What Are Torque Rings?

Torque rings can revolutionize the way you run, rotate, and reciprocate API pipe. Now, while you may have heard of torque rings before, you may not be sure what they do. Here are the answers to three major questions regarding torque rings, explaining both what they are, and how they can improve your drilling operation.


What Is a Torque Ring?

Torque rings, which range in size from two-and-three-eighths inches to 20 inches, let you run, and rotate API pipe at torques that often exceed semi-premium, and premium connections. A torque ring is like a normal connection, but it has a buttress or LTC-threaded outer diameter that lets it lock into the "J” space of the collar. Due to the simple change of the added torque ring, the positive shoulder lets you reach higher torque values, and extends your thread life while running operations. This positive shoulder makes positional makeup obsolete, and gives you a sound connection you can rely on. Specifically, the torque ring optimizes your performance just like a premium connection does, but costs significantly less.

How Do Torque Rings Operate?

When the pin hits the centered ring, the torque ring acts as a jam nut, rotating the collar if necessary. This function gives you a centered, and balanced connection. The greater the torque, the greater your ability to get through tight spots, hitting your target depth in casing operations. Additionally, you can rotate with torque rings during the cementing phase, which can offer you better cementing, and optimized production.

What Should I Be Looking for When Buying a Torque Ring?

There are a few torque ring features that maximize their benefits:

  • A threaded OD produces up to two times the torque yield of torque rings that conform to collar threads. When you’re searching for a torque ring, you want to find one with a threaded OD. This treading gives you a greater cross sectional area, and 100% metal engagement.
  • A circular, non-stressed design makes a torque ring stronger, and better able to handle stress than torque rings with oblong shapes.
  • A torque ring made of P-110 or greater rated steel, with API specifications, is more durable than torque rings made from L-80 grade tubing.
  • A torque ring that can be installed on location before the job without special tools makes your workload that much easier. Some torque rings require handheld hydraulic tools to compress the ring into the collar, but torque ring tools are not necessary.
  • A smooth ID should be on your torque ring to mitigate the risk of collar failure due to washout. While traditional API piping can’t protect against this failure, a smooth ID covers exposed threads.
