Kelly Hose

Kelly hose works as the flexible connection between the standpipe and rotary vibrator to deliver mud at a high pressure. It is the necessary part in the oil exploiation and well drilling.

Kelly Hose

Tube: 3/16” thick and black modified nitrile. Specially designed for handling abrasive, corrosive and oil drilling mud

Reinforcement: Multiple layers of textile fabric and steel cable, with one layer middle rubber placed among cable layers

Cover: Black modified nitrile resistant to abrasion, corrosion, cutting, gouging, oil and weather

Temperature: -20℃ to +82℃ ( -4℉ to +180℉ )

Application: Flexible connection between standpipe and swivel (Rotary Drilling) or between pump and standpipe (Rotary Vibrator) for pumping mud at extra high pressure in oil drilling and exploration work.

Kelly Hose meets the high demands of directional drilling and down linking with negative pressure pulses and elevated temperatures. This hose can also be used as a Motion Compensator hose for stabilization of rotary drilling and pumping equipment against vertical wave action on offshore drill platforms. The motion compensator hose is not recommended for phosphate ester fluids.
