An oil and gas operator located in Australia approached GPT Industries as they were encountering an issue with two flange connections that were experiencing leakage issues within hours of installation. On closer inspection it became clear that the leakage was not coming from the flange face but was in fact a result of the media permeating through the body of the gasket.

A long-established midstream oil and gas operator had been experiencing long term issues with Phenolic isolation gaskets. They approached GPT seeking a solution that would give them longer service life at several compressor stations with differing pipeline sizes, ranging from 4” to 20”NPS.

The issues encountered came as no surprise to GPT, Phenolic insulation gaskets have been persistently plagued by several failure modes.
Namely: embrittlement, permeation, poor dielectric values, electrical bridging and cracking due to over torquing.

GPT_EVO_Electrical Bridging_06.2022(F)A problem that is becoming more and more common place in industry is electrical bridging. For years, this customer has battled losing isolation across the flange isolation kit, not because of a gasket failure or mis-installation, but instead because of the media itself but instead due to the media itself going through the line. In these lines, solid conductive deposits build up at the flange intersection, allowing CP current to take this path, jumping the isolation kit, and continuing to the next flange.

Tim Hurley, GPT Industries, USA, explains how fiberglass reinforced epoxy products can be used to prevent galvanic corrosion in flanged piping systems.

GPT is proud to announce the relaunch of the ElectroStop® Monolithic Isolation Joint with expanded large MIJ manufacturing capabilities.

GPT has invested in new manufacturing equipment allowing for the production of the ElectroStop® up to NPS 48 in Houston, TX USA. With the ability of manufacturing up to 48” ANSI 900# ElectroStops, and the complimenting ElectroJoint™ product line for smaller diameter MIJ’s, GPT has the ability to supply a full range of isolation joints for the Oil & Gas Market.

GPT expanded the manufacturing cell from 6,500 sq ft to 10,200 sq ft, and added new equipment including a Miller Sub arc welder, phased array ultrasonic testing (PAUT), large welding booth, a 5 ton overhead crane, material handling equipment, and a 250 ton hydraulic press for Large MIJ assembly. The expansion of the production area with the additional equipment will significantly increase capacity, and the efficiency of production of all sizes.

To illustrate the many, varied uses of GPT pipe solutions across entire industries – and to help visitors identify the solution that’s right for them – we’ve created two new dynamic displays on our website that show the applications for GPT products throughout the Oil and Natural Gas production processes. Both displays follow the development path beginning at wells and platforms, moving through processing, transportation, storage and finally, to the end user, highlighting commonly specified products at each stage in the journey.
