严禁使用电焊、气焊割管。
Strictly prohibited in using gas and electric welding cutting conduit.
严禁将脚手架作为电缆管使用。
Strictly prohibited in using the folder as electrical conduit.
锈蚀严重的钢管不得使用；钢管弯制或安装前应将管口及管内杂物清扫干 净，并除去毛刺。
Exist serious corrosi on con duit is not allowed used; the mouse of the con duit as the inner part the debris must be removed before bending or in stallati on
电缆管切割采用手工锯或切割机进行切割，并保证切割面平整且不倾斜；切 割后必须立即将管口毛刺打磨干净，并打磨管口成喇叭型。
Cutting for the conduit adopting in manual saw or machine, and ensure the cutting surface smooth and not tilt; burring after cutting must be immediately, and polished type no zzle into horn.
