，在相同管徑與水力坡降條件下，雙壁波紋管與水泥管的輸水量相差30%以上。 </p> <p> 4、運輸安裝與施工比較：雙壁波紋管重量輕，運輸和搬運方便，施工速度快，安裝費用低，云南UPVC雙壁波紋管直銷價格，根據測算：如DN500mm管材用3-4人既可安裝，時間只需5-6min，正常情況下，從開挖(用機械開挖)――平基――裝管――回填，8小時可裝管40m，云南UPVC雙壁波紋管直銷價格，比同口徑的水泥管安裝時間節(jié)省50%以上。而水泥管需機械吊裝，所以在安裝費中還要扣除機械臺班費。波紋管、HDPE雙壁波紋管、昆明PE雙壁波紋管，昆明元森商貿。云南UPVC雙壁波紋管直銷價格</p><div

波紋管是指用可折疊皺紋片沿折疊伸縮方向連接成的管狀彈性敏感元件。波紋管在儀器儀表中應用***，主要用途是作為壓力測量儀表的測量元件，將壓力轉換成位移或力。波紋管管壁較薄，靈敏度較高，測量范圍為數十帕至數十兆帕。它的開口端固定，密封端處于自由狀態(tài)，并利用輔助的螺旋彈簧或簧片增加彈性。工作時在內部壓力的作用下沿管子長度方向伸長，使活動端產生與壓力成一定關系的位移?；顒佣藥又羔樇纯芍苯又甘緣毫Φ拇笮?。波紋管常常與位移傳感器組合起來構成輸出為電量的壓力傳感器，有時也用作隔離元件。由于波紋管的伸展要求較大的容積變化，因此它的響應速度低于波登管。波紋管適于測量低壓。
