Tim Hurley, GPT Industries, USA, explains the differences between a standard gasket and an isolation kit, and the importance of properly installing them. As one of the world’s largest manufacturers […]
No one can argue that pipelines have changed tremendously in the last 75 years. Pipeline metallurgy has become stronger and less prone to corrosion. New exotic metallurgies have been introduced […]
Have you ever installed an isolating kit in a pipeline, successfully tested for electrical isolation, but later failed isolation following a hydrotest? .... Tim Hurley, GPT Industries, USA, explains the […]
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 […]
On a Flare Gas Recovery Unit, there are Carbon Steel flanges being bolted to A2205 Duplex Stainless-Steel flanges on the flare gas piping. As a result of the dissimilar metal, […]
A utility company operating out of the east of America approached GPT as they had encountered a leak and isolation failure following hydro-testing of their pipeline. The monolithic isolation joint […]
An operator of an established Oil field in the UAE approached GPT after encountering the same persistent problem with its flange isolation gaskets (kit) across two sites. Two years after […]
A multinational gases, technologies and services company was seeking an isolation solution for a pipe connection which had been prone to corrosion, the pipe carried Hydrogen and Nitrogen Gas, it […]
A global oil and gas operator was seeking a gasket solution for a new offshore platform that was to operate in the Gulf of Mexico. The large-scale offshore platform which […]
Pipeline operators based on the west coast of the United States started to notice that their flanges were beginning to experience shorts. Upon inspection it was identified that this was […]
A gas compressor manufacturer was looking for an insulation kit to be fitted to one of its compressors, located on an offshore platform within the Persian-Arabic Gulf. As the gas […]
An operator of an established Oil field in the UAE approached GPT after encountering the same persistent problem with its flange isolation gaskets (kit) at two sites. Two to three […]
Engineering firm had a refinery client that had a high temperature and pressure application that also needed to be fire rated.
An expansion device was being installed downstream of a control valve. This expansion device was made of SS316, while the upstream piping to the device was A106B, and the downstream […]
The ramifications of corrosion within the oil and gas industry can be devastating for many reasons. Not only is there the dramatic increased cost of replacement parts and components, it […]
This document is intended to take you through the differences between EVOLUTION® and VCS, to highlight why you may see EVOLUTION® quoted in addition to a standard VCS, giving you the option […]
With America’s pipelines aging and the ever increasing demands posed by harsher service conditions, the importance of integrity management and in particular corrosion prevention have never been more important and […]

Piping systems are utilised across the world to carry a multitude of different media such as oil, gas, water, chemicals and many other fluids and gases and are found in […]
A standard in gasket design for GPT is to match the gasket inside diameter to the pipe bore that the gasket is being put into. This is the appropriate sizing […]
You can now download GPT's highly acclaimed paper “New Design/Material Solution for Isolating Pipelines with Chemical and Permeation Issues”. The paper was presented at NACE CORROSION 2018, in Phoenix and […]
Robert Colton, Director of Product Management at GPT Industries, USA, offers his thoughts on how operators can maximise safety when dealing with extremely sour gas.
The selection and installation of isolation kits has seemed pretty simple throughout the years. Simply select a gasket that stated it was an “isolating gasket” and pair it with isolating […]
GPT has long experienced issues with Glass Reinforced Epoxy (GRE) based gaskets used in steam applications. The term, “steam,” used in the context of this article, is intended to be […]
In metallic pipelines, corrosion is the constant attempt by nature to reduce pipelines to their original oxide state. It is an electrochemical reaction that has four parts: anode, cathode, metallic […]
