Abstract

The present design for ECT (Electrocoil Tubing) does not seal well fluid from the stuffing box if the tubing, BIW connector or any of the tech wire connections fail. The use of a Pack-Off that is attached to the tubing that ie exposed directly above the tubing hanger inside of the stuffing box will add a amount of redundant seal to the ECT system.
