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)!

球形补偿器怎样做好防腐蚀

    防腐蚀补偿器又称直埋式波纹管膨胀节,直埋式波纹补偿接头。该产品是选用耐蚀金属作维护层金属波纹管的*元件,和管道的运用温度选用聚四氟乙烯等有机资料,密封波纹管补偿器与端管10,导向组件9由夹子6、8夹紧密封,使腐蚀介质与波纹管外外表阻隔,然后维护波纹管不被腐蚀。

 

    为了确保密封效果,端管10,导向组件与密封波纹管补偿器的合作面应进行机械加工,为了确保直埋式波纹补偿器的补偿量,密封波纹补偿器的补偿才干应略大于直埋波纹补偿器的补偿量,能够选取直埋波纹补偿器的补偿量的112倍。当运用温度在150e以下时,可选用乙丙橡胶。假如介质为高温蒸汽,则有必要选用氟塑料、硅橡胶等。

    密封环结构在球形补偿器的导向组件与端管之间加上两个密封环,密封环之间的空隙使水分被阻隔。选用耐蚀金属作维护层金属波纹管是波纹管补偿器的*元件,金属波纹管是一个薄壁件,波纹管补偿器的防腐主要是波纹管的防腐。

    咱们选用的波纹管是多层结构的,在多层波纹管的*外一层选用特别资料,因为*外层资料对土壤中的腐蚀介质有较强的耐腐蚀性,整个补偿器也就具有较强的耐腐蚀性,在规划中应留意以下几点:波纹管的*外层与其他各层一起成型,因而要求该层金属资料与其他各层金属资料具有附近的延伸率。

    波纹管与接收或法兰的焊材应按*外层资料的成份挑选,这样才干确保焊缝的耐腐蚀性。其它与腐蚀介质触摸的零件应根据腐蚀介质的状况来挑选资料或添加必要的腐蚀裕量。这种结构也能够用于管道内介质为腐蚀介质的场合,这时将多层波纹管*内层更换为特别资料。
