The flanges manufactured by Qishine are forged flanges. The flanges in the pipeline system are used to connect the pipeline. According to the standard of the petrochemical industry, flanges can be classified into butt welded neck flanges (WN), socket welded flanges (SW), threaded flanges (TH), loose flanges, Lap joint flanges (LJ), slip-on flanges (SO), blind flanges (BL), orifice flanges, spectacle blind flanges, etc.
