Which is more corrosion resistant, plastic material or metal material?

Hello: The water pipes in the bathroom at home use plastic materials with better corrosion resistance, because plastic materials are less likely to be corroded, while metal materials will rust after a long time of use, and slowly corroded!

Therefore, the water pipe in the bathroom at home uses plastic materials for better corrosion resistance! Hope it helps, hope, thank you!

It is recommended to use metal materials for water pipes in the bathroom at home, because metal materials are strong and durable, and household water pipes are corrosion-resistant metal and non-metal.

It's still plastic, because plastic is more corrosion-resistant, and the effect is relatively good.

It is better to use plastic for toilet water pipes, because for sewage, plastic is more corrosion-resistant than metal and has a longer service life.

It is best to use plastic pipes in the bathroom at home, which is cost-effective and more corrosion-resistant than metal materials, which is why plastic sewer pipes are commonly used in commercial housing.

The water pipes in the bathroom at home should be made of plastic materials, and the corrosion resistance is better, because metal materials are easy to corrode. How many years will it corrode. There is a leak. Not easy to repair.

From the perspective of corrosion resistance, it must be that the metal material will be better. Plastic pipes are more economical.

Compared with the water pipes in the bathroom at home, compared with the plastic material and the metal material, I personally think that the corrosion resistance of the plastic material is better.

I think the water pipes used in the bathroom at home are still plastic, which is better than metal corrosion resistance. Now the plastic ones, especially those neon products, are still relatively reliable, and they are not afraid of some corrosive things, while the metal ones, whether they are stainless steel or carbon steel, cannot withstand corrosion. It needs to be replaced every time in a short time, and the plastic material is very durable and resistant to corrosion.

Of course, plastic water pipes are more corrosion-resistant, but if they are metal pipes, then they are easy to corrode, because they have undergone oxidation and are often in contact with water. The corrosion is faster, and the plastic can resist corrosion.

Plastics are less prone to rust and are resistant to corrosion, while metal does not have these advantages. Moreover, compared with plastic, it is more beautiful and easy to install and maintain, and there are many advantages of plastic in comparison.

The water pipes in the bathroom at home must be made of plastic, which is more resistant to corrosion than metal materials. Metal pipes will rust after a while. If the water pipe is not used for a while, it will also rust inside, and it will have to be replaced every ten years.

Of course, the bathroom water pipes at home are plastic, which is more corrosion-resistant. Because the density of plastic is relatively large, it is more resistant to corrosion and acid and alkali.

In fact, if you want to talk about materials, metal materials and plastic materials, in fact, I think metal materials are more comfortable to use, but metal materials will actually corrode, because after all, after the metal is stained with water, these will rust, and after more than ten years, they need to be replaced, and some may need to be replaced in a few years, but metal materials are really strong, so I think it is better to use plastic materials for bathroom hoses at home, the sound is light, and the second is that it is easier to install and maintain.

For the water pipes in the bathroom at home, I think the corrosion resistance of plastic materials is a little better than that of metal materials.

This is mainly due to the fact that the bathroom is generally humid and will rust after using metal materials for a long time. Plastic materials can avoid this defect.

Metals are more susceptible to corrosion, while plastics have better corrosion resistance.

Plastic is better, because the material made of metal is easy to rust and corrode in a humid environment.

For the decoration of the bathroom at home, it is better to use PVC plastic water pipes, and metal water pipes still do not have PVC pipe corrosion resistance.

Plastic pipes are better than metal materials, so that the plastic will not be corroded after a long time, and the metal equipment will rust after a long time, and the rust will corrode the metal water pipe.

The plastic ones are better, and the metal ones are easy to rust.

The water pipes made of plastic materials used in the bathroom must be more resistant to corrosion than metal, because the metal is particularly easy to rust, and the plastic material should be said to be very good in this piece.

Stainless steel or copper are particularly durable, much better than plastic.

I think that for bathroom water pipes, edible plastic materials should be better, because metal materials are more likely to be corroded when using water for a long time to supply pipes, while plastic has a longer lifespan.

The water pipes in the bathroom at home should be made of plastic materials. Compare corrosion resistance if metal materials are used. Not durable.

If we talk about corrosiveness alone, plastic ones are more corrosion-resistant, but plastic ones also have a service life.

It is best to use plastic for the water pipe in the bathroom at home, because plastic corrodes slowly and is not easy to break, and metal sewer pipes are easy to break, so I recommend that you try to use plastic sewer pipes.

The corrosion resistance is better than that of plastic pipes, so that plastics will not be corroded after a long time, and metal equipment will rust after a long time, and rust will corrode metal water pipes.

Of course, it is better to use plastic materials, which are not easy to rust and are more durable. The metal material is too rusty and corroded.

