Insulating tubing, insulated heat-shrinkable tubing generally need to be classified by voltage, that is, to know the power level of the insulated body and the highest tool voltage that the heat shrinkable tubing can withstand, generally 1KV, 10KV, 20KV, 35KV, etc. And so on, in general, the relationship between the pressure resistance of the heat-shrinkable sleeve and its thickness is related to the material of the formula. In certain circumstances, the thickness is the main parameter, but sometimes the thickness of the heat-shrinkable tube is not required. Insulation is to strengthen the sheathing effect.
The traditional water supply pipe network is mainly based on traditional materials such as steel pipes, cast iron pipes, and concrete pipes. Since the middle of the 20th century, plastic pipes have been widely used in place of traditional pipes in the world, and plastic pipes have maintained a high growth rate, among which the Asia-Pacific region The pipe market will grow fastest in the future.
Insulation tubing is widely used in the fields of urban water supply and drainage, construction water supply and drainage, hot water supply, and heating heating. One of the most important application areas is the water supply network, which is the second largest area for drinking water management. Among the many pipe varieties, the use of PVC pipe has an absolute advantage, but in recent years, the practice of pipe applications in developed countries shows that, regardless of whether the water supply pipe or the drainage pipe, the development speed of polyolefin pipe greatly exceeds the development of PVC pipe. . It can be expected that polyolefins, especially polyethylene pipes, will gradually dominate.
At present, China has formed a series of insulating pipe, including agricultural pipe, construction of hot and cold water PP pipe, and so on, some companies are currently developing special materials for buried drains. However, it should be noted that at present, there is a general lack of research on the processing performance of pipe materials in China, which leads to imperfect technical services and further research and development of domestic pipe materials. This will also affect the healthy and rapid development of the entire pipe industry in China.
