Rotary Drilling Hose Product Introduction
A Rotary Drilling Hose is an essential component in oilfield
drilling operations, primarily used to transfer drilling mud at
high pressure. Constructed with premium synthetic rubber and
reinforced with multiple steel wire layers, it withstands extreme
pressures and challenging environments. This hose is resistant to
oil, heat, and abrasion, ensuring durability and long-term
performance. It meets API 7K requirements, guaranteeing safety and
reliability for both land and offshore drilling rigs. The Rotary
Drilling Hose is available in various pressure ratings and sizes to
suit different operational needs, providing a stable and efficient
solution for drilling fluid transportation.
