通風(fēng)管按涂覆布材料分為橡膠涂覆布正壓通風(fēng)管、塑料涂覆布正壓通風(fēng)管和橡塑涂覆布正壓通風(fēng)管；又可按形狀結(jié)構(gòu)分為螺旋通風(fēng)管，伸縮通風(fēng)管。

The ventilation pipe is divided into rubber coating cloth, positive pressure ventilation pipe, plastic coating cloth, positive pressure ventilation pipe and rubber plastic coating positive pressure ventilation pipe according to the coating cloth material, and can be divided into spiral ventilation pipe and telescopic ventilation pipe according to the shape structure.

生產(chǎn)執(zhí)行標(biāo)準(zhǔn)：標(biāo)準(zhǔn)號: GB/T 9900-2008 《橡膠或塑料涂覆織物 通風(fēng)管》規(guī)定了橡膠或塑料涂覆織物通風(fēng)管的分類、結(jié)構(gòu)、技術(shù)要求、試驗(yàn)方法、檢驗(yàn)規(guī)則、包裝、標(biāo)志、運(yùn)輸和貯存等。
