Cup Testers

Cup tester assemblies are designed to be attached to the drill string and then low- ered into the casing beneath the wellhead to pressure test the blowout preventer stack and the wellhead. When the cup tester is lowered into the casing beneath the well- head, pressure is applied to either a test pump, or by hoisting the cup after filling the hookup with water. The latter method is fast and accurate. The cup tester assemblies are rated to the API standard mill test pressure for casing sizes up to 10,000 psi. Cup test- er has the sizes, pressure ratings and con- nections for every single one of your jobs. Cup tester assemblies come standard with internal flush (IF) connections. Other con- nections are available at an additional cost.
