PME API 7K Hoses Grade D WP 5000 Psi
Our API 7K Grade D rotary drilling hose is specifically engineered to meet the rigorous demands of modern oil and gas drilling.
Designed for high-pressure applications, this hose serves as a critical flexible connection between the standpipe and swivel, or between the mud pumps and standpipe, ensuring efficient and safe fluid transfer on drilling rigs.
With a formidable 5000 PSI working pressure, it delivers exceptional performance and reliability in the toughest operational environments.
Built to comply with the stringent API Spec 7K standards, our Grade D hose provides superior resistance to abrasion, oil, and harsh weather conditions, guaranteeing a long service life and reduced downtime.
It’s the ideal solution for high-pressure mud hose applications and essential for any drilling operation requiring robust and dependable fluid conveyance.
Key Feature
- API 7K Certified: Manufactured and rigorously tested to meet or exceed API Specification 7K, guaranteeing compliance with industry safety and performance benchmarks for rotary drilling hose.
- Exceptional Pressure Rating: Engineered for 5000 PSI working pressure and 7500 PSI test pressure, offering a 2.5:1 safety factor for maximum operational security.
- Robust Internal Construction: Features a premium, oil-resistant inner tube (typically Nitrile or HNBR) capable of handling various drilling fluids, including water-based and oil-based muds.
- High-Tensile Reinforcement: Reinforced with multiple layers of high-strength spiral steel wire or cable, providing unparalleled strength, flexibility, and resistance to kinking and collapse.
