RSSD NON-ELASTOMERIC SLIDING SLEEVES

The Models RSSD Non-Elastomeric Circulating Sliding Sleeve, is a high performance, equalizing sliding sleeve, which allows communication between the tubing and annulus for circulation or selective-zone production. The external circulating sliding sleeve allows hydraulic setting of packers and verifies the seal integrity between the packer and the tubing.

Features

• A specially designed diffuser ring made of high strength thermoplastic is critically spaced between the flow ports and the upper packing unit. This prevents damage to the upper packing unit during shifting by controlling the rush of fluid or gas, and lessens the likelihood of tool string damage by providing for slow equalization of high differentials

• Mill slots replace drill holes as flow ports on both the housing and the insert to allow more flow area, reduce erosion and allow higher torque and tensile strength through the sleeve

• Locating the threaded connection inside the primary seal stack eliminates the need for O-ring thread seals and reduces the number of potential leak paths

• A locking, angled torque shoulder replaces traditional square shoulder to allow higher torques and reduce thread back off

• Modular design permits conversion from a Model RSSD or vice versa by only changing the upper and lower subs

• Proprietary non-elastomeric and elastomeric compounds enhance a sealing system designed for diverse environments
