API Spec 7K Drilling hose 
APPLICATION:
Suitable for oil drilling, the drilling mud in the delivery system between the top of the riser with the vertical movement of the faucet may be connected to a flexible hose, and applied to the line between the pump and the drilling riser for adjusting misalignment, to facilitate connection and vibration isolation. Also applies to a large number of transport under high pressure from the pump rotary drilling equipment and a minimum aniline point of water-based or oil-based muds 66 ºC, and can anti-corrosive hydrogen sulfide, oilfield downhole operation conveying water, oil, mud high media.
