Product Details

1.Insulation Joint/Insulating joint

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  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.

2.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

 

3.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

Air-tight testing pressure: equivalent to designed pressure

Non-destructive testing: All the butt-connectors are 100% ray-detected according to JB4730-94; other pressure welding
seams are 100% magnetic power detected.
