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!

I型刚性防水套管与II型刚性防水套管差别

Time:2019/4/13 4:20:41

    以下详解下I型与II型刚性防水套管的差异,相关常识我们能够查阅参阅下。I型及II型防水套管,适用于铸铁管,也适用于非金属管,但应依据选用管材的管壁厚度批改有关尺度。

 

    翼环及钢套管加工完成后,在其外壁均刷底漆一遍。I型防水套管仅在墙厚等于或使墙面一边或两头加厚为所需铸铁接轮长度时选用。II型套管尺度表列之资料分量为钢套管(套管长度L值按200mm核算)及翼环之分量。

    钢套管及翼环用A3资料制造,T42焊条焊接。I型及II型套管穿墙处之墙面,如遇非混凝土墙面时应改用混凝土墙面,其浇注混凝土规模,I型套管应比铸铁接轮外径大300mm,II型套管应比翼环直径大200mm,并且需将套管一次浇固于墙内。

    套管内的填料应严密捣实。 II型防水套管出的混凝土墙厚,应不小于200mm,否则应使墙面一边或两头加厚,加厚部分的直径,*小应比翼环直径大200mm.I型加厚部分的直径应比接轮外径大300mm.
