Stainless steel is recognized as an implantable healthy material, which has been widely used in China and developed countries in the world, and is the "ultimate product" to replace iron and plastic parts. Stainless steel pipes and fittings are recognized as the most environmentally friendly, advanced and scientific products.
First, the advantages of stainless steel water pipes
1, health and health
Stainless steel is a healthy material that can be implanted into human body, so for water supply pipes, stainless steel pipes are the most beneficial to health. The soaking water test shows that all the indexes meet the requirements of relevant national drinking water standards. The inner wall of stainless steel pipeline is smooth, so it won't scale up after long-term use, and it's not easy to be contaminated by bacteria. You don't have to worry about the influence of water quality, and it can also prevent the secondary pollution of water.
2. Pay attention to material selection
All raw materials are made of 304, 304L, 3 16, 3 16L brands, all of which meet the requirements of JIS4305. The above brands have the characteristics of stable performance, high strength and low thermal expansion coefficient.
3. Durable
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, even if they are used underground. The field corrosion test data show that the service life of stainless steel water pipes can reach 100 years, and maintenance is almost unnecessary during the service life, which avoids the cost and trouble of pipeline replacement and has low comprehensive use cost.
4. High temperature and high pressure resistance
Stainless steel can work safely for a long time at the temperature of -270℃-400℃. No matter high temperature or low temperature, harmful substances will not precipitate, and the properties of the material are quite stable. The tensile strength of stainless steel water pipe is greater than 530 N/mm, and it has good ductility and toughness. The high strength of stainless steel water pipe greatly reduces the possibility of water leakage under the action of external force, significantly reduces the water leakage rate, and effectively protects and utilizes water resources.
5. Energy conservation and environmental protection
The inner wall of stainless steel pipeline is smooth and the water resistance is very small, which reduces the pressure loss and transportation cost. Due to the low thermal expansion coefficient of stainless steel, the heat energy loss in hot water pipeline is effectively reduced. Stainless steel material is 100% renewable material and will not cause public hazards to the environment.
6. Wide application range
Stainless steel pipes can be widely used in cold water, hot water, drinking water purification, air, gas, medical gas, petroleum, chemical industry, water treatment and other pipeline systems.
7. Economic applicability
Since the invention of stainless steel in the 20th century, stainless steel has become a common material. At present, among all kinds of water pipes, stainless steel water pipes are the best. This is related to the excellent characteristics of stainless steel, such as corrosion resistance, high strength and strong impact resistance. Its service life can be said to be the same as a building. Once you invest, you will benefit for life, which can be described as "once and for all".
Second, the characteristics of stainless steel water pipes
1, recognized as the most healthy and environmentally friendly material, without pathogenic factors.
2. The material has high strength, excellent corrosion resistance and good heat insulation performance.
3. The connection is safe and reliable, with high strength and vibration resistance. The connection part is "dead" at one time, which effectively avoids the pipeline looseness caused by house vibration, water hammer vibration, pipeline vibration and slight earthquake.
4. The construction is convenient and quick, avoiding complicated and dangerous threading and welding operations on the construction site, and the installation time is only 1/3 of that of threading pipe fittings or welded pipe fittings.
5. Meet the requirements of embedded installation of concealed works.
6. More importantly, during the service life of the building, it is almost unnecessary to maintain and update the stainless steel water pipes.
