CoRE FEATURES

DESIGNED FOR LONG-TERM PIPELINE SERVICE

Robust Mechanical Strength

Designed to withstand high bolt loads while maintaining sealing integrity.

Excellent Torque Retention

Resists relaxation and creep under sustained compression.

Steam & Fluid Compatibility

Suitable for steam, oils, water, fuels, and general industrial media.

Dielectric Performance

Demonstrates good electrical insulation properties for isolation-sensitive applications.

Product information

Configured for Fit, Pressure & Performance

Engineered to match pipeline dimensions and pressure ratings, providing permanent electrical isolation through a fully welded, maintenance-free pipeline assembly.

Types

PG 20

Matches pipeline diameter, wall thickness, and pressure rating without structural compromise.

PG23

Provides permanent electrical separation to support effective cathodic protection systems.

PG GL

Maintains isolation and structural integrity throughout long-term pipeline service.

PG R

Installs directly into pipelines through welding, eliminating flange joints and maintenance.

PG MASTERCHEM

Installs directly into pipelines through welding, eliminating flange joints and maintenance.
Benefits
