Why are stainless steel water pipes used, which one is better than steel pipes and stainless steel w

Because stainless steel water pipes have many advantages, and the state has newly introduced a policy to require stainless steel water pipes to be selected for indoor water supply systems.

At present, the state has issued a new building standard, requiring the use of stainless steel pipes in indoor water supply systems.

Although the unit price of stainless steel water pipe is more expensive than that of PPR, in the long run, the service life of PPR water pipe does not exceed 30 years, and the pressure resistance is weak, the water leakage rate is particularly high, and it is easy to breed harmful substances. Once the maintenance is carried out, not only the amount of work is large, but also doubled.

The stainless steel water pipe, with a service life of at least 70 years, has the same life as the building, and is installed at one time, almost no maintenance, low cost, and is very cost-effective, safe and hygienic.

Stainless steel water pipe is a trend in the development of the water pipe industry, the state also has documents to vigorously promote the development of stainless steel water pipes, stainless steel manufacturers around the country have sprung up, many plastic pipes have been changed to stainless steel pipes. Moreover, stainless steel is durable, and the two most basic features of hygiene have also benefited many families.

Because stainless steel water pipes are healthy, environmentally friendly, reliable and economical. Like Jie housekeeper stainless steel water pipe, the pressure resistance is large. It has a low thermal conductivity, is a good thermal insulation effect, and can be used for a long time in the temperature range of -40 120.

The performance of stainless steel water pipes is better than that of PPR water pipes, which is recognized by the public. ** It will be higher than PPR water pipes, but in terms of life, the cost performance is very high.

There are probably three issues that ordinary residents are most concerned about:

** Stainless steel water pipe ** is indeed much higher than PPR, but in the long run, PPR water pipe for 10 years and 8 years, it is easy to have various problems such as water leakage and yellow water, and the cost of frequent replacement and maintenance is more cost-effective than buying stainless steel water pipe at one time.

Health Stainless steel water pipes can be said to be better than PPR in terms of health, and the penetration rate of stainless steel water pipes in Tokyo, Japan is close to 100%, and it is known as the "best drinking water container material" in Japan. No harmful substances will be precipitated.

Quality In terms of quality, stainless steel is resistant to high temperature and high pressure, which is much higher than PPR water pipes.

The development of domestic home improvement water supply pipes, from galvanized pipes - pvc-u pipes - aluminum-plastic pipes - ppr pipes - thin-walled stainless steel water pipes. The national standard (building water supply and drainage design standard GB50015-2019), which will be implemented on March 1, 2020, requires that indoor water supply pipes should use stainless steel pipes and other corrosion-resistant, convenient and reliable pipes for installation and connection!

Stainless steel pipes have become the choice of more and more families who pay attention to health and environmental protection, and protect the health of drinking water and the safety of domestic water for the next few decades!

The first choice of Daming stainless steel water pipe will be so: safe, clean, hygienic and durable!

Stainless steel water pipes are the best direct drinking water pipes. It has a very low water leakage rate and can save valuable water resources. In the 80s of the last century, the water pipe leakage rate was about 17%, and the water leakage rate dropped to 7% after switching to stainless steel water pipes.

Jiangte pipe industry will answer for you, the use of stainless steel pipe material is different, and it cannot be simply said that the material is good. Commonly used are 430, 201, 301, 304, 321, 316, etc., as long as the material is no problem, the others are similar, the steel pipe is divided into seams and seamless, seamless is better than seams, and it is also a little more expensive, it is recommended to buy seamless, mainly depending on the working conditions.

Compared with copper pipes, stainless steel pipes can achieve the requirements of thinning wall thickness, and conform to the industrial policy of material saving and energy saving, and have the guarantee of strength, and can achieve the purpose of reducing the load-bearing of buildings. Stainless steel pipes are especially suitable for hot water transportation due to their good thermal insulation performance, whether it is the thickness of the insulation layer, or the construction and maintenance costs of the insulation structure, etc., the thin-walled stainless steel pipes have good economy. In addition, the equivalent roughness of the inner wall of the thin-walled stainless steel pipe is KS, which is smaller than that of the copper pipe, and in the case of the same caliber, the hydraulic performance is good and the flow rate is large.

The stainless steel water pipe has superior health performance, eliminating the problem of "red water, blue and green water and hidden water", no peculiar smell, no scaling, no precipitation of harmful substances, keeping the water quality pure, harmless to the human body.

