Supply of Monolithic Joints

🛡️
Total Isolation

📏
High Strength

⚡
No Maintenance Required

We supply high-performance monolithic joints for the electrical isolation of underground or overhead pipelines. Our joints eliminate the need for isolating flange kits, ensuring a permanent airtight seal and zoned cathodic protection.

Description

Validated Experience: Technical services in accordance with international standards (ASME, API, and NACE) for permanent electrical isolation for fluid transport infrastructure.

Service Description

The supply of monolithic joints by TECNA ICE addresses the need to permanently isolate sections of pipeline, preventing the leakage of cathodic protection current to unprotected or grounded structures. Unlike traditional isolating flange systems, our monolithic joints are single-piece devices, pre-assembled and factory-tested to withstand high pressures and mechanical stresses without requiring retightening or subsequent maintenance. Their design ensures superior dielectric strength, even in conditions of high humidity or aggressive soils.

Technical Specifications

Diameters ranging from 2“ to 48” (upon special request).
Pressure classes ANSI 150 to 2500.
High-strength epoxy coating for both interior and exterior surfaces.
Certified hydrostatic and dielectric tests.

Operational Benefits

Prevention of accidental electrical short circuits.
Cost savings on maintenance and package replacement.
Structural integrity equivalent to that of the base pipeline.
Efficient zoning of cathodic protection systems.

Isolation Warranty

Every monolithic joint supplied by TECNA ICE comes with its own quality dossier, detailing the electrical insulation tests and non-destructive testing (NDT) performed on the internal welds. This level of quality control ensures that electrical isolation is effective from day one, facilitating potential measurement tasks and guaranteeing that the induced current remains confined to the section in question.
