In the decoration, waterproofing is often more important than any topic. What precautions should be taken when installing and using stainless steel tubes?
First, the installation of stainless steel water tank must find a professional mechanic. No matter how luxurious and upscale you decorate, if you are not willing to spend money on this aspect, it will not be worthwhile. Often the cracks or leaks in the pipeline will cause the water pipe itself to be tens, hundreds, or even thousands of times more expensive.
Second, after the device must be pressurized test. The pressurization test is generally carried out under 1.5 times the water pressure, and there should be no water leakage during the test.
Home stainless steel tube:
Third, no pressure test method:
1. Close the main valve of the water pipe. The water meter switch in front of the water meter)
2. Open the faucet inside the room for 20 minutes to ensure that no water is dripped and then close all taps.
3, close the toilet tank and washing machine with water storage device water inlet switch.
4, open the main valve of the water pipe.
5. Check whether the water meter is moving 20 minutes after opening the main valve, including slow walking. If there is movement, it will be leaking. If it does not move, it is all right.
Fourth, in daily use, if you find the following conditions, check the relevant pipeline as soon as possible:
1, the wall paint appearance moldy bubble.
2, baseboard or wood floor black and appearance of fine bubbles.
How to choose the decoration hose?
How to choose the decoration pipe Building materials city you will find, but the dazzling plumbing, PP-R pipe, PVC-U pipe, lined steel pipe, stainless steel pipe, brass and other varieties. The term "safe endurance" means that no water leakage, burst or other events that endanger life and family safety occur during the service life of the water pipe, and it can ensure long-term use. Building Materials City, you will find a wide range of water pipes, such as PP-R pipe, PVC-U pipe, plastic-lined steel pipe, stainless steel pipe, copper pipe and so on.
The water pipe should be stable, reliable, watertight, and non-explosive.
The term "safe endurance" means that no water leakage, burst or other events that endanger life and family safety occur during the service life of the water pipe, and it can ensure long-term use.
This requires the water pipe to be resistant to corrosion, high temperature, frost resistance and good mechanical properties. The comparison found that plastic pipe can not be high temperature resistance, deformation is likely to cause leakage under a large temperature difference, and its small pressure resistance, easy to embrittlement, these are destined to not be suitable for long-term heating, not suitable for use in the cold south, Not suitable for high-rise buildings.
Composite pipe combines the advantages of metal pipe and plastic pipe, but precisely because of the different expansion coefficients of plastic and metal, temporary use will inevitably lead to delamination of the pipe, causing harm.
For copper pipes, copper is known to have a low order in chemical activity ranking, stable performance, and strong corrosion resistance. Copper is a material with a certain strength in the metal and excellent plasticity and toughness, and has excellent low temperature performance. Therefore, the copper water pipe is not only resistant to heat and fire, but also has no anti-frost performance. The copper pipes installed from the Peking Union Medical College Hospital in the 1920s have undergone more than 80 years of vicissitudes, and they are still performing well. This shows that the copper pipes can be durable and have temporary safety and reliability equivalent to those of buildings. In addition, the copper tube is robust and has a low thermal expansion rate and is particularly suitable for embedding in cement walls without fear of wall cracking. However, 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 infiltrate. Especially if they are used in direct drinking water supply systems, they have serious harm to the human body. Another example is the long-unwanted water pipe that unexpectedly opened out and found yellow water flowing out. In previous galvanized steel pipes in residential areas, such a thing could easily happen. This kind of yellow water is also harmful to the human body and the copper material pipes can inhibit the growth of bacteria. E. coli can no longer reproduce in the copper pipeline. More than 99% of E. coli and pneumococcal bacteria eliminated itself after entering the copper pipeline for 5 hours, and adhered to the cleanliness of drinking water.
PP-R and copper pipes can be buried in walls.
As we all know, plastic pipes are extremely convenient to install, and they are selected for drainage pipes. However, most of the components connected to them are metal parts. Because the mechanical properties of plastics and metals are very different, it is easy to cause burst or water leakage. Generally cannot be buried in a wall, but can only be laid outside. PP-R and copper pipes and their accessories are complete in variety and specifications and can be selected from 6mm to 250mm. The PP-R pipe can be seamlessly welded. The manufacturer can also bury the wall when installing the device. The advantage is that the price is cheaper and the construction is convenient. The cutting, bending and processing welding of copper tubes are also simple, and the connection forms are various. There are brazing, clamping, crimping, inserting, flanges, grooves, etc., which can completely satisfy various places and situations. Need to buy water pipes, remember to buy, three-character classics, home decoration, people mostly focus on indoor layout and decoration, but as a blood channel at home but little attention. With the media's thinking about poisoning PP pipes, the hygienic properties of household water pipes have received unprecedented attention. How do you choose a reliable water pipe in the face of numerous good and bad pipes on the market? Three-character scriptures."
In home decoration, people mostly focus on indoor layout and decoration, but they do not pay much attention to the “blood” pipeline at home. With the media's thinking about poisoning PP pipes, the hygienic properties of household water pipes have received unprecedented attention. How do you choose a reliable water pipe in the face of numerous good and bad pipes on the market? The three-character passage "Whether the water quality is good or bad, the pipe is important, the water quality is good, and the key is the pipeline. Conservative galvanized pipes are apt to rust, corrosion, and easy to scale. They are prone to microbial growth, cause secondary pollution, and threaten human health. There is often such an experience that no one in the family has opened the tap for a few days, and the lack of gas makes me pay attention to the industry of PE pipe. Yellowish rust flows out, which is the best example of pipe pollution. At present, household drinking water pipelines mainly consist of aluminum-plastic pipes and PP-R pipes. Due to their corrosion-resistant and non-fouling characteristics, they are widely used in drinking water pipelines, but due to the fact that plastics are easy to dope and make false, especially the toxic events of individual PPR pipes are exposed. To remind everyone in the purchase of pipe, the performance of various types of water pipes, quality, brand identification of the last one can not be less.
There is a choice of water pipes:
Healthy water, starting from the tube, how to buy a healthy, safe and durable water pipe, experts will teach you a trick:
A smell: smell the water pipe has no smell. There are many pungent odors in the smuggled toxic plastics.
Second, look at the color, thickness, and glossiness of the pipe. If the outside wall of the pipe is marked with the trademark, specifications, temperature, pressure, production lot number, date of production, and actual origin, the aluminum plastic pipe depends on the thickness and evenness of the aluminum layer. See if there is a health permit. Water pipes without a health permit cannot be used for drinking water pipes.
Third, pay attention to: First, we must pay attention to the formal agent authorized dealership store book sales; Second, we must pay attention to the purchase of pipe, pipe fittings is the same manufacturer; Third, pay attention to request product service card.
