GPT EVOLUTION INSTALL USES ZEVAC
A gas operator installing an 8in GPT EVOLUTION isolation gasket utilized ZEVAC to capture and recover vented gas. This made the operation emission free.
Gas operator installing 8 in GPT eVolution gasket UTILIZes ZEVAC TO MAKE THE OPERATION EMISSION free
Isolation gaskets are installed to protect lines from corrosion and unintentional leaks. Inmost cases, installing these gaskets requires sections of pipelines to be evacuated and purged, often by gas venting. The practice of venting creates intentional natural gas emissions, releasing methane into the atmosphere. It is a paradox to vent while protecting against leaks.
A gas pipeline operator in Pennsylvania needed to install an 8in GPT Evolution Isolation gasket at a well pad north of Pittsburgh. Instead of venting before installing and releasing emissions into the environment, they utilized ZEVAC services to capture and recover the vented gas. To draw down 200ft of 8in line from approximately 200 psi down to zero with ZEVAC took approximately one hour from set up to the point when the gas in the section had been re-compressed into an adjacent line.
Company personnel were then able to install the GPT EVOLUTION gasket. This gasket is fully encapsulated and just 1/8in thick for easy installation. The GPT EVOLUTION is extremely abrasion and impact resistant due to the proprietary coating. It is also fire safe and does not have lamination.
This project protected their pipeline and protected the environment.

GPT Preventing Electrical Bridging in Pipeline Isolation Joints
These resources help Oil and Gas operators meet the increasing demands and conditions such as sour gas.
In today’s Oil and Gas industry, increasing demands and conditions have become commonplace and are only set to continue as operators maximize and improve efficiencies in their processes. The increase in sour gas is one such example. Increased sour gas percentages are being experienced across the globe, presenting unique challengers to pipeline operators.
Sour gas can interact with moisture in pipelines and the metallurgy in the pipe to create Iron Sulfide known as “black powder”, a conductive material that can bridge isolation joints.
CASE STUDY: Overcoming Electrical Bridging with EVOLUTION®
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 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.
