Isolation Joints

trenton wax tape products


Factory assembled, permanent and maintenance-free weld-in electrical isolation joint. Replaces flanged connections.

The ElectroStop® monolithic isolation joints are a leak-proof, maintenance-free and long lasting block against the flow of electric current in all piping systems. The ElectroStop® eliminates short circuits and field assembly. The ElectroStop® is coated internally and externally to prevent corrosion and is 100% hydrostatically, electrically and weld tested. All ElectroStop® monolithic isolation joints are manufactured under an ISO Quality Management System.

GPT’s new ElectroJoint™ monolithic isolation joint (MIJ) is a maintenance-free alternative to flanged pipeline connections appropriately sized and priced for gas distribution lines.

The ElectroJoint™ MIJ eliminates the risk of failure due to improper field assembly of traditional flange components by providing a complete coated isolation system that simply requires two butt welds on either end of the joint for installation.

The ElectroJoint™ MIJ is manufactured, individually weld-inspected, and hydrostatically tested under an ISO Quality Management System.

The availability of the ElectroJoint™ MIJ means even more of these pipeline integrity problems caused by human error can now be cost-effectively prevented.

The ElectroFlange™ is a pre-fabricated flange isolation kit including the flanges, bolts and pipe pups

ElectroFlange™ Joints provide electrical isolation for gas, water and petroleum pipelines; providing operation and maintenance cost savings. They do not require maintenance and can eliminate vault expense. GPT offers the best solutions for preventing corrosion in all industries including: onshore and offshore mains, petroleum refinery complex, chemical plants, waterworks, wastewater, gas transmission and gas distribution systems.

The ElectroFlange™ is factory assembled by GPT under controlled conditions and is 100% factory-tested and warranted to meet customer specifications for size, pressure, corrosion coatings etc. Available with a NSF-61 Certified interior coating.
