不知道大家注意到没有,现在路上的井盖慢慢的发生了变化,球墨铸铁材料的井盖越来越常见!为什么现在大家都选用球墨铸铁井盖呢?这种井盖有什么优点呢?下面山东球墨铸铁井盖厂家的小编就给大家详细的介绍一下!

I don't know if you have noticed that the covers on the road have changed slowly. Ductile iron covers are becoming more and more common. Why do we all use ductile iron covers now? What are the advantages of this kind of cover? Next Shandong Ductile Iron Well Cover Manufacturer's small edition will give you a detailed introduction!

球墨铸铁井盖之所以得到普及,是因为它有一个很重要的优点,就是由于球墨铸铁强度高、韧性好,使得球墨铸井盖要比同类型的灰口铸铁井盖轻百分之三十左右。

Ductile cast iron well cover is popular because it has a very important advantage, that is, because of its high strength and good toughness, the ductile cast iron well cover is about 30% lighter than the same type of grey cast iron well cover.

除此以外,球墨铸铁井盖的以下特点也是他备受推崇的重要原因:

In addition, the following characteristics of nodular cast iron well cover are also important reasons for his high praise:

1、韧性好。冲击值与中碳钢材详尽,是灰铁材料的10倍以上。

  1. Good toughness。 The impact value of medium carbon steel is more than 10 times that of gray iron。

2、抗腐蚀性强。喷水腐蚀试验,九十天的腐蚀量仅为钢管的1/40,是灰铁管的1/10。使用寿命是灰铁管的2倍,是普通钢管的5倍。

2. Strong corrosion resistance. In the spray corrosion test, the corrosion amount in 90 days is only 1/40 of steel pipe and 1/10 of gray iron pipe. The service life is twice as long as that of gray iron pipe and five times as long as that of ordinary steel pipe.

3、塑性好。延伸率≥7/100,与高碳钢材相近,而灰铁材料延伸率为零。

3. Good plasticity. The elongation (> 7/100) is similar to that of high carbon steel, while the elongation of gray iron is zero.

4、无噪音:由于采用防止噪音的专利构造,井盖过车时无声音,不再扰民。

4。 Noise-free: Because of the patented structure to prevent noise, the cover of the well is silent when passing the car and will not disturb the people any more。