There are several materials for household water pipes: PP-R pipes, aluminum-plastic pipes, copper pipes, PB pipes, and PVC.

1. PP-R pipe

This is a new type of water pipe material, whether it is a cold water pipe material or a hot water pipe material, it is competent. It has non-toxicity, light texture, corrosion resistance, not easy to age, and will not appear scaling; However, the high temperature resistance and pressure resistance are not too good, and the length of each section is limited, so it cannot be tortuously constructed.

2. Aluminum-plastic pipe

Aluminum-plastic pipe is a new type of pipe made of co-extrusion and compounding. At present, it is a kind of pipe that is more popular in the market. The texture is light, durable and easy to construct, and the bending nature of the aluminum-plastic pipe is completely no problem in home decoration.

The inner and outer layers of the aluminum-plastic pipe are made of special polyethylene material, which is non-toxic for cleaning. It has outstanding resistance to high and low temperatures, and has a long service life. However, when it is used as a hot water pipe, the long-term change of heat and cold will cause the pipe wall to be misaligned, which can lead to leakage.

3. Copper pipe

Copper pipe has the advantages of corrosion resistance and sterilization, and is the top grade in water pipe materials. **Expensive, using card sleeves is prone to water leakage.

4. PB tube

PB pipe is recognized as a non-toxic, odorless, durable pipe material that can be recycled, with low energy consumption, high surface finish and high flexibility throughout the life cycle. However, the PB pipe is relatively soft, and in the case of high temperature, it is easy to have cracks in the collision and impact, and the construction requirements are very high, so protective measures must be taken.

5、pvc

With the advancement and development of science and technology, there is a household water pipe made of PVC, which is a polymer material. At present, most of the water pipes in the market are made of this material, because of the low cost, so the range of use is also relatively wide. However, the water pipes are made of white or light yellow, but this does not affect the water consumption.

The types of water pipes are roughly PPR water pipes, aluminum-plastic pipes, copper pipes, UPVC pipes, stainless steel pipes and so on.

As a new type of water pipe material, PPR pipe has unique advantages, non-toxic, light weight, pressure resistance and corrosion resistance. The interface of the PPR pipe is connected by hot melt technology, and the pipes are completely integrated together, so once the installation pressure test is passed, there will never be water leakage. Moreover, PPR pipes do not scale, and are claimed to never scale, never rust, and never.

Leakage, green high-grade water supply materials. More importantly, such a high-performance water pipe is not expensive at all, and it is very suitable for general home decoration.

When purchasing PPR water pipes, it should be noted that because the production process of PPR water pipes is relatively simple, there are counterfeit products or substandard products on the market, which brings inconvenience to everyone. Therefore, it is recommended that you buy PPR water pipes to regular and reputable sales channels.

Clause. First, it is necessary to carefully observe the appearance, whether the pipe wall is smooth, and the color should be soft and oily;

Clause. Second, it is to try it with your feet, the good ones can be bent but continuously, the nozzle will not crack, and the inferior ones will break when you step on them;

Clause. Third, it is to feel the weight, and the high-quality weight is generally heavier;

Clause. Fourth, look at the hardness, it cannot be deformed by hand;

Clause. Fifth, it can be burned with fire, and there is no peculiar smell and residue when the high-quality PPR water pipe is burned.

Aluminum-plastic pipe is a kind of pipe that was more popular in the past, its light weight, durable and convenient construction, there are many varieties of aluminum-plastic composite pipes currently sold on the market, and the quality and quality are very different. When used as a hot water pipe, due to long-term thermal expansion and contraction, the compression connection may be misaligned and cause leakage. So it's very little used at the moment.

Copper pipe has the advantages of corrosion resistance and sterilization, and is the best product in water pipes. The ferrule is the same as the aluminum-plastic pipe, which has the problem of aging and water leakage for a long time, so most of the users who install the copper pipe use the welded type, and the welding is that the interface is welded together by oxygen. The disadvantage is that it is expensive, and the water supply system in very few communities is copper pipes, which I am afraid will only be seen in export apartments and high-end villas.

UPVC pipe is actually a kind of plastic pipe, the interface is generally bonded with glue, the frost resistance and heat resistance of UPVC pipe are not good, so it is difficult to be used as a hot water pipe, because its strength can not be applied to the pressure requirements of water pipes, so cold water pipes are rarely used. In most cases, PVC pipes are suitable for wire pipes and sewage pipes. In addition, in recent years, it has been found that the additives of UPVC pipes are harmful to the human body and affect development, so it is not recommended to buy.

Stainless steel pipes are too expensive, and the construction is also very difficult, and stainless steel pipes will not be used for general home decoration.

