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! Thank you for your attention to the Gongyi Zhongyuan Innovation Pipeline Equipment Co., Ltd website (http://ceshi5.66554433.cn)!

使用套筒补偿器要注意防腐蚀

  套筒补偿器的防腐蚀是在各种环境条件下材料的破坏和劣化。金属腐蚀主要是由化学腐蚀和电化学腐蚀引起的。套筒补偿器的腐蚀通常是由直接的化学和物理损坏引起的。腐蚀是导致套筒补偿器损坏的重要因素之一。因此,在使用套筒补偿器时,首先要考虑的是防腐蚀。

  电化学腐蚀以各种形式腐蚀金属。它不仅在两种金属之间起作用,而且由于溶液的溶解性差,氧的溶解性差以及金属内部结构的微小差异。有些金属不耐腐蚀,但它们可以产生非常好的保护膜,即钝化膜,可以防止介质的腐蚀。可以看出,为达到套筒补偿器防腐的目的,一是消除电化学腐蚀;另一种是消除电化学腐蚀;在金属表面上制作钝化膜;非金属材料取代金属材料。

  套筒补偿器的内套管与管道连接,采用高性能自压式动密封的原理和结构,它可以随着管道的伸缩在外壳内进行自动滑动,能适应任何管道的密封要求。外壳与内套筒之间采用新型合成材料密封,能耐高温、防腐蚀、抗老化,适用温度-40℃至150℃,特殊情况下可达350℃。

  套筒补偿器可以保障管道的*运行,具有补偿吸收管道的轴向、横向以及角向的热变形;补偿器可以吸收设备振动,以减少设备的振动对管道产生的影响。
