Insulating Flange Assembly

We offer a comprehensive range of zero leak-High performance Insulating Flange Assemblies engineered to meet the varied needs of industrial applications. These assemblies are specifically designed to electrically isolate sections of piping systems while maintaining a secure, pressure-tight seal with a design of handling pressure from 2175.57 to 36259.43 psi and sizes up to 100 inches in diameter.

They are essential components in electric isolation in cathodic protection systems, pipelines that transport corrosive or conductive fluids, and applications where galvanic corrosion must be prevented—particularly when joining dissimilar metals. Our insulation flange assemblies help extend equipment life, enhance safety, and support long-term system integrity.

OUR BENIFITIES

Monolithic Isolation Joints (MIJs)

Monolithic Isolation Joints (MIJs) are factory-assembled, weld-free devices designed to provide electrical isolation in pipelines. They are a crucial component in cathodic protection systems, ensuring the long-term integrity of the pipeline by preventing stray current corrosion and electrical interference between different sections of the pipeline.

Specifications:
  • Pressure Ratings: From 150 psi up to 2,500+ psi
  • Temperature Range: Typically -20°C to +120°C
  • Available: From ½" to 48" and larger
  • Electrical Isolation Resistance: >10⁶ Ohms
  • Dielectric Strength: >5 kV
  • Body: Forged or welded carbon steel From ½" to 48" and larger
  • Insulating Material: High-dielectric strength epoxy, phenolic resin, or reinforced polymers
  • Coating: External anti-corrosion coating
