Flexible Choke and Kill hoseApplication:
As connection part when drill platform, semi-submersible drilling vessel or drilling vessel moves relatively and for adjustment of the installation variance of the drilling rig. It transfers oil, gas, mud and other high pressure media. It mainly used for connection of inner and outer high pressure choke and kill hose and flexible connection between mud & gas separator and choke manifold.
Standard: API Spec 16C & SY/T5323-2004.
Features: high pressure resistance, thermal insulation, flame-retardant, fire resistance, oil resistance, high abrasion resistance inner wall and long operating life.
Fittings: Swaged fitting, International integral vulcanized, integral flange and union.
