API 7k API 17K Rotary Drilling Hose Drilling Rig Work Process
Rotary Drilling System
Hongruntong Marine Rotary Drilling Hose
Key Benefits at a Glance:
● Built for Extreme Pressure: Can handle working pressures up to 15,000 psi—ideal for
high-pressure rotary drilling and circulation.
● High Flexibility in Tough Environments: Despite its tough construction, the hose remains flexible,
ensuring easy handling and installation in confined spaces.
● Resistant to Harsh Fluids & Chemicals: Specially designed to resist drilling mud, crude oil, solvents,
and other harsh chemicals.
● Durable in All Weather: The EPDM cover withstands UV rays, ozone, and extreme
temperatures, ensuring the hose is tough against weathering and
abrasion.
Design & Composition
The Rotary Drilling Hose is engineered to stand up to the rigorous
demands of the oil and gas industry, where reliability is
paramount. Our advanced multi-layer construction incorporates
high-quality materials to provide exceptional performance:
● Inner Liner:
Material: Oil-resistant synthetic rubber
Purpose: Smooth, efficient flow of drilling fluids, resistant to
corrosion and wear from harsh substances like drilling mud and
crude oil.
● Reinforcement:
Material: High-tensile textile cords and steel wire helix
Purpose: Provides strength to the hose, handling high pressures and
absorbing the mechanical stress generated by rotary drilling and
movement. The helix wire prevents kinking and helps with
flexibility.
● Outer Cover:
Material: EPDM (Ethylene Propylene Diene Monomer)
Purpose: Offers resistance to external wear, including abrasion,
ozone, UV rays, and extreme environmental conditions. The durable
outer cover keeps the hose protected during extended use.
Key Applications
● Drilling Operations: Used to transport drilling fluids, mud, and slurries to and from
the wellbore, maintaining pressure and flow in high-intensity
conditions.
● Offshore Platforms: Designed to withstand the demanding conditions of offshore
drilling, handling both high-pressure fluids and rough weather
conditions.
● Cementing: Ideal for transporting cement slurries during casing jobs,
ensuring the structural integrity of wells by enabling efficient
cementing.
● Mud Circulation Systems: Facilitates the continuous circulation of drilling mud and cools
the drill bit, stabilizing the wellbore and ensuring efficient
cutting removal.
