萬州值得信賴的排煙管道廠家

什么是風管，常見風管有哪些類型，風管主要指中央空調系統的通風管道，它常常被忽視，但排煙管道卻是空調系統的重要組成部分。風管是由薄鋼板、鋁板、硬聚氯乙烯板、玻璃鋼以及其它復合材料等制成的，值得信賴的排煙管道用于輸送空氣和空氣混合(he)物的各種管(guan)(guan)(guan)(guan)道(dao)的總稱。1、按照材質(zhi)可(ke)(ke)分(fen)為(wei)(wei)：金屬(shu)(shu)風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、非金屬(shu)(shu)風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)。其(qi)中：（1）金屬(shu)(shu)風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)又(you)可(ke)(ke)分(fen)為(wei)(wei)：鋼(gang)板風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、鋁板風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、不銹鋼(gang)風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)等；（2）非金屬(shu)(shu)風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)可(ke)(ke)以分(fen)為(wei)(wei)：硬聚氯乙烯(xi)風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、有機玻璃風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、無機玻璃風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、玻璃鋼(gang)風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)以及(ji)其(qi)它復合(he)材料風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)等；2、按照風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)外(wai)形可(ke)(ke)分(fen)為(wei)(wei)：圓(yuan)形風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、矩形風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)；3、按照通風(feng)(feng)(feng)(feng)空調系統工作壓力可(ke)(ke)分(fen)為(wei)(wei)：高壓風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、中壓風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、低(di)壓風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)(guan)三個類別，
