1. Purpose: suitable for rotary hose for flexible connection between the top of the drilling riser and the vertically systems, and for the adjustment of installing error between the drilling pump line and the riser for the connection and vibration isolation. It is also suitable for delivering in large quantity at high pressure, water-based or oil-based mud with the min. aniline point at 660Cpumped out of rotary drilling equipment. Moreover, it resists to corrosion of hydrogen sulfide and delivers water, oil, mud and other high-pressure media in borehole operation in oil field.
2. Construction: It made of inner sub or stainless steel armor inner tube, carbon fiber reinforce sub, middle sub, steel wire reinforce sub (Steel cauterization line reinforce sub), and carbon fiber outer sub.
