CE Dual Action CT Spring Jare
The CE Dual Action CT Spring Jar enables repeatable upward or downward jarring blows to the work string.
The amount of tension or compression placed on the coiled tubing in order to fire the jar is dependent on the amount of preload force placed into the jar springs, which is adjustable at the surface.
The release loads are relatively light, typically from 1500 LBS to 5000 LBS, depending on the Jar O.D. size. As there is no hydraulic fluid chamber inside the Jar, it is susceptible for high temperature. It has an increased impact ratio and requires very little force to re-cock.
The CE Dual Action CT Spring Jar is simple to operate and redress. A calibration tool is available in order to perform a surface test for the Jar release load.
