Rotary Drilling And Cement Hoses Vibrator Hoses And Mud Delivery
Hoses
For over three decades, Hongruntong Marine has been a leading name
in the manufacturing of rotary drilling hoses, combining
innovation, craftsmanship, and advanced technology to create
products that meet the rigorous demands of the oil and gas
industry.
Our rotary drilling hoses are essential components for oilfield
operations, designed to deliver drilling fluids, including mud,
cement, and other media, with maximum efficiency and reliability.
Built to endure the harshest conditions, these hoses excel in
high-pressure, high-temperature environments while maintaining
superior flexibility and strength.

Crafted for Tough Challenges
The secret behind our product’s performance lies in the materials
and engineering:
The inner tube, made from specially formulated synthetic rubber,
offers excellent resistance to drilling fluids and hydrocarbons.
Multiple layers of high-tensile steel wire reinforcements provide
unmatched strength, enabling the hose to handle extreme pressures.
The durable outer cover, engineered to withstand abrasion,
sunlight, and weathering, ensures the hose retains its performance
in rugged environments.

requirements, including varying lengths, pressure ratings, and end
fittings.
Commitment to Quality and Safety
We prioritize safety and reliability, conducting comprehensive
tests at every stage of production:
Pressure and Burst Testing ensures the hose can perform well beyond
its operational limits.
Temperature Resistance Testing validates functionality in extreme
hot and cold environments.
Inspection of Fittings guarantees leak-free performance and
