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

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)行標準：標準號: GB/T 9900-2008 《橡膠或塑料涂覆織物 通風管》規(guī)定了橡膠或塑料涂覆織物通風管的分類、結(jié)構(gòu)、技術(shù)要求、試驗方法、檢驗規(guī)則、包裝、標志、運輸和貯存等。

Executive standard: Standard No.: GB/T 9900-2008 "rubber or plastics coated fabrics" provisions of the ventilation pipe classification, rubber or plastics coated fabrics of ventilation pipe structure, technical requirements, test method, inspection rules, packaging, marking, storage and transportation etc..

耐風壓性：通風管經(jīng)耐風壓試驗后不得產(chǎn)生通風管脫節(jié)、涂覆布撕裂、接縫開口等現(xiàn)象。通風管直徑膨脹率不得大于3.0%。通風管應根據(jù)巷道及風機風量大小等要求選擇適當規(guī)格，連接時注意氣流方向。

Air pressure resistance: after ventilation pipe has been tested by wind resistance test, no ventilation pipe can be disconnected, coating cloth torn and seam opening. Ventilation pipe diameter expansion rate shall not be greater than 3%. The ventilation pipe shall be selected according to the air flow rate of the tunnel and the fan, and the direction of air flow shall be taken into account when connecting.
