Monolithic Isolation Joints and Isolating Flanges for Pipelines

GPT engineers and manufactures a range of high quality sealing and isolating products used to ensure the safe flow of fluids in transmission, distribution and process piping systems. Flange isolation products include a wide selection of isolation joints and spools that are available in all pipe sizes, types, pressure ratings, and materials.


ElectroStop® Monolithic Isolation Joints

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.

ElectroJoint™ Monolithic Isolation Joints

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

ElectroFlange™ Pre-Fabricated Isolating Flanges

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.

ElectroSeal™ Monolithic Isolation Joint

ElectroSeal™ MIJs eliminate short-circuits, field assembly, and are protected from corrosion by internal and external coatings. The ElectroSeal™ MIJs come with a unique U-Sealing design, which provides a dynamic sealing structure to protect it from potential leakage due to pressure fluctuation within the pipeline.