To sum up, whether it is from the product performance or the best considerations, PPR water pipes are an ideal choice. PPR water pipes are reliable in quality and can be completely comparable to copper pipes; There is also ** is relatively easy to accept, the important point is that it is healthy, there is no rust and patina, it is a green and healthy pipe.

The decoration foreman explained the material selection of the sewer pipe, hoping to help you in the decoration.

Stainless steel will be a little better, cost-effective, durable and easy to install. Golden pipe, Yaolong these big names are considered.

The inner wall of the stainless steel water pipe for home decoration is smooth and not easy to scale, and the water pipe is permeable and fluid, with antibacterial properties, and is not easy to breed bacteria. It is currently recognized as a metal material for implantation into the human body in the world. In addition to being beautiful and generous, it can effectively inhibit the reproduction of bacteria in the water, so the state has mandatory the use of stainless steel pipes in some areas and places with high health requirements, such as the Olympic direct drinking water pipeline, the milk factory delivery pipeline, the star-rated hotel, the high-end community, etc.

"At present, the materials of water pipes used in households are: PPR pipes, copper pipes and stainless steel pipes, which are relatively economical, antibacterial and stable can fully meet the standards of household use; The other two are relatively high, and the copper tube with antibacterial performance is definitely the best, and it is also the most expensive; At present, stainless steel water pipes have also begun to move towards families, and the advantages are particularly obvious. "

PPR, PVC and galvanized pipes are now commonly used.

First of all, it is relatively clear to understand the properties of various materials, and then choose them according to their own needs.

All kinds of products have their own advantages and disadvantages, but in general, the most used household water pipes are plastic pipes, stainless steel water pipes, and copper pipes.

The disadvantages of plastic pipes are obvious, and green algae scale will be produced after a long period of use, which is easy to cause secondary water pollution, and the advantage is that it is cheaper.

There is no problem in the performance of stainless steel water pipes, the service life can reach 70 years, the longest is 100 years, of course, relatively speaking, the ** aspect will be more expensive, but it is still more cost-effective when calculated comprehensively.

Copper pipes are generally installed in high-end communities or villas, there is no problem in all aspects of performance, and the service life is also very long, but it is more expensive and has poor thermal insulation performance.

At present, the material of the home improvement water supply pipe with the highest use rate in China is PPR pipe, PE pipe is mostly used in municipal and tooling, and PVC pipe is used more for domestic sewage discharge.

In the past two years, since the first-tier cities, water transformation has been carried out, mainly to replace all the water supply pipes with stainless steel, and use stainless steel water pipes to pass the water to the entrance of the community. Among them, the most advanced is Shenzhen Water, which has been renovated in Futian District to the seventh phase.

If the cost allows, stainless steel water pipes are the most preferred water supply pipes.

Is stainless steel too expensive?

At present, the home decoration water pipe, taking 100 square meters as an example. The flat floor of 2 bathrooms and 1 kitchen needs about 50 80m pipes, and if stainless steel water pipes are used, the maximum amount of labor and materials is 5,000 yuan. If you use plastic pipes, it will be about 3,000 yuan.

Because the amount of home decoration is not large, the material cost is not as high as labor, so the difference in the total price is not as exaggerated as everyone imagined. This increase in the budget means that the whole family has access to healthy drinking water, and the value is self-evident.

Inconvenient installation, want to weld?

In fact, the process of stainless steel water pipes connected by welding is mostly used in sewage pipes, industrial welded pipes and a small number of large-diameter water supply pipes. For the small-caliber pipes (below DN100) for home decoration of ordinary people, the largest and most reliable stability is the double clamping connection method of the national standard. The double clamping connection, simply put, is to press the two ends of the pipe and the pipe fitting connection into a regular hexagonal fix through the clamping tool, so that the pipe and pipe fittings can not be loosened, and then through the middle sealing ring to achieve a completely closed effect.

Will the insulation effect of stainless steel be poor? What should I do if the hot water is not kept warm in the northern winter?

Although the weather is cold and the temperature is low in the north, stainless steel water pipes have begun to be popularized in the north. The stainless steel interior concealment itself has its own thermal insulation effect. If it is outdoors, the pipes and fittings need to be made of polyurethane foam insulation pipes, the insulation effect is not bad, and there will be no risk of ice bursting.

In this way, stainless steel water pipes do not seem to be inconvenient to use, so what are the advantages and benefits of it compared with PPR pipes?

Then this is amazing, I directly sorted it out into a **.

Please click Enter a description.

A little summary:

For the sake of cost savings, PPR pipes are currently the most widely used water supply pipes, and it is more convenient to purchase raw materials and contact with installation masters. If long-term use and drinking water hygiene are taken into account, then stainless steel water pipes are the best choice. After all, spending money to install water pipes is only a temporary thing, but good health is a lifelong thing.
