Fluid Sealing Solutions
Fluid Sealing Solutions Moon Pool Drape Hoses
DSTI's high pressure inline (HPI) swivels are utilized on offshore moon pools, managed pressure drilling systems and direct acting tensioner systems where drape hoses are susceptible to added stress and torsion from vessel movement caused by dynamic positioning systems and ocean currents. HPI swivels can rotate in either direction and feature a unique internal design for low-torque rotation at full working pressure.
