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!

  如何选择合适的刚性防水套管型号?

  防水套管系列越来越多,随着社会进步,经济的发展,河南伟创从来没停止放弃对防水套管产品的研究改进,生产出各种能发挥不同作用的新型的产品。

  刚性防水套管是钢管外加翼环(钢板做的环形套在钢管上),装于墙内(多为混凝土墙),用于一般管道穿墙,利于墙体的防水。

  刚性防水套管又有A型B型之分,A型适用于钢管,B,C型适用于球墨铸铁钢管及铸铁管。从标准上讲又有02S404 S312等标准图集,在刚性防水套管选型或加工时,应满足管路设计工况及安装的要求,必要时,防水套管的穿墙壁厚、轴向推力等应经结构工程师确认。

  防水套管的安装位置应尽量避开沉降缝、伸缩缝或二个较近距离的构(建)筑物。特殊需要时,需经由结构工程师选用。当穿墙管的材质和外径等超出本图集范围,应注意对刚性防水套管的结构形式、尺寸及缝隙内采用的填料等进行必要的调整和修正。而用于饮用水水池的防水套管,其密封圈、密封膏、防护涂料等应无毒。
