GPT Isolation Gaskets – Matching to the Pipe Bore
Guide to understanding sizing for GPT Isolation Gaskets. A standard in gasket design for GPT is to match the gasket inside diameter (ID) to the pipe bore that the gasket is being put into.
A standard in gasket design for GPT is to match the gasket inside diameter (ID) to the pipe bore that the gasket is being put into. This is the appropriate sizing for most GPT gaskets.
GPT Isolation Gaskets
The flange bore will directly depend on how the flange connects to the pipe, and in general there are two ways – Weld Neck and Slip-On. Weld Neck typically means the flange is butt-welded to the pipe and in this case the flange bore will match that of the pipe bore. Slip-On means the flange is designed to slip over the outside of the pipe where it is then welded in place and therefore the flange bore will be slightly bigger than the outside diameter (OD) of the pipe. Knowing the type of flange is the first step to understanding the ID of the gasket needed. The goal is for the gasket ID to match the flange bore.
For a given nominal pipe size, the OD of the pipe does not change, but the pipe schedule changes and is related to the wall thickness (WT). The larger the schedule the ticker the pipe e.g. SCH 10 is thinner than SCH 80.
The gasket ID with a slip-on flange will be slightly bigger than the standard OD of a given nominal pipe size. For a weld-neck flange, the flange bore is the same as the pipe bore.
Wrong Sizing Leads to Corrosion & Erosion
It is important to understand why the gasket ID is required to be equal to the flange bore. For example, if the gasket ID was sized larger than the flange ID, the flange face and isolation would be at an increased risk as there would be a void between the two flanges causing increased turbulent flows of media. This increased turbulence can lead to crevice corrosion. There would also be an increased risk of unwanted media build ups in the void which could cause an electrical bridge shorting the path of isolation.
If the gasket were to be sized smaller than the flange ID, then the gasket would be protruding into the pipe, there is a risk of the sealing element landing inside the flange bore and not sealing against the flange face. The gasket would also be in the direct path of the media and pigs (both the pig and the gasket could be damaged). This situation again would cause increased turbulent flow leading to corrosion and erosion.
In the case of matching two flange faces with different bores, GPT best practice is to match the gasket ID with the larger flange bore.
In summary, matching the gasket ID to pipe bore is the effective way to mitigate corrosion and maintain electrical isolation.

PIPES ACT 2020 Inspection & Maintenance
These mandates require pipeline owners and operators to update their inspection and maintenance plans in order to address eliminating hazardous leaks and minimizing the release of natural gas from their pipeline facilities.
The PHMSA PIPES ACT 2020 mandates pipeline owners and operators to update their inspection and maintenance plans in order to address eliminating hazardous leaks and minimizing the release of natural gas (including intentional venting during normal operations) from their pipeline facilities. The statute requires pipeline operators to complete updates and have plans in place.
Have you implemented the PIPES ACT 2020 into your operational procedures?
Are you implementing set plans to reduce emissions when carrying out pipeline maintenance and repair projects?
Kerr Engineered Sales Company represents manufactures with multiple proven solutions to reduce emissions and assist in leak detection and repair.
Reducing Emissions With GPT
With gaskets and joints, seal ability is key. The VCS-ID gasket constructed of Glass Reinforced Epoxy (GRE) and a 316SS, has a PTFE (polytetrefluoroethylene) inside diameter (ID) immediately seals the pipe bore preventing media from getting to the GRE. The GPT Monolithic Isolation Joints for below ground pipe applications gives a positive, leak proof block against the flow of electrical current in the piping system.
The EVOLUTION gasket eliminates GRE completely. It benefits from the addition of the PTFE ID giving unparalleled sealing tightness performance, ideal for emission reduction in pipeline connections.
BRUEST CATALYTIC HEATERS
Bruest offers catalytic converters that convert hydrocarbon such as Methane, Propane, and Butane to carbon dioxide and water vapor. The Bruest technology leverages the conversion process and generates infrared heat to safely heat up natural gas instruments such as valves, regulators, instrument gas and cold temperature sensitive devices.
ZEVAC = Zero emission vacuum & compression
ZEVAC is an industry pioneer in gas and liquid recovery technology and the recognized leader in methane mitigation applications. ZEVAC is ideal for reducing emissions on planned repairs or maintenance. The technology uses compressed air to draw the pressure down on a section of the pipe and capture natural gas to be re-compressed into an adjacent pipeline.
Each unit has a pneumatic powered vacuum that suctions methane from any pipe/vessel that needs to be de-pressurized.The other side of the ZEVAC unit compresses the gas back up to pipeline pressure so it can be discharged to a nearby transmission or distribution pipe.
GAZOMAT GAZOSCAN METHANE LEAK DETECTION
GAZOMAT Gazoscan methane leak detection
Using optical technologies, GAZOMAT detection equipment covers the entire field detection process, including high-speed inspection by car, leak detection on-foot, leak location and quantification, coupled with the newest data processing and GPS mapping tools.
TDW Pipeline maintenance
T.D. Williamson hot tapping and plugging teams use world class technology to create safe work zones for pressurized pipeline maintenance, modification and repair. TDW in-line inspection (ILI) technologies are fully engineered to provide comprehensive threat assessment and to detect cracks and crack-like anomalies, corrosion and metal loss, dents and interacting threats.
