外观检查：白铁皮通风管道制作时，其所用板材、型材以及其他主要成品材料制作要求十分严格。焊缝应作外观检查，不应有气孔、砂眼、夹渣、裂纹等缺陷，焊接后钢板的变形应矫正。

Appearance inspection: When making white iron ventilation ducts, the production requirements for the plates, profiles, and other main finished materials used are very strict. The weld seam should undergo visual inspection, and there should be no defects such as pores, sand holes, slag inclusions, cracks, etc. The deformation of the steel plate after welding should be corrected.

材料制作：白铁皮通风管道加工制作保温层用聚苯乙烯泡沫板制作，泡沫板密度:40㎏/m3，厚度35㎜(表面温度不得低于5℃)，保温层边部接合部位采用梯台或榫槽结构，用树脂粘贴.外表面用铝箔布裹住，用热敏胶带粘贴严密，风道外表面不得有结露现象。

Material fabrication: processing and manufacturing of galvanized iron ventilation duct The insulation layer is made of polystyrene foam board, with density of 40 kg/m3 and thickness of 35 mm (surface temperature shall not be lower than 5 ℃). The junction part of the insulation layer edge adopts ladder or mortise structure, which is pasted with resin. The outer surface is wrapped with aluminum foil cloth, and tightly pasted with thermal sensitive tape. The outer surface of the air duct shall be free of condensation.

整齐平直：白铁皮通风管道加工制作的风道与风口接合用带保温层的软管连接。白铁皮通风管道制作的风道安装应平、直，主风道安装不直度≤1.5㎜/m，不平度≤1㎜/m。白铁皮通风管道制作和配件表面平整、圆弧均匀、纵向接缝应错开，咬口缝应紧密，宽度均匀。

Neat and straight: The air duct produced by processing the white iron sheet ventilation duct is connected to the air outlet using a hose with an insulation layer. The installation of the air duct made of white iron sheet ventilation duct should be flat and straight, with an unevenness of ≤ 1.5 mm/m for the main air duct installation and ≤ 1 mm/m. The production of white iron ventilation pipes and accessories should have a flat surface, uniform arc, staggered longitudinal joints, tight bite seams, and uniform width.

配件偏差:澳门正版内部资料大公开铁皮风管加工制作配件，外径或外边长的允许偏差:小于或等于300㎜为-1㎜;大于300㎜为-2㎜.风道系统内所有直角转弯处均安装消声弯头，消声弯头内设镀锌铁板导流片。白铁皮通风管加工制作的风道采用机械咬口，规整严密，接口内表面打玻璃胶.

Deviation of accessories: Jinan iron sheet air duct processing and manufacturing accessories, allowable deviation of outer diameter or outer edge length: less than or equal to 300mm is -1mm; If it is greater than 300mm, it is -2mm. Silencing elbows are installed at all right angle turns in the air duct system, and galvanized iron plate guide vanes are installed inside the silencing elbows. The air duct made of white iron sheet ventilation pipe adopts mechanical bite, which is neat and tight, and the inner surface of the interface is coated with glass glue
