The Insulating Joint 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 companys 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. 

Technical characteristics:

 

Pressure grade:PN1.0-PN40MPa

Service life:same as the service life of pipeline

Ambient temperature:-30°C-90°C

Applicable medium: oil, gas, water, chemical feed, mineral slurry

 

Quality requirement:

 

Insulating resistance value≥10MΩ @DC1000V, Maximum voltage:≥3KV

Insulating intensity: no breakdown or arc for one minute @2500V 50Hz

Hydraulic pressure testing pressure: 1.5 times of desingned pressure
