Quick Test Sub (QTS)

DeepWiki – The well service authority

A Quick Test Sub (QTS) is used when pressure testing the pressure control equipment (PCE). The PCE is pressure tested and then broke at the QTS. The PCE is then reconnected at the QTS. The QTS has two O-rings where it was disconnected that can be tested with hydraulic pressure to confirm the PCE can still hold the pressure it was tested to.
