Question 2: Which brand of domestic tap water pipe is of good quality? How to choose the material of the water pipe in home decoration
The selection and installation of the water pipe in the "concealed project" has become an issue that cannot be ignored in decoration. At the same time, in order to make the room beautiful, people generally use buried wall construction for water pipes when decorating. However, once the water pipe leaks and bursts, it will bring irreparable consequences. Perhaps some consumers have been deeply affected by this annoying "trauma".
The reasons may come from the following aspects: First, the plastic pipes used are not qualified products. There are some inferior products with poor quality and cut corners in the market, such as the compression resistance and cold thermal expansion coefficient can not meet the requirements, and the construction is not standardized, which will definitely have problems in engineering. Secondly, the physical and chemical characteristics of the plastic pipe itself determine that because the plastic pipe is connected by metal at the corner, the plastic pipe and the metal are not welded or screwed, but bonded by special glue. In the case of large temperature difference, such as sudden cooling, the thermal expansion coefficient between plastic and metal is different, and the glue is easy to crack, thus causing the water pipe to burst. Third, the aging of plastic water pipes. Because plastics contain "plasticizer", it will escape with time and lead to the hardening and embrittlement of plastics. Sunlight will also age plastics, and ozone in the atmosphere will also damage plastics. Aging plastic pipes are prone to burst under the shock of water pressure and water hammer.
according to relevant surveys, there are mainly galvanized steel pipes, PAP (aluminum-plastic composite pipe), PPR (polypropylene ester composite pipe) and UPVC (polyvinyl chloride composite pipe) in the current market, as well as some copper water pipes and plastic-lined thin-walled stainless steel pipes with good quality and performance. Galvanized steel pipes are not corrosion-resistant and antibacterial, and the inner wall has poor scaling resistance. After water contacts with the inner wall of the pipeline for a long time, it is easy to rust into the water, causing direct pollution of drinking water. At the same time, because it is a threaded connection, it is easy to loosen and leak after a long time. Therefore, in 2, the country banned the use of cold galvanized steel pipes, and hot galvanized steel pipes were also used within a time limit.
according to statistics, in some developed countries and regions, copper water supply and heating systems have accounted for a large proportion, with the United States accounting for 81%, Canada accounting for 85%, Australia accounting for 85%, Britain accounting for 95%, Hong Kong accounting for 7% and Singapore accounting for 67%. In recent years, copper pipes have also begun to attract people's attention in China. In the past, copper pipes were only used in star-rated hotels and high-grade office buildings, but now it has become popular to use copper pipes in houses.
Copper pipes have excellent properties that other pipes don't have, such as sanitation and health. Copper can inhibit the growth of bacteria, and 99% of bacteria disappear after entering the copper pipes for 5 hours, thus ensuring the cleanliness of drinking water. And durable, strong safety performance, life-long maintenance-free However, the price of copper pipes will be slightly higher. For example, it costs about 1 yuan to decorate a two-bedroom apartment with ordinary pipes, while it costs about 13 yuan to use copper pipes with good performance.
varieties of water supply fittings
in the past, the pipes used for water supply were mainly cast iron pipes. Sand cast iron pipes are mainly used outdoors, and galvanized cast iron pipes are used indoors, which can be divided into cold (electric) galvanized and hot-dip galvanized. China has stipulated that sand casting process pipe fittings and cold galvanized cast iron pipes will be eliminated from June 1st, 2, and the use of hot galvanized cast iron pipes will be gradually restricted, and aluminum-plastic composite pipes and plastic pipes will be popularized. Therefore, there are three main types of pipelines currently in use. The first category is metal pipes, such as hot-dip cast iron pipes lined with plastic, steel pipes and stainless steel pipes. The second category is plastic-clad metal pipes, such as plastic-clad steel pipes and aluminum-plastic composite pipes. The third category is plastic pipes, such as PP-R (cross-linked polypropylene high-density network engineering plastic).
the state also stipulates that all kinds of pipes and fittings involved in drinking water pipelines must have the approval of the health department before they can be sold.
Code and meaning of commonly used plastics in water supply pipeline:
PP-R cross-linked polypropylene high-density mesh engineering plastic
PE high-density polyethylene
PP polypropylene
PB polybutene
PEX cross-linked polyethylene
Comprehensive performance requirements of water supply pipeline:
As a water supply pipeline, it requires hygiene, safety, energy saving and convenience. Therefore, the inspection of a pipeline should be started from four aspects. That is, hygiene: pipes and fittings must have no harm to human body. Safety: It has sufficient strength, excellent mechanical properties, aging resistance and heat resistance. Energy saving: smooth inner wall, corrosion resistance, small resistance to fluid and good thermal insulation performance. Party ... > >

question 5: what kind of water pipe is good for home improvement? What are the top ten brands of water pipes for house decoration? Generally, people need PP-R water pipes in their lives, and house decoration water pipes are an important process of home improvement! You can't live without it.
most of the water pipes used now are PVC and PP-R pipes. Because of their high cost performance, most families use the former. The quality of PP-R pipes is more secure and its applications are more extensive.
