1. According to the field corrosion test data, the service life of stainless steel water pipes is as long as 100 years;
2. Stainless steel has high strength, which is 3 times that of copper pipe and 8 ~ 10 times that of PP-R pipe, and can withstand the impact of high-speed water flow of 30 meters per second;
3. It is the most sanitary water pipe, without corrosion and excessive exudation, and can achieve zero pollution;
4. Low thermal conductivity, good thermal insulation performance, 4 times that of iron pipe and 25 times that of copper pipe, especially suitable for hot water pipes.
5. Hygiene and non-toxic: 304 stainless steel sanitary pipe is recognized as a healthy material that can be implanted into human body, and it is an environmental protection and sanitary material in 2 1 century. Stainless steel water pipes have been successfully applied in developed countries for many years. Cast iron pipes are easy to corrode and rust, which affects health, and plastic pipes are easy to produce toxic gases.
Second, the advantages of connection technology
1. The card connection technology specially used for connecting stainless steel water pipes has won many national patents, which abandons the disadvantages of traditional connection methods, and is convenient and fast in construction and reliable and safe in connection;
2. the sealing performance is greatly improved, and the working pressure can reach 2.5MP (tap water pressure is only 0.3 ~ 0.6 MP), which can be maintenance-free for life;
3. Advanced mechanical pressure sealing technology enables each joint to have several millimeters of space for thermal expansion and cold contraction, so it can completely eliminate the hidden danger that other threaded connections, welding, rubber hoses and other joints tear due to thermal expansion and cold contraction, and can be safely used in the environment with temperature difference of -40℃ ~ 120℃ 160℃. (According to the national standard GB5026 1-XX, it is forbidden to weld metal water pipe joints).
4. Convenient connection: the connection mode of 304 stainless steel pipe is card connection, which has the advantages of low cost, high speed, simple operation, safety and reliability. The ABS pipe is bonded with ABS sol; However, cast iron metal pipes are generally connected by threads, which is easy to leak, while other stainless steel pipes are connected by welding, which has high cost and long construction time.
Third, the advantages of beautiful appearance
The surface of stainless steel is as bright as a mirror, shining with silver, which is especially suitable for the exposed installation of kitchen and bathroom water pipes. In the renovation of old houses, it is not necessary to knock down the old water pipes, but only to install stainless steel water pipes on the wall, which is not only beautiful and luxurious, but also can be used as shower curtain rods and towel racks, which PP-R pipes and copper pipes can't do.
Fourth, the advantage of cost performance.
Although on the surface, stainless steel water pipes are much more expensive than PP-R pipes and similar to copper pipes, the service life of stainless steel water pipes is calculated by people who can calculate accounts as 100 years. After calculation, stainless steel water pipes do not need maintenance for life, and there is no possibility of property loss at home caused by water leakage. Is it worth spending an extra thousand dollars?
Verb (abbreviation of verb) environmental advantages
Waste stainless steel water pipes and spare parts can be recycled without any waste polluting the environment. In contrast, PP-R tube eventually pollutes the environment with white waste (refractory polymer waste), while copper tube pollutes the environment with toxic copper oxide. From the above analysis, it is indeed a wise decision with far-reaching significance for the leaders of the Ministry of Construction to give priority to stainless steel water pipes.
6. It is the general trend that stainless steel water pipes will eventually eliminate all other water pipes.
Experts predict that water supply pipelines will eventually return to the era of metal pipes, and stainless steel pipes have the best comprehensive performance among all metal pipes.
People in developed countries generally choose stainless steel water pipes. In 2000, more than 80% residents in Tokyo, Japan replaced the original PP-R pipes and copper pipes with stainless steel pipes.
With the improvement of people's living standards and concern for health, it will be an indisputable fact that stainless steel water pipes will become the first choice for home improvement. Family decoration requires health and environmental protection. Nowadays, many families pay great attention to the environmental protection of decorative materials in the process of decorating new houses and transforming old houses. In particular, water pollution poses health risks to our daily life, which is an inevitable problem. How to protect the environment of home decoration materials is a problem that every family must consider. Stainless steel sanitary pipe is the most healthy and environmentally friendly water supply material for water pipe renovation.
