In industrial production and daily life, PVC high-pressure pipe is widely used because of its excellent performance. However, in order to give full play to its role, it is very important to select the suitable PVC high-pressure pipe according to the actual use environment.

In the industrial field, chemical production scenarios, pipelines need to transport all kinds of corrosive media. At this time, to choose the chemical stability of good PVC high-pressure pipe, its material can resist the erosion of specific chemical substances, to ensure the long-term stable operation of the pipeline, to prevent leakage and other security risks. For example, conveying acidic or alkaline liquids, PVC high-pressure pipes containing special additives can meet the needs. Like in the electroplating workshop, it is necessary to transport strong acid and alkali solution for metal surface treatment, and PVC high-pressure pipes with strong corrosion resistance are indispensable.

In terms of building construction, PVC high-pressure pipes will be used in the water supply, drainage and fire protection systems of the construction site. When supplying water, pipes with appropriate pressure resistance grade shall be selected according to the pump pressure and floor height to ensure stable water supply. Drainage needs to consider the impact resistance and wear resistance of the pipeline, and deal with the collision and friction that may be caused by building materials and construction waste. For example, high-rise residential construction, due to the high water pressure, to use high pressure PVC high-pressure pipe; and in the basement and other areas prone to water, drainage with PVC high-pressure pipe should have good impact resistance.

In agricultural irrigation scenarios, PVC high-pressure pipes are used in farmland irrigation systems, and the effects of ambient temperature and ultraviolet radiation should be considered. In high temperature areas, the pipeline should be resistant to high temperature to avoid deformation caused by high temperature in summer; at the same time, for long-term outdoor use, PVC high-pressure pipe with UV resistance should be selected to extend the service life. For example, in large-scale farmland irrigation projects in hot areas of southern China, PVC high-pressure pipes with UV resistance and high temperature resistance have been widely used.

Family decoration, kitchen, bathroom water supply and drainage pipes to choose PVC high-pressure pipe, to pay attention to the size of adaptation and connection convenience. The pipe diameter should be matched with the inlet and outlet of household water appliances, and the connection method should be convenient for installation and later maintenance. For example, the drainage pipe under the kitchen sink, the selection of suitable pipe diameter, the use of simple connection of PVC high-pressure pipe, easy to install and replace.

When choosing PVC high pressure pipe, we should also pay attention to its physical properties. In terms of working pressure, the pressure resistance value of the selected pipeline should be higher than the actual working pressure, leaving a safety margin. For example, the actual working pressure is 0.8MPa, and it is recommended to choose a PVC high-pressure pipe with a pressure resistance of 1.0MPa or higher. Ambient temperature is also very critical, different temperatures, the performance of PVC high pressure pipe will change, high temperature may become soft, low temperature may become brittle, according to the use of ambient temperature range to choose the product. In addition, the wear resistance and flexibility of the pipeline should also be considered in combination with the actual use scenario. For example, in the pipeline system with granular material flow, the wear-resistant PVC high-pressure pipe should be selected; in the place where bending installation is required, the product with good flexibility should be selected.
