Thank you for your attention to ZhongYuan water supply equipment [Knowledge News Information] column! The summer solstice is one of the early confirmed solar terms in the 24 solar terms. In the seventh century BC, the ancestors used Tugui to measure the sun's shadow, and determined the summer solstice. Although the summer solstice indicates that the hot summer has arrived, it is not hot yet. The temperature will continue to rise for a period of time after the summer solstice. It will be hot in about twenty or thirty days. After the summer solstice, the ground is strongly heated and the air convection is vigorous, and thunderstorms often form from afternoon to evening. ZhongYuan remind you Construction of chemical and municipal pipelines in power plants industry customer friends: the weather is hot, pay attention to heatstroke prevention!

生产直埋式波纹补偿器有哪些要求?

  1.保温管顶的埋深一般不超过1.2米,但也尽量不要小于0.7米,,保温管可直接埋在各种管道下面。

  2.直埋式波纹补偿器允许不超过1.5倍公称压力的系统水压试验。

  3.直埋式波纹补偿器安装完毕进行系统水压试验前,要将管道两端固定,防止内压推力拉伸补偿器。文章来源:直埋式波纹补偿器。

  4.直埋式波纹补偿器安装不必冷紧,也不必按全线钢管接好后再割下和膨胀节等长管道之后再焊接的方法。使用直埋型膨胀节,不必设导向支架。

  5.保温管埋于地下时,四周需用粒度小于20毫米的砂子填充,然后再覆盖原土,填充砂子的厚度不小于200毫米。

  6.安装时要注意保证导流套筒的方向与流动方向的一致。

  7.直埋式波纹补偿器内介质应进行除游离氧和除氯离子处理,氯离子含量不得超过25PPm。
