API 7K Rotary Drilling Hose 2 Inch 40 FT (2000 PSI & 3000 PSI Working Pressure)
In high-pressure mud circulation systems, standpipe-to-swivel and top drive flex lines must endure severe mechanical vibration, high mud velocity, and aggressive chemical exposure. Shanghai PME Industrial manufactures heavy-duty API 7K Rotary Drilling Hoses in 2-inch Inner Diameter (ID) and 40-foot length, specifically designed for high-pressure drilling fluid transport. Certified under API Spec 7K standards, these flexible Kelly and vibrator hoses deliver uninterrupted mud delivery across onshore and offshore rig installations.
Engineered with oil-resistant synthetic rubber inner tubes, multi-layer high-tensile wire braid reinforcement, and extra weather and oil-resistant protective covers, our 2 inch 40 FT rotary hoses are available in 2000 PSI working pressure and 3000 PSI working pressure with Pin x Pin LP (Line Pipe) male connections, serving major oilfield drilling contractors and purchasing engineers across Indonesia.
2 inch ID, 40 FT length, and 2000 PSI working pressure rating along the outer cover.
2 inch ID, 40 FT length, and 3000 PSI working pressure rating along the outer cover.
Coiled 40 FT rotary hoses pre-inspected, stacked, and crated for ocean freight shipment to Indonesian discharge ports.

Application Analysis: API 7K Rotary Hoses for Indonesia Drilling Rigs
In active Indonesian drilling fields across East Kalimantan, Sumatra, and the Java Sea, high humidity, salt fog, and continuous drilling fluid pulsation impose severe demands on mud circulating hoses. Deploying PME API 7K 2" 40 FT rotary hoses addresses primary rig fluid conveyance challenges:
1. Flexible Standpipe to Swivel Connection
Serves as a flexible high-pressure mud transfer conduit between the top of the standpipe and the travelling swivel or top drive, absorbing vertical travel motion and mechanical vibration during drilling operations.
2. Synthetic Rubber Resistance to Oil-Based Mud (OBM)
Formulated with oil-resistant synthetic inner tubes, these hoses prevent interior blistering, swelling, or structural erosion when handling aggressive oil-based muds, diesel-base fluids, and heavy drilling chemicals.
3. Tropical Marine Corrosion Protection
The wire braid reinforcement is protected by an extra oil-resistant outer cover that shields against mechanical scuffing, severe tropical UV exposure, and salt spray corrosion typical of Indonesian offshore and swamp rig locations.
