Is stainless steel water pipe for engineering better than PPR plastic pipe?

Engineering stainless steel water pipe is better than PPR plastic pipe, this depends on the specific requirements of the project for water pipes, if only the problem is considered, the PPR plastic pipe is lower than the stainless steel water pipe; If you consider quality construction and other issues, it is undoubtedly stainless steel water pipes that are more in line with the standard. (The picture below is a comparison of the performance of stainless steel water pipe and PPR plastic pipe).

Stainless steel water pipes compared to plastic pipes.

Top 10 advantages of stainless steel water pipes.

1. Clean and hygienic, not easy to be polluted by bacteria, no fouling, easy to clean;

2. Long service life. According to the actual corrosion test data, the service life can reach 70-100 years;

3. The life cycle cost is low, almost no maintenance is required, which avoids the cost and trouble of replacing the pipeline, and has significant economy;

4. Save electric energy, the surface of stainless steel is smooth, the friction resistance is small, the water resistance of low flow is only 2 5 of carbon steel pipe, there is no bottleneck resistance, the pump energy consumption is low, and the large-area water supply can save half of the electricity consumption of the pumping station. The flow rate of stainless steel pipes of the same caliber is greater than that of other metal pipes;

5. Save water and energy, significantly reduce the water leakage rate, and effectively protect and utilize water resources;

6. Green and environmental protection, stainless steel can be 100% **, will not cause environmental pollution, is conducive to sustainable development, 7. Stainless steel has a beautiful, clean and fashionable appearance, giving users a high-end feeling. The material is safe and non-toxic, has no effect on water quality, and is harmless to human health.

8. The product is easy to purchase, diverse in form, simple and reliable in installation and construction, firmly connected and without leakage.

9. It is widely used in municipal water supply, pipeline direct drinking water, hot water transportation, medium and high-end building water supply, heating water pipe and steam pipe in the cold area of the north, as well as outdoor pipeline, urban fire water supply, pump room and other places.

10. Stainless steel water pipes are high-grade, but not high-quality, and the investment in choosing stainless steel water pipes is not high, but the service life is long, so that its life cycle cost is low, and it is more cost-effective than any other pipe.

The project is better to choose stainless steel water pipes or PPR plastic pipes, which depends on the specific requirements of the project, but I think that as early as ten years ago, the project chose more PPR plastic pipes, but now, the Ministry of Housing and Urban-Rural Development issued the "Technical Regulations for Buildings and Community Pipeline Direct Drinking Water Systems" in the "Technical Regulations for Buildings and Community Pipelines", which clearly states that plastic pipes are canceled and the use of stainless steel pipes is advocated, which meet the requirements of high-quality pipes of food grade. These industry standards have been introduced and have begun to operate, so now the project requires the use of stainless steel water pipes.

Stainless steel water pipes. The inner wall of the stainless steel pipe is smooth, and it will not accumulate dirt for long-term use, and it is not easy to be stained by bacteria, so there is no need to worry about the water quality being affected, and it can also eliminate the secondary pollution of water. The thin and dense chromium-rich oxide film on the surface of stainless steel makes stainless steel water pipes have good corrosion resistance in all water quality, including soft water, and excellent corrosion resistance even when used in the ground.

Precautions for the installation method of stainless steel water supply pipe.

1. When installing stainless steel water supply pipes, pay attention to distinguishing between cold and hot water pipes, because the wall thickness of cold water pipes and hot water pipes is different.

2. Before installing the stainless steel water supply pipe, pay attention to check whether the water pipe and fittings are leaked or damaged. The connection between the stainless steel water supply pipe and the fittings must be firm, and attention should be paid to it when installing.

3. When installing the stainless steel water supply pipe, the water pipe wiring diagram should be drawn to facilitate future maintenance.

Which is better, stainless steel water pipe or PPR plastic water pipe, the following is a comparison of the advantages and disadvantages of the two:

Advantages and disadvantages of stainless steel pipe water pipes:

Advantages of stainless steel water pipe: 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.