However, copper pipes have the problem of excessive copper, the problem of blue-green water caused by corrosion, the corrosive bitter odor generated, and the phenomenon of scaling.

The inner wall of the stainless steel water pipe is smooth, and the water resistance is very small, which reduces the pressure loss and reduces the transportation cost. Due to the low coefficient of thermal expansion of stainless steel, the heat loss in hot water pipes is effectively reduced. Stainless steel is 100% renewable and will not cause harm to the environment.

Personally, I feel that it is better to use plastic pipes for tap water inlet pipes, because if stainless steel is used, it is still easy to have some peculiar smells.

What is the difference between plastic pipe and stainless steel pipe? In fact, it is the problem of drinking water cleaning, if the water supply company normally supplies water, mold or moss will be formed in the plastic pipe within 5 years, and the poor quality of the plastic pipe itself contains a small amount of toxic substances, and the quality of your drinking water may be discounted, so many people will install a water filter for this reason.

In addition to the easy installation of stainless steel pipes, there will be no problem of poor water quality, of course, the premise of 316 is guaranteed, and 304 is used to make water pipes, in fact, corrosion resistance is really a big problem. This is also the focus of the vigorous promotion of stainless steel water pipes for home improvement.

However, there is a noteworthy place, tap water supply is not directly water quality treatment on the flow to your home, which also has to pass through the water supply pipeline, community reservoir and other places, I am sorry to tell you, for cost considerations, these are used ordinary iron pipes, since the water source from the water plant to your home can not be guaranteed, in fact, no matter how good your home water pipe is, the water quality can not be guaranteed. The main thing in the home is still the water purification filter.

The water inlet pipe must be better with stainless steel, this because it is not easy to rust, and durable, once done, there will be no trouble behind, after this thing is sealed, if it is removed later, it is more troublesome, plastic pipe, he must be cheaper, but this process is also prone to failure, if you rule it out, the cost will be relatively high, it is better to use it for stainless steel at one time.

Stainless steel pipes are better.

In terms of quality alone, regardless of cost, stainless steel pipes are definitely better than plastic pipes. The pressure-bearing grade of stainless steel pipes, the deformation resistance of pipes are very good, and the stainless steel is not easy to form colonies, which is also better in drinking water hygiene.

The disadvantage is that the cost is high and the construction is slow.

The inlet pipe of tap water should still use plastic pipes, and stainless steel pipes are easily eroded by tap water and disinfectant substances in the middle.

The plastic inlet pipe is better, and the stainless steel one will have other reactions due to water precipitation.

Stainless steel is better, so that it is durable and does not age.

Waterway construction is an important event in home decoration. Once construction is complete, these pipes may end up buried in the ground, making repairs especially difficult to repair if something goes wrong. Therefore, in the decoration process, you should have a preliminary understanding of the material of the water pipe.

Let's follow Jin Jin to find out.

1.How to choose the material of the water pipe? plastic or stainless steel.

1) Plastic water pipes.

In home renovation, it occupies the majority, and PPR water pipes are commonly used. It is non-toxic, odorless and non-polluting, and the material is compressive and corrosion-resistant, and will not rust.

PPR water pipes are usually divided into hot water pipes and cold water pipes, and it should be noted in the selection that the hot water pipes can choose single-layer pipes with high heat resistance, and the cold water pipes can choose double-layer pipes with antibacterial effect.

2) Stainless steel water pipes.

The appearance is more high-grade and beautiful, and its degree of pressure resistance and corrosion resistance is stronger than that of PPR water pipes. Moreover, the stainless steel water pipe is hard and not easy to deform, and it is suitable for conveying both cold and hot water.

Its inner wall is smooth, not easy to produce scale pollution, and it is not easy to age and rust, and has a long service life. Stainless steel water pipes have strong pressure resistance, and are also more suitable for homeowners who live in high-rise buildings.

2.Advantages and disadvantages of plastic water pipes and stainless steel water pipes.

1) The plastic water pipe is economical and suitable for general home decoration. However, its drawbacks are also obvious. First of all, the service life of plastic water pipes made of PPR material is short, and the cost of replacement and maintenance is high. Secondly, long-term heating can easily deform the water pipe, which may lead to water leakage and other hazards over time.

