NOTE
• Particularly close attention must be paid when
installing the product in the pipeline with
cathodic protection. Isolate it from the pipeline
by installing isolation bushings and washers
on the bolts of the flange and connect a wire
between the pipes, large enough to handle the
cathodic current and the environmental effect.
Use of the grounding rings on both ends. See
fig_4_7 on the next page.
