In most completions, the length of tubing available at surface is not enough for proper wellhead installation and operation. Pup joints and varying lengths of tubing are used to adjust the production string length as close as possible to the desired value. Then, the adjustable union or joint is installed, rotationally adjusted, and locked to the desired makeup length. In dual completions, the tool can be used to adjust the length of the short string.

The adjustable, telescoping action of the union or joint allows it to be set and locked at any desired position within its adjustment length while maintaining pressure integrity in the tubing string. Once the tool is in place, the desired amount of tension, weight, and rotational torque can be applied through it to the tubing.

The design of the NPST pup joint takes end connections and attaches them to threaded pipe. The quality of these parts is critical to form and function. The process is designed for a seamless integration between pipe and union. It’s hard to tell where one part begins and the other ends.

With customizable options, our plugcatchers are rated for 10,000 or 15,000 CWP. Depending on your requirements we can use different styles of crossovers and pup joints to get the solution you need. We test every one of our plugcatchers at time and a half CWP before they ship.
