Water pipes are mainly divided into galvanized pipes, UPVC pipes, plastic pipes, PPR pipes, copper pipes and stainless steel pipes. One: Galvanized pipes: Most old houses are galvanized pipes, and now iron pipes for gas and heating are also galvanized pipes.
This is a water pipe. After several years of use, a large amount of rust scale is produced in the pipe, and the yellow water flowing out is not only polluted, but also mixed with fine particles bred by the unsmooth inner wall.
Bacteria and rust lead to high content of heavy metals in water, which seriously harms human body. In the sixties and seventies, developed countries began to develop new models and gradually banned galvanized pipes. China Ministry of Construction and other four ministries also issued a document saying that galvanized pipes have been banned since 2000, and new residential areas are being built.
Galvanized pipes are rarely used for cold water pipes, and galvanized pipes are used for hot water pipes in some communities. Two: UPVC pipe: actually, it is a kind of plastic pipe, which is usually connected at the interface. The frost resistance and heat resistance of UPVC pipe are not good, so
It is difficult to be used as a hot water pipe, and cold water pipes are rarely used, because the strength can not meet the pressure requirements of water pipes. In most cases, PVC pipes are suitable for electric wires and sewage pipes. In addition, in recent years, scientific and technological circles have discovered chemical additives that can make PVC softer.
Phthalein has a great influence on kidney, liver and testis in human body, which will lead to diseases and kidney damage, destroy human functional reconstruction system and affect development. therefore
I suggest you not buy it. Three: aluminum-plastic pipe: aluminum-plastic composite pipe is a popular pipe in the market. At present, Rifeng and Jinde are well-known in the market.
It is light, durable and convenient to construct, and its flexibility is more suitable for use in construction. Its main disadvantage is that when it is used as a hot water pipe, it is made of
Long-term thermal expansion and cold contraction will cause dislocation of the pipe wall and cause leakage. Many residential areas in Beijing use aluminum plastic pipes. Comparison of decoration concepts
In new Guangdong and Shanghai, the market for aluminum-plastic pipes has gradually disappeared. At present, aluminum-plastic pipes are still active in the Beijing market. I believe in the near future.
In the future, the aluminum-plastic pipes in Beijing market will also face elimination. 4.PPR pipe: As a new type of water pipe material, PPR pipe has unique advantages, which can be used as both cold water pipe and cold water pipe.
As a hot water pipe, it is becoming a popular material because of its advantages of light weight, pressure resistance and corrosion resistance, and is currently selected in decoration projects in Beijing.
PPR pipes are not only suitable for cold water pipes, but also for hot water pipes and even pure drinking water pipes. Using PPR pipe interface
Using hot-melt technology, the pipes are completely fused together, so once installed and pressed, they will not exist for a long time like aluminum-plastic pipes.
In order to avoid aging and water leakage, PPR plastic pipe itself is not toxic, but with the increase of use time, it has no self-cleaning function and
PPR plastic material has bactericidal function, which has become a gathering place for secondary pollution of water quality and a breeding ground for bacteria, seriously threatening human health. Five: copper pipe: copper pipe has the advantages of corrosion resistance and sterilization, and is the first-class product in water pipes. There are two ways to connect copper pipes: clamping sleeve and clamping.
Casing, like aluminum-plastic pipe, has the problem of aging and water leakage for a long time, so in Shanghai and other places, users who install copper pipes mostly use welding.
Type B, welding means that the joints are welded together with oxygen, so that it will never leak like PPR water pipes, which is a disadvantage of copper pipes.
Heat conduction is fast, so the hot water pipes produced by well-known copper pipe manufacturers are covered with plastic and foaming agent to prevent heat dissipation. Other copper pipes
One disadvantage is that it is expensive, and the water supply system in few communities is made of copper pipes. I'm afraid it will only be seen in export apartments and high-end villas.
Here you are. If you plan to change the water pipe and think the copper pipe is good, it is recommended to use the welded joint. Six: stainless steel pipes: stainless steel materials are recognized as healthy materials that can be implanted into the human body, and water pipes are all stainless steel.
Up to now, the country has many years of successful application records, and it has become the current trend and development direction. Stainless steel material is safe and nontoxic, and will not
It will not cause secondary pollution to the water quality, keep the water quality pure and hygienic, and the hygiene and safety are completely guaranteed. Minle stainless steel water pipes and fittings are adopted in China.
The patented technology ensures that the thin-walled stainless steel water pipe can withstand the pressure of 1.6Mpa under the condition of careful installation, which is in line with the national industry.
The service life of stainless steel pipe in Minle can reach 100 years by adopting the pressure standard of stainless steel pipe, while the general tap water pressure is 0.3-0.6Mpa.
Almost no maintenance is needed in the cycle, which avoids the cost of pipeline replacement, and the comprehensive use cost (calculated according to the service life of 70 years) is only galvanized.
1/2 for pipes, 1/4 for high-quality PPR and 1/2 for copper pipes. Seven: Thin-walled stainless steel pipes are safe, reliable, hygienic, environmentally friendly and economical. They are suitable for high-quality drinking water systems, hot water systems and water supply systems with safety and hygiene as the first priority. Engineering practice at home and abroad proves that the water supply system has the best comprehensive performance and is novel and economical.
One of the energy-saving and environment-friendly pipes is also a very competitive water supply pipe. Stainless steel pipes will definitely improve water quality and people's health.
The standard of living plays an unparalleled role.
What kind of water pipes do they install better?
And then what? At present, PPR hot-melt pipes are very popular. At present, PPR pipes are widely used in home decoration, including hot and cold water pipes, which are non-toxic and safe, resistant to high temperature of 95℃, hot-melt connection, and the joints are not easy to leak, convenient and reliable, convenient for construction and transportation, so most of them are used in home decoration. Brand recommendations with good reputation now: Jinde, Jinniu, Rifeng, Cai Zhong, Band-Aid, Pirsha, Wei Xing and Gu Meier. I wish you a happy decoration! Hope to adopt
