company news about Why do plastic pipes need to be tested?

Plastic pipes exist in every building, every street, and permeate the daily life of millions of households. Why spend so many people's time and energy on seemingly insignificant plastic pipes?

Have you imagined the use environment of pipelines?

If it is exposed to the outside, it may be subjected to scorching sun, heavy rain or even freezing disasters; if it is buried in the wall, the inferior pipe may be ignited by the aging wires around it, while the indoor water supply pipe, through which high-temperature liquid flows, may be softened, deformed, and high-pressure Water rushes out and may cause pipe damage and explosion.

According to well-known pipeline researchers, pipelines need to have various properties such as heat resistance, weather resistance, pressure resistance, oxidation resistance, flame retardancy, and material insoluble in water. In order to detect whether the pipeline is suitable for various environmental requirements and ensure the safety and convenience of users.

Testing items for plastic pipes
