Keyed Thermal Travel Joint (KTTJ)
Vanguard Oil Tools & Services
KTTJ is a Travel Joint, which will be located below the Mechanical-set Liner Hanger and has effective travel of 15 feet.
The Travel Joint is keyed to allow for transmitting torque through the entire assembly, and is fitted with 600 deg F seals. Pressure Rating is 3000 psi. Typical operations include thermal expansion and contraction during production or for injection wells . The Travel Joint can also be run in hole pinned in the closed or open position.
The travel joint can be manufactured in all sizes and lengths for thermal expansion or contraction applications as well as completion or liner space outs.
Once weight is applied from above and the pins shear, the travel joint can be spaced out to accommodate thermal expansion or contraction.
