1、风管安装的位置、标高、走向,应符合设计要求.现场风管接口的配置,不得缩小其有效截面;2、风管接口的连接应严密、牢固.风管法兰的垫片材质应符合系统功能的要求,厚度不应小于3mm.垫片不应凸入管内,亦不宜突出法兰外;3、可伸缩性金属或非金属软风管的长度不宜超过2m,并不应有*弯或塌凹;4、不锈钢板、铝板风管与碳素钢支架的接触处,应有隔绝或防腐绝缘措施;5、风管与砖、混凝土风道的连接接口,应顺着气流方向插入,并应采取密封措施.风管穿出屋面处应设有防雨装置;6、风管安装前,应清除内、外杂物,并做好清洁和保护工作;7、连接法兰的螺栓应均匀拧紧,其螺母宜在同一侧;8、柔性短管的安装,应松紧适度,无明显扭曲.在前期安装山东通风管道时,我们应注意并达到其安装要求,以使山东通风管道在后期使用时,能够有效地避免由于安装不合格而对通风管道系统造成的伤害!望采纳。

风管安装　　（1）一般规定　　　①风管和空气处理室内，敷设电线、电缆以及输送有毒、易燃、易爆气体或液体的管道。 ②风管与配件可拆卸的接口及调节机构（风阀及自控装置）不得装设在墙或楼板内，以免影响*作和维修　　 ③风管及部件安装前，应清除其内外杂物及污物，并保持清洁。（2）风管安装的技术规定 ①现场风管接口的配置，不得缩小其有效截面。这里是指风管与配件，部件及设备相接部位的连接管。 ②支、吊架不得设置在风口、风阀、检查门及自控机构处，吊杆不宜直接固定在法兰上，以免风管变形与影响维修。 ③支、吊架的间距，如设计无要求，应符合下列规定
