Question 2: Which brand of domestic tap water pipe is of good quality? How to choose the material of water pipe during decoration?
The selection and installation of water pipes in "concealed engineering" has become a problem that cannot be ignored in decoration. At the same time, in order to make the room beautiful, people usually 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 for this may come from the following aspects: First, the plastic pipes used are not qualified products. There are some inferior products with poor quality and cutting 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 the plastic pipe is connected with metal at the corner, so the plastic pipe and metal are not welded or threaded, but bonded with special glue. In the case of large temperature difference, such as sudden cooling, the thermal expansion coefficients of plastic and metal are different, and the glue is easy to crack, which leads to the burst of water pipes. Third, plastic water pipes are aging. Because plastic contains "plasticizer", it will escape with the passage of time, causing plastic to become hard and brittle. Sunlight can also age plastics, and ozone in the atmosphere can also damage plastics. Aging plastic pipes are easy to burst under the impact of water pressure and water hammer.
Relevant investigations show that there are mainly galvanized steel pipes, PAP (aluminum-plastic composite pipe), PPR (polypropylene ester composite pipe) and UPVC (polyvinyl chloride composite pipe) on the market at present, as well as some copper pipes and plastic-lined thin-walled stainless steel pipes with good quality and performance. Galvanized steel pipe is not corrosion-resistant and antibacterial, and the inner wall has poor scaling resistance. After long-term contact between water and the inner wall of the pipeline, 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 water after a long time. Therefore, in 2000, the state 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 8 1%, Canada accounting for 85%, Australia accounting for 85%, Britain accounting for 95%, Hong Kong accounting for 70% 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 they are widely used in houses.
Copper pipes have excellent characteristics that other pipes do not have, such as hygiene and health characteristics. Copper can inhibit the growth of bacteria, and 99% of bacteria disappear after entering the copper tube for 5 hours, thus ensuring the cleanliness of drinking water. Moreover, it is durable, safe and maintenance-free for life. However, the price of copper pipes will be slightly higher. For example, to decorate a two-bedroom apartment, it costs about 1 ,000 yuan to use ordinary pipes, while it costs about 1 to use copper pipes with good performance, 300 yuan.
Variety 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 are 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 1 2000, and the use of hot galvanized cast iron pipes will be gradually restricted, and aluminum-plastic composite pipes and plastic pipes will be promoted. Therefore, there are three main types of pipelines currently in use. The first category is metal pipes, such as plastic-lined hot-dip cast iron pipes, steel pipes and stainless steel pipes. The second category is plastic-coated metal pipes, such as plastic-coated 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 be approved by the health department before they can be sold.

Comprehensive performance requirements of water supply pipeline:
As a water supply pipeline, it requires hygiene, safety, energy saving and convenience. Therefore, pipeline inspection should start from four aspects. That is, hygiene: pipes and fittings must be harmless 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 ... >>

As mentioned above, the selection and installation of water pipes in "concealed engineering" has become a problem that cannot be ignored in decoration. At the same time, in order to make the room beautiful, people usually 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 suffered this annoying "trauma" deeply. Keep your eyes open and choose water pipes.
Question 5: What kind of water pipe is good for home improvement? What are the top ten brands of water pipes for house decoration? Most 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 the high cost performance, most families use the former, and the quality of PP-R pipes is more secure and widely used.
Just more expensive. With people's attention to product quality, more and more families and offices now choose PP-R water pipes. Need to pay attention to several aspects, now let's analyze: what kind of water pipe is 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 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.
UPVC pipe: In fact, 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.
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.
PPR pipe: As a new type of water pipe material, PPR pipe has unique advantages. It can be used as a cold water pipe or a 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.
Copper tube: copper tube 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.
Stainless steel pipe: stainless steel material is recognized as a healthy material that can be implanted into human body, and water pipes are all made of 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.

