4.6 PIPES EQUIPPED WITH CATHODIC PROTECTION
Particular 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 the grounding rings on both ends (see Fig. 50).
