INSULATING JOINT AND CATHODIC PROTECTION MATERIALS

The insulating Joints is a new generation developed product to resolve use problems of old insulating flange. It is the essential pressure component necessary for steel pipeline cathodic protection system, broadly applicable to steel pipeline cathodic protection systems. Our companies insulating connectors 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, etc. The insulating connectors have realized buried parts maintenance-free function and allow a service life matching the pipelines
