Coiled Tubing In-Situ Pressure Test Sub
Takes the place of the bottom connection, effectively becoming the tool change joint that has to be broken
Product summary
The Hunting In-Situ Pressure Test Sub was originally designed to reduce time spent pressure testing the broken lubricator connection after tool changes.
The Coiled Tubing In-Situ Pressure Test Sub takes the place of the bottom connection, effectively becoming the tool change joint that has to be broken. As a result of its unique design, it can be tested in isolation to the rest of the rig-up, by the simple use of a small hand pump.
The mid-joint of a Coiled Tubing In-Situ Pressure Test Sub is like any other quick union, except that it has two O-ring seals with a pressure test port between them. This feature is responsible for easy testing of joint integrity.
As noted, this saves pressure testing the whole rig-up, however there is another added advantage in that it allows for the riser system to be pressure tested whilst pressure sensitive equipment (such as perforating guns) are in the riser.
Features
Two O'ring seals to pressure test against via a port
Multi range of flange connections and pressure ratings
Internal bore size range from 3.00" 9.00"

Benefits
Reduces the time spent pressure testing the rig up prior to exposing it to live well pressure
The rig up can be tested whilst pressure sensitive equipment, such as perforating guns are in the riser
Coil Tubing In-Situ Test Sub integral to the CT BOP will save rig up heights