Disadvantages of stainless steel water pipes: the manufacturing cost is relatively high.

Advantages and disadvantages of PPR tubes:

Advantages: The interface of the PPR pipe adopts hot melt technology, and the pipe can be connected with the pipe and the pipe fittings at the interface after the hot melt connection, and the integrity is good, so once the installation pressure test is passed, it will not exist like the aluminum-plastic pipe after a long time of aging and water leakage. **Moderate, stable performance, heat-resistant, corrosion-resistant, impermeable, service life of 15-30 years.

Disadvantages: long use time will be scaling, moss, secondary pollution of water quality, affect water quality, connection surface needs to be heated, heating time is too long or socket insertion is too long, will cause water flow blockage, easy to leak.

Stainless steel water pipes are recommended.

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.

At present, the material of home improvement water pipes commonly used in China is mostly PPR, but stainless steel pipes are more widely used abroad. Of the two, who is more successful and more promising?

In terms of performance, PPR water pipe is not like PVC water pipe, which will age and leak after a long time, it is environmentally friendly and non-toxic, can be used as a cold water pipe, can also be used as a hot water pipe, and has greater toughness, is not easy to break, and is more durable. But after a long time, PPR water pipe is different from stainless steel water pipe, it has no self-cleaning and sterilization function, and it is easy to cause damage to human health when used for a long time.

In comparison, stainless steel water pipes have stronger seismic resistance, wear resistance and temperature resistance than PPR water pipes, and have the functions of self-cleaning and preventing bacterial growth. Stainless steel pipes are mostly made of food-grade materials, so the cost is high, and many families are discouraged. If the ** can be reduced, I believe that the penetration rate will be greatly improved.

From the point of view of use, if it is buried in the wall, the PPR hot melt pipe is chemically stable, easy to maintain, you can choose the PPR water pipe, if it is installed outside the wall, the stainless steel pipe has a beautiful appearance, easy to take care of, is not easy to rust, durable, and will be a better choice.

What material to choose, according to the actual situation of each person, but the popularity of stainless steel water pipes will be the general trend.

If it is concealed in the wall, it is recommended to use PPR hot melt pipe, because it does not rust and rot, is not easy to get out of joint, or causes water leakage due to thermal expansion and contraction. If you don't buy counterfeit and shoddy products, you can generally guarantee them for 50 years.

If you can see it clearly, of course, it is good stainless steel, beautiful and generous, easy to repair, and you can hang a small pendant or something, which is quite emotional. Although the price difference is 10 times, the amount of residential bathroom is not large. Stainless steel pipe can also choose threaded connection, and ordinary galvanized steel pipe construction process is similar, but the material is different, it should be noted that stainless steel pipe is also divided into welded pipe and wire buckle pipe, don't make a mistake when buying, it is best to ask a qualified decoration company to work together, the quality should still be ***.

It can also be used as a dark compress).

You can also choose the sanitary stainless steel compression sleeve type quick installation pipe, which is very beautiful, and a set of toilets can be installed in 20 minutes.

Stainless steel water pipes are better when compared with the two. There are several reasons for this:

Stainless steel water pipes.

1. Eliminate secondary pollution of water quality: the inner wall of the stainless steel pipeline is smooth, and it will not accumulate scale and be easily stained by bacteria for long-term use, so there is no need to worry about the water quality being affected, and it can also eliminate the secondary pollution of water.

2. Stable performance: all raw materials for water supply pipes are made of stainless steel with a grade of l l, which has the characteristics of stable performance, high strength and low thermal expansion coefficient. Stainless steel can work safely for a long time at a temperature of -270 400, no harmful substances will be precipitated at high or low temperatures, and the material properties are quite stable.

3. Good corrosion resistance: the thin and dense chromium-rich oxide film on the surface of stainless steel makes the stainless steel water pipe have good corrosion resistance in all water quality, including soft water, and excellent corrosion resistance even if it is buried.

