DSTI's Offshore Oil & Gas Fluid Swivel Joints & Rotary Joints for High Pressure Flexible Moon Pool Drape Hoses

DSTI's field-proven, high pressure inline (HPI) moon pool drape hose fluid swivels are utilized worldwide to extend the life of rig hoses by reducing torsional loads and stress.

Trusted by leading oil and gas equipment manufacturers and operators, DSTI's HPI moon pool hose fluid swivels are utilized in topside and subsea applications where flexible hoses (jumpers) are susceptible to stress and torsion from equipment installation, production, ocean currents and other environment conditions.

Unlike many competitors, DSTI's swivels allow drape hoses and other flexible hoses to rotate at low-torque, even at full operating pressures - extending hose service life, therefore saving time and money from unplanned repair and downtime.

DSTI's swivels are engineered based on project application requirements and qualified to API 6A, 16C, and 17D. The compact design offers reduced weight with heavy-duty internal bearings to support hose loads and are operational for sour service in accordance with NACE MR1075.
