Renown - Model RDS -Cast Iron Wireline or Mechanical Set Cement Retainers
The RDS Cast Iron Wireline and Mechanical Set Cement Retainers are designed for robustness and reliability in high-pressure, high-temperature well environments. These retainers feature a positive, pressure-balanced sleeve valve that can be operated simply by adjusting the tubing. They are engineered to prevent premature setting due to well debris or rough handling, ensuring secure operation. Metal back-up rings within the retainers prevent rubber extrusion under high pressures and temperatures, and as pressure increases, the metal-to-metal contact establishes a more secure seal. An internal ratchet lock ring holds the induced dynamic force during the setting process, maintaining continuous compression of the packing element regardless of pressure differentials. Furthermore, case-hardened, one-piece slips at each end are designed to anchor into the hardest casing, providing additional reliability and performance in demanding well conditions.
The RDS Cast Iron Wireline or Mechanical Set Cement Retainers are rugged, and proven. Both models feature a positive, pressure balanced sleeve valve which is opened or closed simply by lowering and raising the tubing. Positively secured packing element and one piece slips combine to premature setting due to well debris or rough handling and assures protection from the hazards of high speed running in the well. The metal back-up rings prevent extrusion of the rubber at high pressures and temperature. Because of their design, the metal to metal contact developed by these back-up rings is made more secure by pressure increases. An internal ratchet lock ring retains the dynamic force induced in the retainers during the setting operation. This simple mechanism assured continued compression of the packing element regardless of pressure differentials. Case hardened, one piece slips, designed to bite into the hardest casing are locate at each end of the retainer.
