Monolithic Insulating Joints

Monolithic Insulating Joints are used for electrically isolating of cathodic protected pipeline sections from unprotected pipelines or other metallic structures.

Monolithic Insulating Joints are maintenance free, boltless, rigid pipeline components, factory-welded and ready for installation at site. They are suitable either above or underground installation without the need for special precautions.

Monolithic Insulating Joint:

Eliminates short circuits, bolts, sleeves and washers – the major source of short circuits in most isolation assemblies – are eliminated with isolation fitting.

 Eliminates Field Assembly, isolation fitting is completely factory assembled and tested. There are no flanges, gaskets, nuts, bolts, sleeves or washers to handle and consequently no fluid leaks due to improper field assembly.

 Less Expensive

Purchase the isolation fitting for less than the cost of the component parts of  insulated flange assemblies in most pipe sizes. Install the isolation fitting for less  than the labor costs of installing an insulated flange assembly.

 Please provide the following information on any request for quotation:

  • nominal pipe size
  • pipe wall thickness
  • pipe grade
  • design rating or pipeline pressure
