The High Strength Kelly Hose is a critical component in rotary drilling operations, designed to deliver drilling fluids under extreme pressure while maintaining flexibility and durability. Manufactured in accordance with API standards, this hose ensures reliable performance in the most demanding oilfield environments.
1. Primary Purpose and Applications
- The High Strength Kelly Hose serves multiple essential functions in drilling operations:
- Flexible Connection: Provides a flexible link between the top of the drilling riser and the vertically moving swivel (water faucet) in oil drilling and mud circulation systems. This flexibility accommodates the vertical movement of the traveling block during drilling operations.
- Installation Adjustment: Compensates for installation misalignments between the drilling pump line and the riser, while also providing vibration isolation to protect connected equipment from damaging oscillations.
- High-Pressure Fluid Delivery: Designed for the high-volume, high-pressure transfer of water-based or oil-based drilling muds pumped from rotary drilling equipment. The hose is suitable for fluids with a minimum aniline point of 66°C (150°F), ensuring compatibility with various mud formulations.
- Corrosion Resistance: Constructed to resist corrosion from hydrogen sulfide (H2S) and other aggressive elements encountered in sour service environments.
- Multi-Purpose Capability: Suitable for delivering water, oil, mud, and other high-pressure media during borehole operations in oilfields.
2. Product Classification
The High Strength Kelly Hose is available in two primary reinforcement configurations:
- Steel Wire Reinforced Type: Features multiple layers of high-tensile steel wire spiral reinforcement for maximum pressure containment.
- Steel Chain Link Reinforced Type: Utilizes interconnected steel links for enhanced flexibility and resistance to crushing in severe service conditions.
4. Certification and Standards
- API Emblem License Number: 7K-0376
- Applicable Standards: API Spec 7K / SY/T5469
This certification confirms that our manufacturing facility and quality management systems meet the rigorous requirements of the American Petroleum Institute for drilling equipment.
5. Key Performance Features
- High Pressure Rating: Engineered to handle extreme working pressures encountered in deep drilling operations.
- Flexibility: Maintains bend radius capability while under pressure, allowing smooth operation with traveling block movement.
- H2S Resistance: Suitable for sour service environments where hydrogen sulfide is present.
- Temperature Tolerance: Compatible with drilling fluids up to 66°C (150°F) aniline point.
- Abrasion Resistance: Durable construction withstands the abrasive nature of drilling muds and external mechanical wear.
