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)!

刚性套管与柔性套管区别在哪

Time:2019/3/25 14:37:31

    柔性防水套管一般适用于管道穿过墙面之处受有振荡或有紧密防水要求的构筑物,刚性防水套管一般适用于管道穿过墙面之处要求一般防水的构筑物;柔性及刚性防水套管穿墙处之墙面,如遇非混凝土时应改用混凝土墙面,并且需将套管一次凝固于墙内;防水套管于修建、化工、钢铁、自来水、污水处理等单位。

 

    刚性防水套管是钢管外加翼环,装于墙内,用于一般管道穿墙,利于墙体的防水;柔性防水套管除了外部翼环,内部还有档圈之类的,法兰内丝,有成套卖的,也可自己加工,用于有减震需求的管,如和水泵衔接的管道穿墙时。

    也就是说,假如考虑墙体两面的防水功能,就要选用柔性防水套管;假如仅仅是考虑管道的穿墙,而不考虑穿墙后,墙体两面的防水功能以及管道的位移变形,就可以选用刚性防水套管。

    钢性防水套管适用于管道穿墙处不接受管道振荡和弹性变形的构筑物,适用于管道穿墙处空间有限或管道装置先于构筑物或管道的更新。关于有地震设防要求的区域,如选用钢性防水套管,应在进入池壁或修建物外墙的管道上就近设置柔性衔接。A型适用于钢管,B,C型适用于球墨铸铁钢管及铸铁管。
