rotary drilling hose

Certification/Standards: 

API Spec 7K-ISO 14693-NACE MR0175

Recommended For: 

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. 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.
