Reduce rod pumping cost

TR swivel sucker rod couplings(also know as sucker rod swivel) can significantly reduce the sucker rod pumping cost, power cost and increase your production rate. It can greatly prevent the sucker rod pumping failures in your artificial lift operations.


Main Functions: 
TR swivel sucker rod coupling can greatly reduce the sucker rod pumping cost and mechanical failures like bent rod failures, thread failure, connection failure and sucker rod sticking etc. It can prolong the Maintenance-free operating period for oil wells. It can significantly reduce the friction and load of rod pumps and save power cost and pumping cost. Our swivel coupling can establish articulated juncture between sucker rods, which can provide pump-plunger overtravel and increase your production rate.

Theory of Operation- Hinge Joint (Bone Joint)
TR  swivel sucker rod couplings can establish hinge joints between sucker rods.  TR swivel coupling has
 ability to rotate a full 360° around its own centerline. It can provide around 1” off-center deflection, as picture.  It can automatically adjust the diviation/direction, prevent thread off, over torque and avoid eccentric wear. It is one kind of idea downhole tools to reduce sucker rod pumping cost and increase production rate for artificial lift operations.


The advantage of our Swivel Coupling include:
Increase your Production Rate;
Increase Efficiency;
Decrease Rod Loadng;
Reduce Tubing Leaks;
Reduce Rod Failures;
Reduce Pump Repairs
etc.


Application. 
TR swivel sucker rod coupling can be used in all kinds of rod pumping wells. 

1, Prevent the sucker rod from thread off 
Connect TR swivel couplings in neutral point. It can eliminate sucker rods’ back off torque during reciprocation. This can greatly prevent thread-off.

2, Suitable for Liquid strike working conditions. 
Connect TR swivel coupling with the sucker rod above the piston. It can relieve the strong impact of bending moment. The liquid strike can be prevented when oil level is declined, the downhole tools and surface equipments damaged can be avoid, the sucker rod pumping cost can be reduced accordingly.

3, Suitable for Horizontal Well. 
TR swivel coupling can be connected with the sucker rods around yielding points. It can establish articulated juncture. This can prevent the eccentric wear, reduce friction and load of the ARTIFICIAL LIFT system. The maintenance-free operating period be can prolonged, the service life of pipes and rods can be extended, the electric power and cost can be significantly saved

4, Suitable for helical buckling of tubing 
TR swivel coupling can be connected with the sucker rods around helical buckling, Its articulated juncture can make sucker rods runs smoothly in helical buckling with best working conditions. It can provide pump-plunger overtravel and increase oil well production rate.

Using TR swivel couplings is a cost-effective and simple way to reduce sucker rod pumping cost and increase production rate for artificial lift operations. It can prevent sucker rod failures in above working conditions. The most cost-effective failure management starts from prevention. Using TR's swivel coupling is an idea way to stop the next failure/incident. TR’s swivel coupling can significantly save your cost and energy on rod string fishing, hanging and replacing.
