(1)按照规范要求，严格控制每种无法兰接头使用范围，如“s”、“c”形插条使用范围是矩形风管长边不大于630mm，立咬口不大于lOOmm。立咬口90度贴角宽度要和立咬口高度相一致，90度应准确，接口合口连接翻边时顺序逐件敲合，pvc通风管道厂家，并背后垫以方铁，使翻边立面平整，90度线平直。

(1) according to the specification requirements， strict control of each kind of flange joint use， such as 's'， 'C' shaped cutting scope of rectangular wind the long side is not greater than 630mm，白铁通风管道， vertical bite is not greater than lOOmm.
