Stab Sleeve

The Stab Sleeve by Daspit Manufacturing Company is used in low pressure repairs. Several design features make the Stab Sleeve an important asset in riser repairs:

• A wide ring, machined to fit closely to the pipe makes it less likely that the ring will be jammed when being tightened by divers.
• Clamping bolts are purposely staggered so they will not cause pipe denting and slippage at lower tensile loads.
• A wide gasket provides a greater sealing area which is more dependable in corroded riser repairs.
• The Stab Sleeve gasket is composed of quality (BUNA N) nitrile rubber, an industry standard. Other elastomeric compounds can be ordered.
• An 'O' ring is provided to prevent sea water and oxygen intrusion to prevent serious corrosion problems within the tool.
• Grease fittings are part of the design. The grease displaces the sea water within the sleeve, further reducing the possibility of corrosion.
• Each sleeve has a heavy wall, therefore it will last longer in a marine environment above or below the surface of the water.
