High-Pressure Underbalanced Drilling Hose - API 7K FSL 1 Certified Flexible Rotary Hose for Oil & Gas Applications
The High-Pressure Underbalanced Drilling Hose (Product No.: UDG-SZ) is an API 7K FSL 1-certified flexible rotary hose designed specifically for underbalanced drilling and well control applications. Built to handle extreme working pressures and dynamic operational loads, it ensures safe, reliable, and efficient fluid transfer between the standpipe and swivel or top drive during rotary drilling operations.
Key Features
- API 7K FSL 1 Certified — Fully compliant with API 7K standards for rotary and mud circulation equipment, ensuring global quality and reliability.
- High Working Pressure & Flexibility — Designed to handle extreme drilling pressures while maintaining smooth flexibility and vibration absorption.
- Multi-Layer Reinforced Construction — High-tensile steel wire spiral reinforcement provides superior burst and fatigue resistance under pulsating pressure conditions.
- Durable Outer Cover — The abrasion, oil, and weather-resistant rubber cover ensures long-term durability in harsh field environments.
- Anti-Kinking & Fatigue Resistance — Engineered structure minimizes stress concentration during repetitive bending and movement.
- Wide Temperature Range — Performs reliably from -40°C to +120°C, suitable for both arctic and tropical drilling sites.
Applications
- Underbalanced Drilling Operations
- Rotary and Top Drive Drilling Systems
- Mud Circulation and Cementing Lines
- Well Control and Managed Pressure Drilling
- Onshore and Offshore Drilling Rigs
Installation & Maintenance Guidelines
- Inspect Before Use: Verify hose integrity and fitting connections before installation.
- Correct Orientation: Ensure the hose is properly aligned to prevent twisting and kinking.
- Use Certified Fittings: Always connect using API-compliant couplings or flanges for safety and performance.
- Regular Pressure Testing: Conduct hydrostatic pressure tests periodically as recommended by the manufacturer.
- Proper Storage: Store in a cool, dry area away from direct sunlight, ozone, or petroleum vapors.
Frequently Asked Questions (FAQ)
The Underbalanced Drilling Hose delivers high-pressure drilling mud or gasified fluids between the pump and drill string during underbalanced drilling operations, allowing precise pressure control.
API 7K FSL 1 ensures the hose meets the American Petroleum Institute’s performance and safety standards for rotary drilling and mud circulation systems, guaranteeing high reliability.
Yes. The hose is specifically designed to manage gasified drilling fluids and air/mist circulation while maintaining consistent internal pressure.
Unlike standard mud hoses, the Underbalanced Drilling Hose is designed for gasified fluid transfer and high-frequency vibration environments, featuring enhanced fatigue resistance and flexible structure.
