API 7K High Pressure Vibration Oil Field Kelly Hose Mud Pump Rotary Drilling Hose

Application:

The rotary/drilling/cementing hose is used in drilling, cementing, work over services, borehole operation, and as flexible connection between standpipe and swivel, or between pump and standpipe and for the adjustment of installation variance between the drilling pump line and the riser to connect and isolate vibration. It is suitable for delivering large quantity of water-based or oil-based mud pumped out of rotary drilling equipment at high pressure, with the min. aniline point at 66°C. Moreover, it resists to corrosion of hydrogen sulfide and can deliver water, oil, mud and other high-pressure media in borehole operation in the oil field.