2) Stainless steel water pipes will be higher than plastic water pipes**, but the durability will be higher. And after installation and molding, it is not easy to leak water and other conditions.

3.Precautions.

After reading the above differences, you should have an understanding of the two. Here are some precautions for the purchase and installation of water pipes:

1) Pay attention to the quality and size specifications when purchasing. No matter which kind of water pipe you buy, you must distinguish between regular and inferior quality, and at the same time pay attention to the size and specifications of the pipe, so that there will be no mistakes when connecting.

2) When installing waterway pipes at home, you can choose to route the lines on the roof. In this way, even if there is any problem in the later stage, it can be detected in time and will not affect the downstairs neighbors.

3) When the waterway pipeline is accepted, the pressure test should be carried out first to test whether the pipeline leaks; Secondly, check whether the pipeline is horizontal and vertical, and whether the spacing between the cold water pipe and the hot water pipe is up to standard.

Water is inseparable everywhere in life, choose safety.

For this kind of water inlet pipe, it is better to use stainless steel.

Because stainless steel itself will have a stronger corrosion resistance, then its overall life will be better, and it can be used in various occasions.

This inlet pipe if you don't take into account the cost. It's better to be stainless steel. Especially 304 stainless steel.

He neither rusts nor rots. And it's also stress-resistant. So it is not easy to break.

Second, the plastic ones will not work. plastic to a certain age. It will take care of itself.

Decay. There are also plastic ones that are not crush-resistant. If.

If you are under heavy pressure. It will break immediately. But the cost of plastic is particularly low.

Therefore, plastic pipes are now used in construction in many places.

Stainless steel is good.

Stainless steel pipes have the longest service life. From the analysis of the use of stainless steel abroad, the service life of stainless steel water pipes can reach 100 years, which is as long as the life of buildings. The life of plastic pipes is difficult to determine in China, largely depends on the production process technology and the quality of raw materials, the quality is uneven, the high-quality pipes of large enterprises can reach up to 25 to 30 years, and the life of fake and shoddy pipes may only be a few years.

The aging problem of plastic pipe is more prominent, sunlight, temperature, chemicals, mechanical factors, time will cause its aging, aging plastic is prone to occur under the impact of water pressure and water hammer, and the service life is greatly reduced. In addition, the hot melt joining method is prone to water leakage or material deterioration at the joint.

Of course, it is a stainless steel water pipe, because the safety and reliability of the plastic water pipe is poor, the sanitary performance is low, it is not easy to control its temperature, the temperature is too low, and the connection is not strong to leak; If the temperature is too high, the plastic material will deteriorate badly, and the joints will be brittle. Even with good temperature control, the plastic at the joints is effectively reused after remelting.

And stainless steel water pipe is a safe and non-toxic healthy material that can be implanted into the human body. The inner wall of the stainless steel water pipe is smooth, it will not scale for long-term use, and it is not easy to be polluted by bacteria, which can avoid secondary pollution of water quality and do not have to worry about the impact of water quality. The strength of stainless steel water pipe is high, it is 3 times that of copper pipe, 8-10 times that of plastic pipe, the thermal conductivity of stainless steel water pipe is low, the thermal insulation performance is 25 times that of copper pipe, corrosion resistance, and the service life is as long as 700-100 years.

Hello, the water pipe is of course better with a stainless steel pen with plastic, because the plastic one is easy to crack and explode in winter.

The plastic is good, and now there are more PPR pipes, and the iron is more likely to rust, and the quality of the water is more easily affected, and the service life is relatively short. However, the aluminum-plastic pipe is better than PPR, and the compressive and corrosion resistance are better than PPR, but the cost of the aluminum-plastic pipe is relatively high, and the supporting pipe fittings are copper pipe fittings or clamping parts, which are much higher than PPR's pipe fittings, and PPR will produce scale inside the water pipe for a long time, thus multiplying a large number of bacteria and affecting human health. In the past, the pipes used for water supply were mainly cast iron pipes.

Sand molded cast iron pipes are mainly used for the exterior and galvanized cast iron pipes are used indoors. However, after a few years of use, it is easy to produce a large amount of rust and scale, breeding bacteria, and seriously endangering human health.

If I had to choose, I think it would be stainless steel, which is better, because the effect of stainless steel is very good, and it is used. The cost is also very low.
