Traveling Joint (SP Lined)

Expansion Joint

The Expansion Joints are designed to be used in single and dual - string completion to accommodate changes in tubing length caused by variations in pressure, temperature or both and reduce the chances of over stressing the well tubing during production, acidizing, fracturing and other well operations. A honed alloy-steel cylinder gives these joints good dynamic sealing performance as well as high body and end-connection burst, collapse and tensile strength. Splined piston can transmit required make up and shearing torques.
