Product Description
Rotary Drilling Hose API 7K Certified High Pressure 35-75 Mpa
Product Overview

Rotary Drilling Hose - Lightweight Anti Static Low Friction Liner High Flow Efficiency

Designed for use in sour gas environments, this rotary drilling hose resists hydrogen sulfide (H₂S), acids, and other corrosive agents encountered in challenging fields. It uses H2S-resistant inner tubes, multi-wire steel reinforcement, and safety-tested couplings to ensure secure and leak-free operation under pressure.

Case Study: In the Middle East, a sour gas drilling site frequently replaced corroded hoses due to H₂S exposure. By adopting H2S-rated rotary hoses with stainless inner linings and API 7K flanged ends, the site extended hose life to over 12 months. Leak incidents dropped by 90%, and the hose upgrade became a regional standard across the operator's fleet.