It is just more expensive. With people's attention to product quality, now more and more families and offices choose PP-R water pipes. Several aspects that need attention, now let's analyze: What water pipes are good for home improvement?
Water pipes are mainly divided into galvanized pipes, UPVC pipes, plastic pipes, PPR pipes, copper pipes and stainless steel pipes.
galvanized pipe: galvanized pipes are mostly used in old houses. Now, the iron pipes used for gas and heating are also galvanized pipes, and galvanized pipes are used as water pipes. After several years of use, a large amount of rust scales are produced in the pipes, and the yellow water flowing out is not only polluted, but also mixed with fine
bacteria bred on the unsmooth inner wall. Corrosion causes high heavy metal content in the water, which is seriously harmful to human body. In the sixties and seventies, developed countries began to develop new models and banned galvanized pipes one after another. The Ministry of Construction of China and other four ministries and commissions also issued a document explicitly prohibiting galvanized pipes from 2. At present, galvanized pipes are rarely used for cold water pipes in newly-built residential areas, and galvanized pipes are used for hot water pipes in some residential areas.
UPVC pipe: actually, it is a kind of plastic pipe, which is usually connected at the joint. The frost resistance and heat resistance of UPVC pipe are not good, so
it is difficult to be used as hot water pipe, and cold water pipe is rarely used because its strength cannot meet the pressure requirements of water pipe. In most cases, PVC pipes are suitable for electric wires and sewage pipes. In addition, in recent years, the scientific and technological circles have found that the chemical additive < P > phthalein, which can make PVC softer, has great influence on the kidney, liver and testis in human body, which will lead to symptoms and kidney damage, destroy the human functional reconstruction system and affect development. Therefore,
it is recommended that you do not buy it.
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.
Because of its light weight, durability and convenient construction, its flexibility is more suitable for use in China. Its main disadvantage is that when it is used as a hot water pipe, the long-term thermal expansion and cold contraction will cause the pipe wall to be misaligned and cause leakage. Many residential areas in Beijing use aluminum-plastic pipes. In Guangdong and Shanghai, where the decoration concept is relatively new, aluminum-plastic pipes have gradually lost their market. At present, aluminum-plastic pipes are still active in the Beijing market. I believe that in the near future, aluminum-plastic pipes in the Beijing market will also face elimination.
PPR pipe: As a new type of water pipe material, PPR pipe has unique advantages. It can be used as both cold water pipe and hot water pipe. Because of its light weight, pressure resistance and corrosion resistance, it is becoming a popular material. At present, there are few
pipes used 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. The interface of PPR pipe adopts
hot-melt technology, and the pipes are completely fused together, so once it is installed and pressed, it will not age and leak like aluminum-plastic pipe for a long time. PPR plastic pipe itself has no toxicity, but with the increase of service time, it has no self-cleaning function and
sterilization function, and PPR plastic material has become a gathering place for secondary pollution of water quality and a breeding ground for bacteria, which seriously threatens human health.
copper tube: copper tube has the advantages of corrosion resistance, sterilization and so on, and it is the first-class product in water pipes. There are two ways to connect copper tubes. Like aluminum-plastic pipes, the copper tube has the problem of aging and water leakage for a long time. Therefore, in Shanghai and other places, most users install copper tubes by welding. Welding means that the joints are welded together by oxygen, so that it can never leak like PPR water pipes. One disadvantage of copper pipes is that they conduct heat quickly, so the hot water pipes produced by famous copper pipe manufacturers are covered with plastic and foaming agent to prevent heat dissipation. Another disadvantage of copper pipes is that they are expensive. Few residential water supply systems are made of copper pipes, so I'm afraid they can only be seen in export apartments and high-end villas. If you plan to change the water pipe and think the copper pipe is good, it is suggested that you must use the welding interface.
stainless steel pipe: stainless steel material is recognized as a healthy material that can be implanted into human body. Water pipes made of stainless steel have been successfully applied in developed countries for many years, and have become the current trend and development direction. Stainless steel materials are safe and non-toxic, and will not < P > cause secondary pollution to the water quality, so as to keep the water pure and sanitary, and the hygiene and safety can be fully guaranteed. Minle stainless steel water pipes and fittings adopt the patented technology of China
to ensure that the thin-walled stainless steel water pipes can withstand the pressure of 1.6Mpa under the condition of careful installation, which is in line with the national industrial stainless steel ... >: >
