Donghong "F" type Cup Tester assemblies are designed to be attached to the drill string and then running into the casing beneath the wellhead to pressure test the blowout preventer stack and the wellhead. When the F type Cup Tester is running into the casing beneath the wellhead, pressure is applied to either a test pump, or by hoisting the "F" type 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. Donghong has the sizes, pressure ratings and connections for every single one of your jobs.

Donghong Cup Tester assemblies come standard with internal flush (IF) connections. Other connections are available at an additional cost.

When ordering please specify:

(1)The casing size & weight

(2)The part number

(3)The OD, ID, and drift diameter. Anytime the "F" type Cup Tester is used; care should be taken to ensure that the drill pipes load capacity is not exceeded. This can be checked by adding the weight of the suspended pipe to the vertical load due to pressure. To find this multiply the cup pressure area (IN.2) by the pressure. The table below shows the total load capacity for each size tester.
