Our casing cup tester is designed to be attached to the drill string and then lowered into the casing beneath the wellhead to pressure test the blowout preventer stack and wellhead. When the cup tester is lowered into the casing beneath the wellhead, pressure is applied to either a test pump or by hoisting the type cup after filling the hook-up with water. The latter method is fast and accurate. 

Astarn’s cup tester assemblies are rated to the API standard test pressure for casing sizes up to 10,000 psi. Special reinforcing can be offered on all cup sizes and casing weight ranges to hold up to 15,000 psi. Heavy Duty Packer cup is the least flexible but can also withstand higher pressure.
