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!

  防水套管的封堵技术有哪些?

  1、确定标高和安装中线:校核套管中线和标高,确定穿墙管安装标高或中线位置,在穿墙管上定位、画线,调整和固定管道的支吊架及坡度。

  2、封堵前应进行:在管道进入套管之前,应先清除套管及管道内的杂物和铁锈,使其表面无锈蚀,漆皮,污物,且干净,干燥;并在管壁刷防锈漆,防锈漆干透之后才将管道穿过套管。

  3、穿墙管焊接或点焊螺纹钢:根据核定安装间隙,在穿墙管与套管*线确定焊接钢筋或圆钢的大小和位置,在穿墙管外壁焊接或点焊25mm螺纹钢(螺纹钢尺寸可调整)一圈。

  4、套管底部焊垫块:垫块用于支撑和固定穿墙管,在套管底部(套管外缘靠近穿管处10mm内)焊垫块一~三块(垫块尺寸50*50mm,厚度根据间隙大小确定),用以支撑或固定穿墙管。

  5、补涂防锈防腐涂料:焊接完成后根据原钢管防腐防锈方法补涂防腐防锈涂料。

  6、管道穿墙定位:确定和核准安装位置后,采用吊机将管道调运至安装位置,根据管道设计坡度和走向与管道支座或其它管道附件进行初步固定。

  7、固定穿墙管:穿管前在套管底部或靠近底部20Cm范围内点焊或焊接1-3个钢板垫块,厚度大于等于25螺纹钢,调整穿墙管与套管相对位置,尽量使套管与穿管*位置一致,便于填塞封堵填料。
