Is PE pipe resistant to high temperature?

In the field of modern plumbing and municipal construction, PE pipe has been widely used for its excellent corrosion resistance, flexibility and construction convenience. However, many users will be concerned about an important question when choosing PE pipe: Is PE pipe resistant to high temperature? This is directly related to the safe and stable operation of the pipeline system in different environments.

PE pipe, that is, polyethylene pipe, its main raw material polyethylene is a high crystallinity, non-polar thermoplastic resin. From the perspective of material characteristics, the high temperature resistance of ordinary PE pipe does have certain limitations. Generally speaking, the recommended temperature range of PE pipe is between -20 ° C and 40 ° C. When the operating ambient temperature exceeds this range, especially when it is at a higher temperature for a long time, the physical and mechanical properties of PE pipes may be affected, such as softening, strength reduction, creep increase, etc., which affects the service life and safety of the pipeline. This is because the polyethylene molecular chain is prone to thermal oxidative aging at high temperatures, and the intermolecular force is weakened, resulting in the deterioration of pipe performance.

So, does it mean that PE pipes cannot be applied at all in high temperature environments? The answer is no. With the continuous advancement of technology, the high temperature resistance of PE pipes can be significantly improved through material modification, process optimization and other means. For example, the use of special formulations, such as the addition of antioxidants, ultraviolet absorbers, and the use of polyethylene raw materials with more reasonable molecular weight distribution, can improve the thermal oxygen aging performance of PE pipes.

It is understood that AD Pipe always pays attention to the optimization and improvement of material properties in the research and development and production of PE pipes. According to the needs of different application scenarios, AD Pipe will make corresponding performance adjustments to PE pipes. For PE pipes that need to be used in higher temperature environments, AD Pipe will pass strict raw material screening and advanced production process control to ensure that the product can still maintain good structural stability and mechanical properties within a certain high temperature range. For example, in some industrial drainage, ground source heat pumps and other fields that have certain requirements for temperature, specially treated AD PE pipes can meet their specific high temperature resistance needs.

Of course, even if the PE pipe has undergone an improvement in high temperature resistance, in practical applications, it is still necessary to comprehensively consider and select according to the specific operating temperature, medium characteristics and pressure factors. If it is in an extreme environment where the temperature is too high (such as long-term exceeding 60 ° C), it may be necessary to consider other pipes with more high temperature resistance, such as PPR pipes, steel pipes, etc. Therefore, when choosing PE pipes, it is recommended to consult a professional pipeline technician or refer to the product technical manual provided by AD Pipe to ensure that the selected pipe fully meets the requirements of actual working conditions.

In summary, the high temperature resistance of ordinary PE pipe has its inherent range, but it can be improved through technical means. AD Pipe is committed to providing high-quality and high-performance PE pipe products to meet the application needs of different users in various complex environments. When selecting PE pipe, fully understand its high temperature resistance characteristics and combine it with actual use conditions to ensure the safe, efficient and long-term operation of the pipeline system.
