Purpose:suitable for rotary hose for flexible connection between the top of the drilling riser and the vertically movable water faucet in the oil drilling and mud delivery systems,and for the adjustment of installing error between the drilling pump line and the riser for the connection and vibration isolation.
Scope of application: The hose for well control-GNG high-pressure, fire-resistant and heat-insulation hose assembly is mainly used for the hydraulic control of the BOP for drilling and for hydraulic transmission at high-temperature and flammable places in the metallurgic industry.
Applicable to connection at locations when drill platform, semi-submersible drilling vessel or drilling vessel moves relatively and the installation dimensions of the drill rig subsequently change,and to delivery of oil,gas.mud and other high pressure media (including mainly relief line,blowout control line and choke kill line).
