Hello! At what distance from the gas pipeline, grounding must be mounted?
The vertical electrode with the depth of more than 5 meters, "works" on 90% - in the zone around itself of a radius equal to its depth.
At the distance of 2 depths, there is a 95% working area of such an electrode.
Zone of 99% efficiency of such an electrode is within the range of 20 depths.
Thus, it is reasonable to place a vertical grounding electrode at the distance of an electrode double depth.
However, when you connect lightning protection (lightning rods) to the ground electrode, this distance should be increased up to 5-fold size.
Let me draw your attention that the great separation of the pipeline electrode is only necessary in cases of possible presence of serious power currents (eg, lightning currents - when connecting grounding electrode (s) to a lightning rod).
