Drilling hose is also used to adjust the installation mistake between drilling pipe line and stand pipe to avoid shake. To transmit high pressure oil or water based mud.


Our high-pressure frac hose is a composite hose that can be readily manufactured to multiple lengths, from 2- to 4-in. ID, and pressures up to 15,000 psi to meet your individual requirements. This hose provides improved frac media resistance and enhanced flow rates, which enables you to enhance your frac operation.

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.
