pe双壁波纹管环刚度有几种

近年pe双壁波纹管足足火爆了一把,销售根本停不下来,跟行业相关的人应该清楚这句话的含义。今天来科普一下,pe双壁波纹管环刚度有几种?

In recent years, PE double wall corrugated pipe has been a hot one. Sales can not stop at all. People who are related to the industry should know the meaning of this sentence. Today, what about the rigidity of PE double wall bellows?

Several kinds of stiffness of PE double wall bellows ring


pe双壁波纹管环刚度有几种?就目前市面上来看,主要有两种,4千牛和8千牛,就是大家常说的SN4与SN8级别。它们有什么区别?相信许多人已经知道,我在这里再啰嗦几句。千牛的单位定义的是管道的环刚度,它与承压是成正比的,数字越大,承压能力超强。承压能力与pe双壁波纹管的埋深又成正比。SN4的埋深在1.5米左右,最好不要超过2米。SN8的埋深在2.5米,最多不要没过3米。为什么有这个界限,大家发挥下想象力吧。

What are the stiffness of PE double wall bellows ring? On the market, there are mainly two kinds, 4 thousand cattle and 8 thousand cattle, which is what we often call SN4 and SN8 level. What's the difference between them? I believe many people already know that I am here for a long time.  The definition of the unit is the ring stiffness of the pipe, which is directly proportional to the pressure. The larger the number, the greater the capacity of the pressure. The bearing capacity is directly proportional to the burial depth of the PE double wall corrugated pipe. The buried depth of SN4 is about 1.5 meters, preferably not more than 2 meters. The depth of SN8 is 2.5 meters, not 3 meters at most. Why do we have this limit? Let's play our imagination.

还有一个级别,用的比较少:SN10。pe双壁波纹管厂家生产的少之又少。当pe双壁波纹管达到这个等级时,它所耗费的成本甚至超过了hdpe钢带增强聚乙烯螺旋波纹管。对于工程的甲方和施工方来说是不愿意接受的。但是有时设计院里出图纸的时候如果定性为SN10的话,甲方与施工方只能按部就班的照做了。

There is another level that is less used: SN10. PE double wall bellows manufacturers produce less and less. When the PE double wall bellows reaches this level, it costs more than the HDPE steel belt reinforced polyethylene spiral bellows. It is not acceptable for the first party and the builders of the project. But sometimes when the drawings in the design courtyard are SN10, the first party and the constructor can only follow the instructions.
