In decoration, waterproofing is often more important than any other topic. What should you pay attention to during the installation and use of stainless steel pipes?
First, the equipment stainless steel water tank must find professional technicians. No matter how luxurious and upscale you are, if you are not willing to use money in this area, it will not cost a lot of cracks or leaks in the pipeline, which will cause the water pipe itself to lose dozens of times, hundreds of times, or even thousands of times.
Second, the pump must be tested after the device. The pressurization test is generally carried out with 1.5 times the water pressure, and there should be no water leakage during the test.
Household stainless steel tube:
Third, the test method without pressure:
1. Close the main valve of the water pipe. That is, the water pipe switch in front of the water meter)
2. Open the faucet in the room for 20 minutes, and make sure that all the faucets are closed after no water drops.
3. Turn off the water inlet switch of the water tank function such as the toilet tank and the washing machine.
4. Open the main valve of the water pipe.
5. Check the water meter for 20 minutes after opening the main valve, including slow movement. If there is walking, it is a leak. If it is not moving, it is fine.
4. In daily use, if the following conditions are found, check the relevant pipeline as soon as possible:
1. The surface of the wall paint is mildewed and foamed.
2, the baseboard or the wooden floor is black and the appearance is fine.
How to choose a renovated water pipe?
How to choose the building materials city, you will find that the water pipes are dazzling, PP-R pipe, PVC-U pipe, plastic-lined steel pipe, stainless steel pipe, copper pipe and so on. The term "safety durability" refers to the occurrence of life-threatening and family-safe events such as water leakage, bursting, etc. during the service life of the water pipe, and can ensure long-lasting use. Building materials city, you will find that the water pipes are dazzling, PP-R pipe, PVC-U pipe, plastic-lined steel pipe, stainless steel pipe, copper pipe and so on.
The water pipe should be stable and reliable, watertight and burst free.
The term "safety durability" refers to the occurrence of life-threatening and family-safe events such as water leakage, bursting, etc. during the service life of the water pipe, and can ensure long-lasting use.
This requires the water pipe to be corrosion resistant, high temperature resistant, frost resistant and has good mechanical properties. It is found that the plastic pipe can not withstand high temperature, and the deformation is easy to cause leakage when the temperature difference is large, and the pressure resistance is small and easy to be brittle. These are destined to be unsuitable for long-term heating, and should not be used in the cold south. Not suitable for high-rise buildings.
Composite pipe combines the advantages of metal pipe and plastic pipe, but it is precisely because of the different expansion coefficients of plastic and metal that temporary use will lead to stratification of the pipe and cause damage.
For copper tubes, it is known that copper has a low order in chemical activity sequencing, stable performance and strong corrosion resistance. Copper is a kind of material with certain strength and plasticity and toughness in metal. It has excellent low temperature performance. Therefore, copper water pipe can resist heat and fire, not aging, and has certain frost heaving resistance. The copper pipes installed in Peking Union Medical College Hospital in the 1920s have experienced vicissitudes for more than 80 years, and still have good performance, indicating that copper pipes can be durable and have temporary safety reliability equivalent to that of buildings. In addition, the copper tube is durable and has a low coefficient of thermal expansion, making it particularly suitable for embedding in concrete walls without fear of wall cracking. But the price of copper pipes is more expensive.
Copper tubes can inhibit the growth of bacteria.
The main components of plastic pipes are some high-molecular polymers, which have certain toxicity and are relatively easy to penetrate. Especially in the direct drinking water supply system, it is seriously harmful to the human body. Another example is that the water pipe that has not been used for a long time suddenly opens and discovers the yellow water flowing out. This is the case in the galvanized iron pipe in the house. This kind of yellow water is harmful to the human body. The copper water pipe can inhibit the growth of bacteria. E. coli can no longer continue to reproduce in copper pipelines. More than 99% of E. coli and pneumonia bacteria disappeared after entering the copper pipeline for 5 hours, insisting on the cleanliness of drinking water.
PP-R and copper tubes can be buried in the wall.
It is known that the plastic pipe is very convenient to install, and several measures are selected for the drain pipe, but most of the components connected to it are metal parts. Because the mechanical properties of plastic and metal are very different, it is easy to cause burst or water leakage, so construction Generally, it cannot be buried in the wall and can only be laid outside. The PP-R and copper pipes and their accessories are available in a variety of sizes and specifications, and can be selected from 6mm 250mm. PP-R pipe can be seamlessly welded, and the manufacturer can also be buried in the wall when it is responsible for the device. The advantage is that the price is cheaper and the construction is convenient. The cutting, bending, processing and welding of copper tubes are also simple, and the connection forms are various, including brazing, ferrules, crimping, plugging, flanges, grooves, etc., which can fully satisfy various places and situations. Need to buy water pipes, remember to buy, three characters, home decoration, most people will focus on indoor layout and decoration, but as a home blood pipeline but rarely pay attention. With the media thinking about the poisoning of PP pipes, the hygiene of household water pipes has received unprecedented attention. In the face of many different pipes on the market, how to choose a safe water pipe? Three-character scriptures.
For home decoration, most people focus on indoor layout and decoration, but they are rarely valued as a "blood" pipeline at home. With the media thinking about the poisoning of PP pipes, the hygiene of household water pipes has received unprecedented attention. In the face of many different pipes on the market, how to choose a safe water pipe? The three-character "water quality is good or bad, the tube is important, the water quality is good, the key is to look at the pipeline. The conservative galvanized pipe is easy to rust, easy to corrode, easy to scale, easy to breed microorganisms, secondary pollution, and threaten human health. Often there is such an experience, no one in the house for a few days, open the faucet, --- the lack of gas makes me pay attention to the PE pipeline industry. The yellow rust is flowing out, which is the best example of the water quality of the pipe. At present, household drinking water pipelines mainly include aluminum-plastic pipes and PP-R pipes. Because of their corrosion-resistant and non-fouling characteristics, they are widely used in drinking water pipes, but they are easily doped due to plastics, especially for exposure of individual PPR pipes. Remind everyone that when purchasing pipes, the performance, quality and branding of various water pipes should not be less.
There is a decision to choose a water pipe:
Healthy water, starting from the tube, how to choose a healthy, safe and durable water pipe, experts teach you a trick:
A smell: smelling the water pipe has no smell. Parallel pipes are often mixed with recycled toxic plastics, which often smell pungent.
Second look: look at the color, thickness, gloss of the water pipe, whether the outer wall of the pipe indicates the trademark, specification, temperature, pressure, production batch number, date of production and actual place of production, aluminum plastic pipe also depends on the thickness and uniformity of the aluminum layer, See if there is a health permit. Water pipes without a hygienic permit cannot be used for drinking water pipes.
Three notes: First, we must pay attention to the formal agent store that has the pipe authorized distribution book; second, we must pay attention to whether the purchased pipe and fittings are produced by the same manufacturer; third, we must pay attention to the product service card.
