Hongruntong Premium Rotary Drilling Hoses
Engineered for rigorous drilling environments, our API 7K-compliant rotary drilling hoses integrate multi-layered steel wire reinforcement and high-abrasion synthetic rubber compounds to withstand dynamic pressure surges (up to 5,000 PSI) and aggressive drilling muds. Optimized for deep-well drilling, horizontal directional drilling (HDD), and subsea exploration, these hoses feature anti-twist helix technology to prevent kinking during high-torque operations.
The chemically resistant inner liner ensures compatibility with oil-based muds, acids, and geothermal brines, while the weather-resistant outer cover resists UV degradation and saltwater corrosion. Compatible with top drives, swivel joints, and mud circulation systems, each hose undergoes hydrostatic testing and impulse cycle validation to meet ISO 14692 and EN 12115 standards.
