What kind of water pipes are suitable for outdoor decoration?

It is better to use PPR water pipes when home renovationPPR pipe is an up-and-coming product of UPVC water supply pipe, aluminum-plastic pipe, PE pipe, PE-X pipe and PE-RT pipe. Because it uses random copolymerization technology, the strength and high temperature resistance of polypropylene are well guaranteed, so that it has become the main force of water pipe materials.

PPR water pipe adopts the method of hot welding, with special welding and cutting tools, so it has high reliability, and is also very economical, the insulation performance is also very good, the pipe wall is also very smooth, very suitable for home use.

Benefits of PPR Water Pipes:

1. Health and environmental protection. Polypropylene is an environmentally friendly material that can be used for drinking water transportation.

2. The joints are connected by hot melt to become one, 100% leakage-free, and other materials are connected with wire mouths, which is inferior in impermeability and avoids the toxicity of glue bonding.

3. The conveying resistance is small.

4. Cheap and moderate.

5. Long service life, according to the national standard GB T18742 production and use can be used for 50 years.

When decorating a home, how to choose a water pipe and what kind of suitable one to choose.

From a health point of view, stainless steel water pipes are chosen. As the safest food-grade metal material, stainless steel can naturally form metal cations in the pipe wall, which can effectively prevent the bacterial reproduction of overnight water, thereby reducing the harm of overnight water. The stainless steel drinking water pipe made of stainless steel is not only healthy, but also safe and reliable, strong corrosion resistance, luxurious appearance, long service life, no need to replace maintenance, and save costs.

Stainless steel water pipe, healthy and good water pipe, to prevent the secondary pollution of water in the transmission process, is a good choice for home improvement water pipes. Therefore, let the stainless steel water pipe become the last line of defense for the safety of human drinking water, and why not do it for multiple health protections!

It is better to use Liansu water pipes for outdoor surface-mounted water pipes.

Introduction to the types of plastic water pipes;

1. Galvanized iron pipe, galvanized iron pipe is the most used material at present. At present, China is gradually phasing out this type of pipeline.

2. Copper pipe, a more traditional but more expensive pipe material, durable and convenient to construct.

3. Stainless steel pipe, stainless steel pipe seepage is a more durable pipe material, and the probability of being selected in the decoration project is low.

4. Stainless steel composite pipe, stainless steel composite pipe and aluminum-plastic composite pipe are similar in structure.

There are more outdoor water supply pipe steel pipes, because outdoor laying is more buried and overhead laying, and steel pipes are more suitable, and its compressive resistance and corrosion resistance are relatively good.

There are many kinds of outdoor water supply pipes, and what kind of water supply pipes are used depends on the laying conditions and use requirements and the size of the pipe specifications.

Commonly used water supply pipes are: steel pipes, hard polyvinyl chloride (PVC-U) water supply pipes, polyethylene (PE) water supply pipes, ductile iron water supply pipes, random copolymer polypropylene (PP-R) pipes, reinforced concrete water supply pipes, water supply cast iron pipes and other pipes.

If the working pressure of the pipeline is not high (working pressure p), the outdoor water supply pipe is laid buried, and the polyethylene (PE) water supply pipe is a better choice. If the pipeline is laid overhead, steel pipes are required. If the pressure of the outdoor water supply pipe is high and the working pressure p is p, steel pipe or ductile iron pipe should be used.

The comparison table of water pipe specifications and sizes is shown below.

1. Size: DN15 (4 pipes), DN20 (6 pipes), DN25 (1 inch tube), DN32 (1 inch 2 tubes), DN40 (1 inch half tube), DN50 (2 inch tubes), DN65 (2 inch half tubes), DN80 (3 inch tubes), DN100 (4 inch tubes), DN125 (5 inch tubes), DN150 (6 inch tubes), DN200 (8 inch tubes), DN250 (10 inch tubes), etc.

2. Divide 1 inch into 8 equal parts of 8 inches.

It is equivalent to 1 to 7 points, and the smaller size is represented by 64, and the unit is still inches. If the denominator and the numerator can be reduced (e.g., the numerator is ), they should be reduced.

The indication of inches is to put two apostrophes in the upper right corner, such as 1 2"

For example, the water pipe of DN25 (25mm, the same below) is the imperial system 1"The water pipe, which is also the former 8-point pipe.

The water pipe of DN15 is the imperial system 1 2"The water pipe, which is also the former 4-point water pipe.

For example, the water pipe of DN20 is an imperial 3 4"The water pipe, which is also the former 6-point pipe.

1. The thickness of the wall of the cold and hot water pipes is different, and the cold water pipes cannot be used as hot water pipes, and the easy way to distinguish the cold and hot water pipes is to have a red line mark on the hot water pipe.

2. The newly installed water supply pipeline must be pressurized in accordance with the relevant regulations. The test pressure of the metal and its composite pipe is stabilized for 10 minutes, and the pressure drop in the pipe should not be greater than that, and there is no leakage; The pressure of the plastic pipe should be stabilized for 20 minutes, and the pressure drop in the pipe should not be greater than that, and there should be no leakage.

3. PPR water pipes, steel-plastic water pipes, and copper pipes are commonly used for home decoration water pipes, and the steel-plastic pipes are relatively higher, while the accessories of PPR water pipes are higher than those of steel-plastic pipe fittings, and copper pipes are the most expensive, which is equivalent to about 4 times that of PPR pipes.

4. Home decoration laying water pipes should be avoided from the ground as much as possible, and it is best to line from the top or wall, the amount of pipes may increase slightly, but it is conducive to future pipeline maintenance.

5. Pay attention to the diameter and wall thickness of the water pipe for home decoration, the general general pipe should be in charge with 6 pipes, and the pipes can be selected with 4 pipes, in order to ensure water consumption, the pipes can also use 6 pipes.

6. The standard length of PPR pipes is four meters each, and when you buy it, you should ask clearly whether the merchant is talking about the ** or ** per meter of pipes, and remember to check whether the length of the pipe meets the requirements after the pipe is delivered.

7. When purchasing pipes for home decoration, pay attention to whether the inner diameter of the pipe is symmetrical, and the uneven thickness of the pipe diameter will affect the docking of the two interfaces.

1. PPR water pipe: for such products as Jiankong, its stability is relatively good, even if it is used for a long time in cold and hot hail water, it will not be damaged, and the service life is relatively long, most people will install it in the wall, because it will not crack after construction, so it can be used with confidence.

2. Aluminum-plastic pipe: It is a very malleable pipe, which is relatively simple in construction, but there will be certain limitations in use, if it is only used as a straight water pipe, there will usually be no problem, but if it is used as a curved water pipe, it is prone to cracks, so it should be used with a little attention.

3. Aluminum-plastic composite pipe: From the perspective of reliability, this product is much better than similar products, and it is not easy to crack, and it is relatively simple in construction. In addition, because it is fused with two materials, the characteristics of the entire pipe are effectively improved, and it can be used with more confidence.
