PE管的使用寿命是多久?

我们在接到客户咨询的时候经常会有客户问到这样的问题,杭州康美塑化有限公司技术人员在这里做一些解答。

PE管的使用寿命是多种因素决定的,比如原材料,生产工艺,使用方法,环境等。

首先说说原材料,国内的PE原料基本上都能够达到抗老化50年,但是由于客户的需求不同,所以完全用国标PE料子做PE管材的并不是很多,所以,料子有时候指标稍微欠缺一点,那么对抗老化有一定的影响。其次是生产工艺,有些厂家为了谋求高利润在生产上偷工减料,比如壁厚相差超出范围,比如机械设备又不稳定,导致管材内部杂质较多等,这样就影响了PE管本身的承压能力了。

然后PE管的施工上对管材本身的破坏或者摩擦也会造成一定的影响,管材本身的受损,会降低PE管的使用寿命。

PE管虽然是能防腐,但是遇上特别恶劣的环境也是会对使用寿命造成很大影响的,比如强酸强碱,高温(大于60°),或者被长期冰冻等,国标标准里面管材寿命50年是指在温度23°的情况下,温度的变化对PE管材寿命是有一定比例的折减的。

另外还有一些因素会影响PE管的寿命,如运输,存放,外部压力等等,如你在HDPE给水管采购中有疑问可来电咨询我们!

What is the service life of PE pipe?

When we receive customer consultation, we often have customers ask such questions. The technicians of Hangzhou Kangmei Plastic Co., Ltd. are here to answer them.

The service life of PE pipe is determined by many factors, such as raw materials, production process, use method, environment, etc.

First of all, speaking of raw materials, the top domestic PE raw materials basically can achieve anti-aging for 50 years, but due to the different needs of customers, so it is not a lot to make PE pipes entirely with national standard PE material. Therefore, sometimes the material is slightly deficient, so it has certain effect on aging. Secondly, the production process. In order to seek high profits, some manufacturers cut corners on production, such as the difference of wall thickness is out of range, for example, the mechanical equipment is unstable, resulting in more impurities in the pipe, which affects the pressure bearing capacity of the PE pipe itself.

Then, the construction of PE pipe will also have a certain impact on the damage or friction of the pipe itself. The damage of the pipe itself will reduce the service life of PE pipe.

Although PE pipe can be anticorrosive, it will also have a great impact on its service life in case of particularly bad environment, such as strong acid and alkali, high temperature (more than 60 °), or long-term freezing, etc. in the national standard, the pipe service life of 50 years refers to a certain proportion of reduction in the life of PE pipe due to the change of temperature under the condition of 23 °.

In addition, there are some factors that will affect the life of PE pipes, such as transportation, storage, external pressure and so on. If you have any questions about HDPE water supply pipe procurement, please call us!
