipe is that its pipe and pipe fittings are hot-melted, and the pipe and pipe fittings are connected as a whole after hot melting, and this kind of pipe is directly buried in the ground or in the wall, and the risk in the later stage is almost small. In addition to the characteristics of light weight, corrosion resistance, no scaling, and long service life of general plastic pipes, PPR pipes also have the following main characteristics:

1. Non-toxic and hygienic.

2. Thermal insulation and energy saving.

3. Good heat resistance.

4. Easy installation and reliable connection.

5. The material can be used.

1. Plastic pipes and copper pipes have their own advantages and disadvantages as water pipes, plastic pipes have more organic matter, and copper pipes have multiple metals. Brass is an alloy of copper, zinc and lead, and solder is also used, and the commonly used solder is an alloy of lead and tin. These lead and tin metals are very harmful to the human body, especially to children's intelligence.

PPR and PVC pipes release organic matter, which is a big hazard for feeding bacteria, but if the tap water is properly disinfected in the waterplant and the waterplant is not far from the tap, this is not a problem. A lot of microorganisms were detected in the test, and the important reason should be that the disinfectant can hardly survive in the hot water and decompose quickly, so the microorganisms grow wildly.

2. Although copper pipes are generally used for 50-60 years, if the local water source is not suitable, the pipes may burst in 1 year. Under normal circumstances, PVC and PP have a lifespan of 50-60 years. But PPR and PVC should not be exposed to the sun.

3. If the economic conditions permit, the local water source is not particularly corrosive to copper, lead and other metals, and copper pipes are also a good choice, but the technical requirements for installing copper pipes are not well installed, one of which is to bury hidden dangers for corrosion and burst pipes soon in the future, and the other may lead to the release of high heavy metals. Plastic pipes are cheap, easy to install, and have good safety performance, so they are also a good choice.

It is highly recommended to use copper tubes, PPR tubes will produce a large number of toxins and a large number of viruses for a long time, which is not good for the body, and copper pipes will not produce toxic substances and toxic germs after hundreds of years, and will automatically remove the virus. Now China is still using a large number of PPR pipes, is an undisclosed secret in the industry, foreign countries have eliminated PPR pipes several years ago, PPR pipes are only used for industrial purposes, foreign PPR pipes are imported into the Chinese market, poisoning the Chinese, please boycott the use of PPR water pipes in civilian use.

Copper pipe: copper pipe has the advantages of corrosion resistance, sterilization, etc., is the best product in the water pipe, the copper pipe interface has two kinds of ferrule and welding, the ferrule is the same as the aluminum-plastic pipe, there is a problem of aging and water leakage for a long time, so in Shanghai and other places. Decoration of water pipes with copper pipes is good or not to install copper pipes most of the users use welding, welding is the interface through oxygen welding together, so that it can be the same as PPR water pipes, never leakage, copper pipes one of the disadvantages is fast heat conduction, so the famous Shanghai Sanjing, Baoyang and other copper pipe manufacturers produce hot water pipes are covered with plastic and foaming agents to prevent heat dissipation, another disadvantage of copper pipes is expensive, very few community water supply systems are copper pipes, I am afraid only in export apartments and high-end villas will be seen.

If you plan to change the water pipe and think that the copper pipe is good, it is recommended to use the welded interface method. Some netizens mentioned that the Oriental Home West Sanqi store has a British IBP copper pipe, I haven't used it, you can go to investigate.

Copper pipes are good, but you have to consider the cost, and the rescue is that copper will oxidize after a long time, which is not very good for water quality.

Now they all use PPR tubes, the mainstream products in the market.

In fact, copper pipes have been used in more developed countries for a long time, foreign consulates in China also use copper pipes, and PP-R pipes are used in industry and breeding abroad. In addition, China's understanding of patina is wrong, resulting in China not using copper water pipes. Aeruga is an oxide of copper, low toxicity, insoluble in water, melting point as high as more than 200 degrees, in traditional Chinese medicine patina is used in medicine.

The production of patina is also very harsh, requiring air, humidity and a certain amount of sunlight, so the copper pipe is not well connected on the outside and will produce patina, and there will be no patina inside to pollute the water quality. In addition to being the most expensive, copper pipes are better than PP-R pipes. In addition, in July and August 2017, the state stipulated the materials of community water supply pipes, but it was not enforced.

1. PPR tube. The new type of water pipe material, which can be used as both cold pipe and hot water pipe, has the characteristics of non-toxic, light weight, pressure resistance, corrosion resistance and so on. It will not exist for a long time like the aluminum-plastic pipe, and the PPR pipe will not scale.

The main defects of PPR water pipe are: high temperature resistance, slightly worse pressure resistance, and long-term working temperature can not exceed 70; The length of each section is limited, and the construction can not be bent, if the pipeline laying distance is long or there are many corners, a large number of joints will be used in the construction; The tubing is cheap but the fittings** are relatively high. 2. Copper pipe.

It has the advantages of corrosion resistance and sterilization, and is the best product in the water pipe, and there are two ways of copper pipe interface: ferrule and welding. The ferrule has the problem of aging and leakage for a long time, so most of the users who install the copper pipe adopt the welding type, and the welding is that the interface is welded together by oxygen, so that it can be the same as the PP-R water pipe, and never leak. One of the disadvantages of copper pipes is that they conduct heat quickly, so the hot water pipes produced by famous copper pipe manufacturers are covered with plastic and foaming agents to prevent heat dissipation.

If it is a water pipe, it is recommended that the copper pipe is safe, hygienic and durable;

If it is a sewer pipe, it is recommended to pvc pipe, which is cheaper.

Of course, if you have money, it's good to install copper pipes, it's too expensive.
