pvc steel wire hose advantages and construction matterspvc steel wire hose—pvc steel wire hose advantages and construction matters
In the current people's lives, many places will use decoration items, in the decoration of piping materials is an indispensable important part. PVC wire hose is a material that is often used. Many friends do not understand some advantages of PVC wire hose. So, what should be paid attention to the advantages and installation of PVC wire hose? The following article specifically introduces to friends.

PVC (full name Polyvinylchlorid), the main component is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is the back coating adhesive. PVC (full name Polyvinylchlorid) is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness and ductility. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is the back coating adhesive. It is a kind of synthetic material that is well-loved, popular and widely used in the world today. Its global usage ranks second among various synthetic materials. According to statistics, in 1995 alone, PVC production in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, the production and consumption of PVC averages 1.4 million tons.

1. It has good tensile and compressive strength: but its flexibility is not as good as other plastic pipes.
2. Small fluid resistance: the wall of PVC-U pipe is very smooth, the resistance to fluid is very small, its roughness coefficient is only 0.009, and its water delivery capacity can be increased by 20% compared with cast iron pipes of the same diameter and increased by 40 compared with concrete pipes. %.
3. Excellent corrosion resistance and chemical resistance: PVC-U pipe has excellent acid resistance, alkali resistance, corrosion resistance, is not affected by moisture and soil pH, and no anti-corrosion treatment is required when laying pipes.
4. Good watertightness: The installation of PVC-U pipes has good watertightness no matter whether it is adhesive or rubber ring connection.
5. Anti-bite: PVC-U tube is not a source of nutrition, so it will not be eroded by rodents. According to tests conducted by the US National Health Foundation in Michigan, mice will not bite on PVC-U tubing.
6. Performance test: curing time, shrinkage rate, split strength, tensile properties, peel strength, thermal stability, pot life, storage period, release of harmful substances.
pvc steel wire hose—Precautions for construction of pvc steel wire hose
1. When solvent bonding is used for small-diameter pipes, the socket must be rounded to form a groove, and the fracture must be flat and vertical, so that the bonding can be firm and avoid water leakage.
2. Generally, PVC pipes with a diameter greater than or equal to 100 mm use aprons. Before installation, personnel must be arranged to chamfer the socket of the pipe, and the quality of the aprons must be checked. The socket, rubber ring, etc. must be wiped clean during installation.
3. The excavation of the pipe trench installed in the traditional pipeline only requires that the pipe can be placed in the pipe trench and can be sealed. When the original soil layer is not loosened, it is not necessary to compress the tamping cushion.
4. General PVC pipe branch pipe can be split with tee or vertical stopcock. During the construction, a saddle-shaped fitting can be added and a half two-in-one tee can be fastened with a U-shaped bolt, so that the wall of the pipe is thickened, and then the teeth are drilled directly on the top, and then connected with an external thread plastic part. The test shows that the pressure test and acceptance after construction with this method can fully meet the specifications. In addition, thrust thrust piers should be installed at the positions where the water flow in the pipe generates thrust, such as elbows, tees and pipe end sealing plates, to withstand the thrust of the water flow.
5. As a new type of non-metallic pipe, PVC pipe can not detect its specific location with the existing metal pipe detection equipment, but if the pipeline burial facility is buried during the work, a wire can be easily solved.
PVC steel wire hose is the most widely used pipe material in life today. PVC steel wire hose has remarkable characteristics. The above also introduces some advantages of PVC steel wire hose and matters needing attention during construction. Interested friends can collect this article, and then study, I believe friends will have satisfactory answers.
