How many degrees of high temperature resistance of PVC pipe

In general, PVC pipes have limited high temperature resistance, and their normal operating temperature range is usually between -15 ° C and 60 ° C. That is to say, PVC pipes generally have high temperature resistance around 60 ° C. This is determined by the characteristics of polyvinyl chloride, the main component of PVC pipes. Polyvinyl chloride is a thermoplastic. When the temperature gradually increases, the activity of its molecular chain increases. When the temperature reaches about 60 ° C, the PVC pipe begins to show signs of softening, and the rigidity and hardness of the pipe will decrease. If the temperature continues to rise beyond its tolerance range, the pipe may undergo obvious deformation, such as pipe diameter tapering, bending parts twisting, etc., which seriously affects the normal use of the pipe.

In practical applications, if the PVC pipe is exposed to high temperature for a long time, it will not only cause the pipe to deform, but also accelerate its aging process. High temperature will cause the decomposition of polyvinyl chloride molecules, releasing hydrogen chloride gas, which will destroy the physical and chemical properties of the pipe. For PVC pipes used for drainage, deformation may lead to poor drainage or even blockage; while PVC pipes used for wire threading have reduced performance at high temperatures, which may not effectively protect the wire and increase safety hazards such as leakage and short circuit. For example, under the high temperature weather in Wuhan in summer, some PVC drain pipes laid in the open air without heat insulation treatment will become soft and partially sunken due to long-term exposure to direct sunlight and high temperature, resulting in reduced drainage efficiency and having to be replaced and repaired, increasing maintenance costs and workload.

Therefore, when using PVC pipes, it should be avoided as much as possible in a high temperature environment. In the process of engineering design and installation, environmental temperature factors should be fully considered. For areas that may be exposed to high temperature, such as close to radiators, heating parts of industrial equipment, etc., other pipes with more high temperature resistance should be selected instead of PVC pipes; if the use of PVC pipes cannot be avoided, effective thermal insulation protection measures should be taken, such as wrapping thermal insulation cotton, installing thermal insulation sleeves, etc., to reduce the impact of ambient temperature on pipes, thereby prolonging the service life of PVC pipes and ensuring their stable performance.
