In the current life of people, hoses are used in many places, and pipe materials are an indispensable and important part of industrial production and daily life.
PVC steel wire hose is a material that is often used. Many friends do not understand some advantages of PVC steel wire hose. So, what should be paid attention to in the advantages and installation of PVC steel wire hose?
The PVC steel wire hose adopts the latest PVC reinforced material, which has a good improvement in both compression resistance and hardness, and can replace ordinary rubber pipes, PE pipes and some metal pipes. This product is widely used in chemical, national defense, manufacturing and other industries, and has become one of the most used hose products. There are many classifications of PVC steel wire hoses, and different types are used in different occasions
1. It has good tensile and compressive strength: but its flexibility is not as good as other plastic pipes.
2. Small fluid resistance: The pipe wall of the PVC steel wire hose is very smooth, and the resistance to fluid is very small. Its roughness coefficient is only 0.009. Its water delivery capacity can be increased by 20% compared with cast iron pipes of the same diameter and 40% higher than that of concrete pipes. %.
3. Excellent corrosion resistance and chemical resistance: PVC steel wire hose has excellent acid resistance, alkali resistance and corrosion resistance.
4. Good water tightness: The installation of PVC steel wire hose has good water tightness whether it is connected by bonding or rubber ring.
5. Anti-biting: PVC steel wire hose is not a source of nutrition, so it will not be attacked by rodents. According to tests conducted by the National Sanitation Foundation in Michigan, rats will not bite PVC steel wire hoses.
6. Performance test: curing time shrinkage, splitting strength, tensile strength, peel strength, thermal stability, pot life, storage period, release of harmful substances.
1. When the small-diameter pipe is bonded by solvent, the socket must be rounded to form a groove, and the fracture must be flat and the axis is vertical, so that the bonding can be firm and avoid water leakage.
2. Generally, PVC steel wire hoses with a pipe diameter greater than or equal to 100 mm use rubber ring interfaces. Before installation, personnel must be arranged to chamfer the pipe socket part, and also check whether the quality of the rubber ring is qualified. During installation, the socket, rubber ring, etc. must be wiped clean.
3. The ditch excavation of traditional pipeline installation only requires that the pipeline can be put into the ditch and can be sealed. When the original soil layer is not loosened, it is not necessary to pressurize and compact the cushion.
4. The general wire hose pipe can be split with a tee or a vertical water stop. During construction, a saddle-shaped fitting can be added with half a two-in-one three-way connection and clamped with U-shaped bolts, so as to thicken the pipe wall, then drill holes directly on it, and then connect them with externally threaded plastic parts.
The test shows that the pressure test and acceptance after construction by this method can fully meet the requirements of the specification. In addition, 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.
PVC steel wire hose is the most widely used pipe material in life today, and PVC steel wire hose has remarkable characteristics.
