Rotary Drilling Hose Lightweight Anti Static Low Friction Liner High Flow Efficiency
Rotary Drilling Hose Product Introduction
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: 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. )