4. Long life: Field corrosion test data show that the service life of stainless steel water pipes can reach 100 years.

5. Low comprehensive use cost: there is almost no need for maintenance during the life cycle, which avoids the cost and trouble of pipeline replacement, and the comprehensive use cost is low; The stainless steel pipe has a smooth inner wall and very little water resistance, which reduces pressure loss and reduces transportation costs.

6. Environmental protection and renewable: the tensile strength of stainless steel water pipe is greater than 530n mm, and it has good ductility and toughness. The high strength of stainless steel water pipe greatly reduces the possibility of water leakage affected by external force, significantly reduces the leakage rate of water, and enables water resources to be effectively protected and utilized.

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.

PPR Water Pipes:

1. The inner wall of the PPR pipe is seriously polluted.

The PPR plastic pipe itself is non-toxic and meets the requirements of hygiene, but the PPR plastic pipe does not have the function of self-cleaning and killing bacteria, it is a breeding ground for bacteria, and long-term use will endanger human health and become a new threat to human health and potential life.

2. Production hazards.

Due to the low production threshold for the production of plastic water pipes, there are hundreds of thousands of can be put into the production line, some companies ignore industry standards, in order to fight for the market, do not add additives in proportion, too many additives are harmful to the human body.

3. Short service life.

After the plastic pipe is heated and expanded, it cannot be restored to its original state, which means that the molecular structure of the plastic has changed, which is brought about by the change of water temperature. The consequence of this change is that the plastic cracks and has a much reduced lifespan. Once repairs are initiated, more capital costs will be invested.

Part of this article is about the PPR tubes that are currently used in most of our country's home improvements, and it is not a complete disparagement of PPR. To sum up, compared with the two, stainless steel water pipes are better.

Stainless steel water pipes are better

Features of plastic water pipes;

1.Plastic water pipes have poor safety and durability.

The plastic pipes are hot-melt connected. This connection method is not easy to control its temperature, the temperature is too low, and the connection is not strong and will 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 equivalent to secondary use plastic after remelting, which is the weak point in the piping system.

2.The pressure bearing is relatively low, and it is generally only allowed to be used in occasions within the working pressure. At the same time, the linear expansion coefficient of the plastic pipe is large (and technical measures must be taken to prevent the expansion and deformation of the pipe when the pipe is surface-mounted or non-directly buried and concealed. When conveying hot water, it is easy to detach at the interface.

3.Plastic water pipes have low hygienic properties.

The plasticizers and antioxidants that must be added to the production of plastic pipes are carcinogenic to the human body. It has a great impact on the kidneys and liver in the human body, which can lead to cancer, kidney damage, damage to the body's functional reengineering system, and affect development.

4.The service life is short, generally 5-15 years service life, and the maintenance cost is high.

Features of stainless steel water pipes:

1.Health and hygiene, pay attention to the selection of materials.

Stainless steel material is a healthy material that can be implanted into the human body, the inner wall of the pipeline is smooth, and it will not accumulate dirt after long-term use, and it is not easy to be stained by bacteria, so there is no need to worry about the water quality being affected, and it can also eliminate the secondary pollution of water.

The material is superior, the pipe fittings are mainly made of 304 (or 316) stainless steel, and the sealing ring is made of silicone rubber, which has good temperature resistance.

2.Durable, energy-saving and environmentally friendly.

The service life of stainless steel water pipes can reach 100 years, and there is almost no maintenance required during the life cycle, which avoids the cost and trouble of pipe replacement, and the comprehensive use cost is low.

Stainless steel is 100% renewable and will not cause harm to the environment.

3.It is resistant to high temperature and high pressure, and has a wide range of use.

Stainless steel can work safely for a long time at a temperature of -270 -400, and the tensile strength of stainless steel water pipe is greater than 530 Nmm, which greatly reduces the possibility of water leakage under the influence of external forces, so that water resources can be effectively protected and utilized.

Stainless steel pipes can be widely used in cold water, hot water, drinking water purification, air, gas, medical gas, petroleum, chemical, water treatment and other pipeline systems.

4.Economical and practical.

Stainless steel has a long service life, up to 100 years, stainless steel has zero maintenance, and it benefits for life when used once.
