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)!

选用金属膨胀节时要参照的标准有哪些?

Time:2019/2/27 9:33:29

金属补偿器为补偿因温度差与机械振动引起的附加应力,而设置在容器壳体或管道上的种挠性结构。它作为一种能自由伸缩的弹性补偿元件,具有工作可靠、性能良好、结构紧凑等优点。

在选用金属膨胀节时要参照以下标准:

1、状态 -- 按软管使用时的状态,参照金属软管的正确使用与安装方法与软管在沉降补偿时的较佳长度.软管各种运动状态的长度计算及软管的较小弯曲次数和较小弯曲半径等因素,参数正确选取软管长度,并正确安装。

2、尺寸 -- 软管公称通径,选用接头型式金属膨胀节(主要有法兰联接、螺纹连接、快速接头连接)及尺寸,软管长度。

3、压力 -- 根据金属膨胀节实际工作压力,再查询波纹的公称通径与压力表,决定是否使用不锈钢网套类型的

4、介质 -- 软管中所输送的介质的化学属性,按软管材质耐腐蚀性能参数表,决定软管各零件的材质。

5、温度 --金属膨胀节内介质的工作温度及范围;软管工作时的环境温度。高温时,须按金属膨胀节高温下的工作压力温度修正系数,确定温度修正后的压力,以确定选用正确的压力等级 。
