Mud Hose UV Resistant Pressure Rated Steel Wire Reinforced Core
Abrasion Resistant Outer Cover
Rotary Drilling Hose Product Introduction
Engineered for mobility and quick deployment, this ultra-flexible rotary drilling hose combines reduced bending radius with high-pressure endurance. It allows easy rig-up and rig-down on mobile drilling units and directional drilling setups, improving handling in compact workspaces.
The anti-abrasion cover and strong tensile layers allow frequent repositioning without degradation.
( Case: A portable rig in Canada working across frozen terrain faced delays due to rigid hoses cracking during cold repositioning. Switching to low-temperature rotary hoses with improved bend radius eliminated breakages. Downtime dropped by 30%, and daily repositioning was completed 45 minutes faster on average. )
