In recent years, with the rapid development of China's economy, plastic pipes have been widely used. They are mainly used for urban water supply, drainage, building water supply and drainage. Rigid polyvinyl chloride water supply pipe has the characteristics of light weight, high density, good compressive strength, low price, high investment efficiency, energy saving and environmental protection, long service life, good sanitary conditions and convenient installation. However, there are many brands of pipelines with uneven quality. Some pipes marked "good grade" on the surface are actually slightly pulled and ruptured when struck, resulting in low tensile strength. This is conducive to the survival of the fittest in the PVC-U pipe industry. In the following article, we briefly introduce the functions and advantages of PVC pipe coupling, hoping to let you know more about the pipe of this material.
✉ What is a PVC-U pipe
✉ Advantages of pipe
✉ The role of PVC-U piep
✉ In conclusion
PVC-U pipeline is made of sanitary grade polyvinyl chloride (PVC) resin as the main raw material. Through plastic extruder and injection moulding machine, appropriate stabilizers, lubricants, fillers, color reagents are added. After cooling, curing, solidification, inspection, packaging and other processes, the production of pipelines and fittings is completed. It plays an important role in repairing damaged PVC-U pipeline.
Compared with other pipes, PVC-U pipes have the following more prominent characteristics:
1. It has better tensile and compressive strength.
2. Low fluid resistance
PVC-U pipe wall is very smooth and fluid resistance is very small. Its roughness coefficient is only 0.009. Compared with cast iron pipes of the same diameter, the water delivery capacity of them increased by 20% and 40% respectively.
3. Excellent corrosion resistance and corrosion resistance
It has excellent acid resistance, alkali resistance, corrosion resistance, not affected by soil and water acidity, and no anti-corrosion treatment for pipeline laying.
4. Good water tightness
PVC-U pipeline installation, whether using adhesive or rubber ring connection, has good water tightness.
5. Take a bite
It is not a nutrient source, so it will not be eroded by rodents. According to the Michigan National Health Foundation, mice don't bite PVC-U tubes.
They are mainly made of sanitary grade polyvinyl chloride (PVC) resin. Extrude with plastic extruder and inject appropriate amount of stabilizer, lubricant, filler and colorant into injection machine. The main uses of PVC-U water supply pipes are cooling, curing, solidification, testing and packaging.
1. Indoor water supply and reclaimed water system in civil and industrial buildings;
2. Buried water supply system in residential and factory areas;
3. Urban water supply pipeline system;
4. Water treatment pipeline system of water treatment plant;
5. Marine culture;
6. Landscape irrigation, caisson and other industrial pipelines.
They have many characteristics that other water supply pipes do not have. Its corrosion resistance, no scaling, can inhibit the growth of bacteria, effectively prevent secondary pollution of pipelines. If the flexible socket with rubber ring is used at the joint of the pipeline, its vibration resistance and sealing performance are better, and the leakage of the pipeline can be effectively prevented. Using this kind of pipeline in water supply project can not only facilitate construction and reduce construction costs, but also help to ensure water quality, save operation costs and reduce production costs. Therefore, PVC-U pipes will be more widely used in water supply projects. If you want to know more about PVC-U pipe, please consult in time. And we will provide you with the best products.
