Cardin type---this kind of tuyere stock is consist of adjustable tube， double gimbal hinged expansion joint，bend pipe，peep hole，blow pipe，upper and lower tightening unit. The characteristics are： the expansion joint contains 2 gimbal hinged bellows and spool pipe， no pressure thrust force；The expansion joint can move to every direction because the inner spherical surface，the stretch-compress gap couldn’t be change which caused by movement. We limit the deflection angle by design to ensure efficient blast and no additional force upon circulating duct，middle sleeve and small sleeve. The process of hot blast blow is safe，effective and low consume. It is application for blast furnace above 600m³.Design Pressure：0.3MPa ～ 0.65MPaHot air pressure ：2012°F～ 2516°F
