Description

QT-1000 was developed in response to an increasing need for a long-reach, high-pressure coiled tubing. QT-1000 also exhibits a higher fatigue cycle life at higher pressures than all lower-strength-rated coiled tubing.

For the appropriate sizes, QT-1000 can be routinely ordered as a True-Taper™ or True-Taper XR string; straight-wall, straight-wall flash-free string; or as a string with an electric wireline or capillary tube installed.
