High Pressure Rotary Drilling Hose

The High Pressure Rotary Drilling Hose is suitable for flexible connection between the top of the drilling riser and the vertical systems, and for the adjustment of installing variance between the drilling pump line and the riser. It is for connection and vibration isolation. It is also suitable for delivering in large quantity water-based or oil-based mud pumped out of rotary drilling equipment at high pressure, with the min. aniline point at 66A 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.

Composition: It is made of inner rubber layer or stainless steel armored inner tube, carbon fiber reinforcement layer, middle layer, single steel wire reinforcement layer/multi steel wire reinforcement layer, and carbon fiber outer layer.

Classification: single steel wire reinforcement type and multi steel wire reinforcement type. Single steel wire reinforcement hoses are suitable for well site ground usage. Multi steel wire reinforcement hoses are suitable for long-term high altitude hanging.
