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)!

人防套管穿墙套管的区别

Time:2019/4/5 10:44:26

    人防套管,人防密闭套管是同一种套管。穿墙套管为装置套管。差异如下:分类不同:装置工程套管主要有一般穿墙套管、刚性防水套管、柔性防水套管。人防套管和人防防密闭套管多为密肋套管,依据详细情况分辩判别。

 

    装置办法不同:人防内套管装置:当人防密闭外墙施工时,凡穿墙的测压管、取样管与压缩空气管均按下图直接浇入密闭墙内。不得预留孔洞后装置。管道的密闭盘要按规范要求厚度选材,密闭盘焊接应紧密,不得有任何空地和针眼现象,结合密闭,避免渗漏。

    压缩空气管与测压管施工时,两端螺丝需用管箍维护,以确保螺丝扣无缺。管道在打入墙里之前表里要整理,除锈管内并需刷环氧改性漆。穿墙套管装置:套管在装置前应在套管外壁刷底漆一道,套管内应刷防锈漆两道,套管装置前,还应先将套管内用锯末、旧棉絮等进行填充,用胶带将套管两端进行透彻关闭。

    避免其他杂物或混凝土等进入套管。向左转向右转规范不同:在制造人防密闭套管时,翼环和套管的厚度应契合国家规范规范要求,套管翼环两头应该双面满焊,且焊缝丰满、平坦、润滑、无夹渣、无气孔、气泡、无裂纹等不合格现象。

    装置防水套管,柔性防水套管的密封管件时法兰,及阀门密封面及密封垫的光洁度要契合要求,不得有影响密封功能的划痕、斑驳等缺点,并涂沫白凡士林。定额选用一般依据选用套管的图集作法按刚性、柔性、一般穿墙套管考虑。详细定额套用依据当地的定额规则选取。
