Monolithic Insulating Joints are high-resistant fittings used to electrically isolate sections of a pipeline to improve the effectiveness of cathodic protection systems and to reduce ground-loop currents or interference between different CP systems.

​

These Joints can range from sizes ½” up to 120” and pressure classes ANSI 150 up to ANSI 2500. Zunt’s Monolithic Insulating Joints are provided with pipe pups matching the pipeline grade and wall thickness and are long enough to eliminate any possible thermal damage to the isolation components during field welding. Clients who wish to provide their own pup pieces for Zunt to assemble on to their joints may do so.

​

Monolithic Insulating joints are factory-assembled, hydrostatically tested and subjected to electrical tests in various stages of manufacturing . They do not require technical service or maintenance after installation.
