ElectroJoint™ Monolithic Isolation Joints

Jump To Section:

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.

Additional Information

Eliminates Short Circuits

Bolts, sleeves and washers — the major source of short circuits in most isolation assemblies — are eliminated with the ElectroJoint™ monolithic isolation joint. Each joint is electrically tested during production to assure integrity, performance and isolating properties to protect against dielectric and galvanic corrosion.

Eliminates Field Assembly

The ElectroJoint™ isolation joint is completely factory assembled and tested. There are no flanges, gaskets, nuts, bolts, sleeves or washers to handle and consequently no fluid leaks due to improper field assembly.

100% Hydrostatically Tested

All ElectroJoint™ MIJs undergo a hydrostatic test at 1.5x MAOP in accordance with ASME B31.3 standards.

Completely Weld Inspected

The integrity of each weld is verified utilizing magnetic particle inspection.  All ElectroJoint™ joints are manufactured under an ISO Quality Management System.
