Rotary Drilling Hose Product Introduction
The Rotary Drilling Hose is a high pressure hose used in oil and
gas exploration to deliver drilling fluids from the mud pump to the
drill string. Designed for extreme working conditions, it features
a reinforced structure with multiple layers of high-tensile steel
wire and synthetic rubber for excellent flexibility, durability,
and resistance to abrasion. The hose is resistant to oil, heat, and
weather, ensuring long service life in harsh environments. It
complies with API 7K standards and is suitable for both onshore and
offshore drilling operations. With its superior performance and
reliability, the Rotary Drilling Hose enhances efficiency and
safety in drilling applications.
