Systems and methods for efficient on-line pigging of a coker furnace without interruption of the delayed coking process, which will save time and money during the delayed coking process. This system can be retrofitted to existing coker furnaces.

The present application concerns in-situ intrusive probe systems and methods. The probe systems described herein can be installed flush to a hydrocarbon containing structure, such as a pipeline, vessel, or other piping system carrying crude, gas or sour products. The probe systems include hydrogen induced cracking (HIC)-resistant microstructure such that as atomic hydrogen permeates the probe surface, the probe captures recombined hydrogen gas. The pressure of the resultant hydrogen gas buildup is measured and predictions as to the HIC activity of that area can be made.
