Recently, with the increasing demand for spray operation in agriculture, industry and landscape, PVC spray pipe is a common equipment, and its service life has attracted much attention.

In the field of agriculture, PVC spray pipe is often used in crop irrigation and pesticide spraying. If in a mild climate environment, for daily irrigation, and the use of moderate frequency, while being properly maintained, such as regular cleaning of impurities in the tube, to avoid exposure and low temperature freezing injury, the service life of this type of PVC spray tube can reach 5 to 8 years. However, if it is frequently used for high-concentration pesticide spraying, and the pesticide is corrosive, coupled with high temperature exposure in summer and severe cold test in winter, the tube is easy to age and become brittle, and its life may be shortened to 2 to 3 years. For example, in some vegetable growing areas in the south, vegetable farmers frequently use highly corrosive pesticides to spray through PVC spray pipes in order to prevent and control diseases and insect pests. After 2 years of use, the spray pipes have broken and leaked.

In industrial scenarios, PVC spray pipes are mostly used in workshop dust reduction and cooling. In the relatively clean, relatively stable temperature and humidity of the electronic manufacturing workshop, the PVC spray pipe used for dust reduction, due to the good working environment, small interference by external adverse factors, if the installation is reasonable, daily maintenance in place, the service life can reach 8 to 10 years. However, in the chemical workshop, the spray pipe needs to be exposed to all kinds of corrosive gases and liquids. Even if the special PVC spray pipe with chemical corrosion resistance is selected, its life will be greatly reduced. Such as in the electroplating workshop, full of acidic mist, ordinary PVC spray pipe may only be able to maintain 1 to 2 years of normal use, will be due to the corrosion of the pipe wall thinning and scrap.

In terms of landscape fog, the PVC spray pipes in parks and scenic spots mainly create a dreamy atmosphere. In a normal outdoor environment, if the installation location is reasonable, to avoid human stampede, mechanical collision, and regular inspection and maintenance of the pipe body, its service life is usually 5 to 7 years. However, if it is located in a coastal area with high salt spray, salt spray will accelerate the corrosion of the pipe body, or if it is installed in an area with frequent tourist activities, it is easy to be damaged by external forces, and the service life may be reduced to 3 to 5 years. Like the spray landscape facilities of some seaside parks, due to long-term sea breeze erosion, PVC spray pipes have been damaged to varying degrees after 3 years of use.

The service life of PVC spray pipe is not fixed for a long time, and is affected by various factors such as the use environment, application scenarios, and maintenance. Users should choose reasonably, use correctly and maintain carefully according to the actual situation, so as to prolong its service life and ensure the stable operation of spray operation.
