Integral Joint Tubing (IJ)
Description
Integral joint tubing has an external thread at on end and an internal thread at the other end.
This oil pipe can be connected without the use of couplings.
Cylindrical surface, conical surface, spherical surface, and reverse circular cone step surface are arranged successively on the outer end of the external thread and inner end of the internal thread parts.
These metal surfaces form a sealing structure and the first step. On the other side of the external and the internal joints, there is a second step which forms the major anti-torque step.
The second step and the first step form a double-step structure.
Advantages
1. Integral joint tubing is very practical. With the integral joint structure, the oil pipe connecting procedure is saved.
2. Metal sealing, double anti-torque steps, and high-efficiency connecting threads are effectively combined together.
This method has obviously improved the connection strength, sealing effect, and the anti-torque capability.
3. The integral joint tubing can meet the requirements of both normal oil and gas extraction and special working condition of high torsional well repair acid fracturing operation.
This oil pipe can replace a small drill rod and lower the cost of oil field operation.
