4 . 5 METAL AND PLASTIC PIPES
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 eect. Use the grounding
rings on both ends (see Fig. 50).
