1、 薄鋼板矩形風管的剛度不夠,表現形式：風管的大邊上下有不同程度的下沉，兩側面小邊稍向外凸出，有明顯的變形。重慶不銹鋼通風管對產生的原因分析：① 制作風管的鋼板厚度不符合施工及驗收規范的要求；② 咬口的形式選擇不當；③ 沒有按照《施工及驗收規范》要求，對于邊長≥630 mm或保溫風管≥800 mm，其管長在1 200mm以上，均應采取加固措施。2 、薄鋼板矩形風管扭曲、翹角,表現形式：風管表面不平；對角線不相等；相鄰表面互不垂直；兩相對表面不平行及兩管端平面不平行等。不銹鋼通風管產生的原因分析：① 矩形板料下(xia)料后，未對四個(ge)(ge)角進行嚴格的角方測量(liang)；② 風管的大(da)邊(bian)或小邊(bian)的兩個(ge)(ge)相對面的板料長(chang)度和寬(kuan)度不相等；③ 風管的四個(ge)(ge)角處的咬(yao)口寬(kuan)度不相等；④ 手(shou)工咬(yao)口合縫(feng)受力不均。
