STARSE SPEJ Pup Joint
SPEJ hydraulic expansion pup joint is a new type of hydraulically activated expansion joint, which is used to compensate for the elongation or shortening of the tubing caused by external factors such as temperature and pressure, and absorb the external tensile force or compression force on the pipe column. The expansion joint can be activated by pressure only and is easy to operate. It is suitable for various well types and wells, especially for large displacement wells and horizontal wells.
Features
- Full bore design, matching the inner diameter of the tubing;
- Telescopic length 10 feet;
- The tool can be locked in three states: closed, fully open and half open;
- The shear pressure value can be adjusted by adjusting the number of shear screws;
The piston adopts a skeleton seal configuration, which has strong wear resistance and reliable sealing;
During the lowering process, it can withstand 60t tensile force or downward pressure, which is particularly suitable for wells with complex wellbore trajectories such as large displacement and horizontal wells;
Especially suitable for oil and gas wells with significant pressure effects such as water injection wells;
- Activated by pressure, simple and convenient operation;
- Select high-quality alloy materials to meet the requirements of working conditions.
