Cup Tester

Cup Tester

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 the wellhead.  When the cup tester is lowered into the casing beneath the wellhead, pressure is applied to either a test pump, or by hoisting 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. Special reinforcing can be offered on all cup sizes and casing weight ranges to hold up to 15,000 psi.

When ordering please specify:

  1. ●  Casing size & weight;
  2. ●  Connection.