Question 6: Which brand of water pipes is more cost-effective? According to industry insiders, the top ten ppr's are similar except for Liansu. Jinde is of good quality, better used in the north, and people in the north understand the antifreeze! But the price is more expensive. The purchase prices of Rifeng, Cai Zhong and Wei Xing are out of proportion with the sellers! Mainly manufacturers guide the sales model, take our master's market and give higher rebates! Jinniu brand is the most grounded and reasonable, and the rebate is basically a pack of cigarettes! In fact, Jinde, Rifeng, Cai Zhong, Wei Xing and Jinniu will all have problems, but you haven't seen them before. To put it bluntly, China people will decorate a house all their lives! You'd better look at what you want to use, visit more brand stores, ask more about the price, look at the goods and ask more qualified people in the industry. For example, some experts like to use Rifeng, because the rebate is high, making money is right, but the idea is wrong! Don't ask such people.
Question 7: What brand of water pipes are good? Just bought a new house. How to choose the right pipe at the right price is a very important thing for the owner. Now 80% of the problems in home decoration are in water and electricity. The selection and installation of water pipes in concealed engineering has become a problem that cannot be ignored. Once the water pipe leaks and bursts, it will bring irreparable consequences.
It is recommended to use Sorbonne brand water pipe, which is better among similar PPR water pipe brands and has high cost performance. South Korea imported raw materials ~ ~ ~
Question 8: Excuse me, what kind of water pipe is good for decorating the house, and what brand of water pipe is good? Everyone knows that hydropower is a concealed project, so we should pay special attention to the selection of pipe fittings. There are many kinds and brands of water pipes on the market now, which brings a lot of trouble to everyone's purchase. If the selection is not good, such as poor quality, it will be very inconvenient for future maintenance. Then, what kind of water pipe is good for decorating the house and what brand of water pipe is good? I recommend one for you. You can refer to it
At present, this kind of water pipe in the water supply market can be divided into the following categories: one is the most commonly used PPR water pipe at present. There are also aluminum-plastic pipes, PERT pipes, PB pipes, galvanized pipes and even copper pipes. Among them, PPR tube has a relatively large market share and is relatively mainstream. For the quality requirements of PPR pipe, the thickness should not be less than 2.8. Cold water pipe should not be less than 2.3.
At present, if hot and cold water pipes are mixed, hot water pipes are used uniformly.
After the PPR hot water pipe is thickened, it can ensure a kind of stability and is not easy to be damaged in the future cold and heat exchange.
The biggest advantage of PPR pipe is that its pipes and fittings are hot-melted. After hot melting, the pipe and pipe fittings are connected into a whole. This kind of pipeline is directly buried in the ground or in the wall, and the risk in the later stage is almost small. Other pipes, such as aluminum-plastic pipes, are of good quality.
Which pipeline brand is better: 1. Times listed companies, top 500 enterprises in China, top 10 light plastic industries in China, national standard-setting units for plastic pipes, high-tech enterprises and Yonggao shares.
2. Participating units such as national standards for poly plastic pipes, top ten brands of water pipes, environmental label certification, high-tech enterprises, Shanghai famous brands and Ai Kang Enterprise Group (Shanghai) Co., Ltd.
3. Wei Xing started from 1976 and is a listed company. It used to be a famous brand in China, vice chairman of China Plastic Pipe Professional Committee, one of the top ten brands of water pipes, and a subsidiary of Wei Xing Group.
4. Top ten brands of Gu Meier Milgu Pipe Industry, famous brands in Shanghai, domestic large-scale manufacturers of high-quality home improvement pipeline products, large-scale group enterprises, and Jinsu Enterprise Group (Shanghai) Co., Ltd.
5. Piersa Piersa modern high-tech large-scale plastic pipe production comprehensive enterprise, top ten brands of pipes, Jiangsu famous brand products, Jiangsu Piersa Pipe Industry Co., Ltd.
6. Liansu Laisuo is a listed company, a professional manufacturer of large-scale plastic pipes and fittings in China, a leading domestic large-scale building materials and home furnishing industry group, and China Liansu Group Holding Co., Ltd..
7. Cai Zhong was once a famous brand in China, a national high-tech enterprise, one of the largest plastic pipeline manufacturers in China, and a well-known pipeline brand, Zhejiang Cai Zhong Pipeline Technology Co., Ltd.
8. Longsheng Tube LS Shanghai famous brand, building decoration materials/bathroom heating equipment comprehensive group, household hydropower system expert, high-tech enterprise, Shanghai Longsheng Industrial Co., Ltd.
9. Jiumu JOMUGY is one of the top ten brands of pipe industry and a large-scale pipe-making enterprise, which is famous for its excellent quality in the pipe-making industry and recommended by the national engineering construction. Suzhou jiumu pipeline technology co., ltd.
10. Rifeng was awarded as a famous brand in Guangdong Province, China, one of the largest suppliers of new pipelines in the world, and Foshan Rifeng Enterprise Co., Ltd., a leading brand in the new pipeline industry.
So much for the introduction of water pipes. These brands are all good. Personally, I suggest you go to a regular store to buy water pipes, so that not only the quality can be guaranteed, but also the after-sales service can't keep up. Be sure to measure the pressure after the water pipe is installed.
Question 9: Which brand is good for home decoration water pipes? With the development of the times, the materials of water pipes are more and more, and their durability is getting stronger and stronger. Copper core water pipe is one of them. For home decoration, consumers are often confused when purchasing. What brand of water pipes are of better quality? After all, hydropower is a "hidden project", and modern decoration water pipes are built under the wall. If the water pipe leaks and bursts, it will bring irreparable consequences.
