外觀檢查：白鐵皮通風(fēng)管道制作時，其所用板材、型材以及其他主要成品材料制作要求十分嚴(yán)格。焊縫應(yīng)作外觀檢查，不應(yīng)有氣孔、砂眼、夾渣、裂紋等缺陷，焊接后鋼板的變形應(yīng)矯正。

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：白鐵皮通風(fēng)管道加工制作保溫層用聚苯乙烯泡沫板制作，泡沫板密度:40㎏/m3，厚度35㎜(表面溫度不得低于5℃)，保溫層邊部接合部位采用梯臺或榫槽結(jié)構(gòu)，用樹脂粘貼.外表面用鋁箔布裹住，用熱敏膠帶粘貼嚴(yán)密，風(fēng)道外表面不得有結(jié)露現(xiàn)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.

整齊平直：白鐵皮通風(fēng)管道加工制作的風(fēng)道與風(fēng)口接合用帶保溫層的軟管連接。白鐵皮通風(fēng)管道制作的風(fēng)道安裝應(yīng)平、直，主風(fēng)道安裝不直度≤1.5㎜/m，不平度≤1㎜/m。白鐵皮通風(fēng)管道制作和配件表面平整、圓弧均勻、縱向接縫應(yīng)錯開，咬口縫應(yīng)緊密，寬度均勻。

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:濟(jì)南鐵皮風(fēng)管加工制作配件，外徑或外邊長的允許偏差:小于或等于300㎜為-1㎜;大于300㎜為-2㎜.風(fēng)道系統(tǒng)內(nèi)所有直角轉(zhuǎn)彎處均安裝消聲彎頭，消聲彎頭內(nèi)設(shè)鍍鋅鐵板導(dǎo)流片。白鐵皮通風(fēng)管加工制作的風(fēng)道采用機(jī)械咬口，規(guī)整嚴(yán)密，接口內(nèi)表面打玻璃膠.

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
