Can PE pipes really be used for 50 years

Can PE pipes really be used for 50 years
This is a problem that many people are concerned about. In fact, this 50 years is only a theoretical time. It is derived from a series of testing methods and formulas according to ISO standards. Temperature, pressure and service life are a function relationship. According to the relevant national standards, the pipe life is generally not less than 50 years under the design conditions that meet the standards. However, improper production, storage and harsh environment will reduce the life of PE pipes. The service life of PE pipes is determined by many factors, so what factors affect the service life of PE pipes?
The first is raw materials. The domestic top PE raw materials can basically achieve 50 years of anti-aging. However, if the raw material indicators are slightly lacking, anti-aging will have a certain impact. And in the process of production process, some manufacturers cut corners in production in order to seek high profits, such as the wall thickness difference is out of range, the instability of mechanical equipment, resulting in more impurities in the pipe, etc. In this case, the pressure bearing capacity of PE pipe itself will be affected, and its service life will be affected.
Secondly, PE pipe will also cause damage to the pipe itself during construction, and friction will also have a certain impact, causing damage to the pipe itself and reducing the service life of PE pipe.
The last is the impact of the environment. Although PE pipes have corrosion resistance, they will also have a great impact on the service life in particularly harsh environment, such as strong acid and alkali, high temperature, or long-term freezing. The service life of PE pipes in the national standard is 50 years, which means that the temperature is 23 °, so the change of temperature also has a certain proportion of reduction on the service life of PE pipes.
In addition, there are some factors that will affect the service life of PE pipes, such as transportation, storage, external pressure, etc.
Once PE pipes abuse recycled materials, mix ingredients, or do not strictly control production, it will accelerate the aging rate of pipes and reduce the service life of pipes. Even if there is no exposure problem at the beginning of installation, the performance of the pipeline will rapidly decay.
The polyethylene pipes and pipe fittings used for water supply and drainage of Midier are made of high-density polyethylene as the main raw material and are produced with advanced equipment, with excellent impact resistance; Good low temperature resistance, low temperature embrittlement temperature can reach - 70 ℃; Good chemical stability, resistant to all kinds of acid, alkali and salt corrosion; Good toughness, torsion resistance, earthquake resistance, etc. Anhui Meidiyuan Water-saving Technology Co., Ltd., guided by scientific and technological innovation and guided by the development goal of "integrity, innovation and development", has won a broad market and a good reputation for its high-quality brand and good service.
