PE管的應用壽命是多久?

我們在接到客戶征詢的時刻常常會有客戶問到如許的成績,鳳山康美塑化有限公司技術人員在這裏做一些解答。

PE管的應用壽命是多種身分決議的,好比原資料,臨盆工藝,應用辦法,情況等。

起首說說原資料,國際的PE原料根本上都可以或許到達抗老化50年,然則因為客戶的需求分歧,所以完整用國標PE料子做PE管材的並非許多,所以,料子有時刻目標略微完善一點,那末反抗老化有必定的影響。其次是臨盆工藝,有些廠家爲了追求高利潤在臨盆上偷工減料,好比壁厚相差超越規模,好比機械設備又不穩固,招致管材外部雜質較多等,如許就影響了PE管自己的承壓才能了。

然後PE管的施工上對管材自己的損壞或許磨擦也會形成必定的影響,管材自己的受損,會下降PE管的應用壽命。

PE管固然是能防腐,然則趕上特殊卑劣的情況也是會對應用壽命形成很大影響的,好比強酸強堿,低溫(大于60°),或許被歷久冰凍等,國標尺度外面管材壽命50年是指在溫度23°的情形下,溫度的變更對PE管材壽命是有必定比例的折減的。

別的還有一些身分會影響PE管的壽命,如運輸,寄存,內部壓力等等,如你在HDPE給水管推銷中有疑問可來電征詢我們!

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!
