The insulating joints have realized buried parts maintenance-free function and allow a service life matching the pipelines.
The insulating joint is the essential pressure component necessary for steel pipeline cathodic protection system, broadly applicable to steel pipeline cathodic protection systems, adopts a unique design based on referencing foreign latest product structure to overcome problems of inadequate rigidity, prone to leak, unable to be buried under ground short service life, ete.
