EGCR 2023 Marks 50 Year Kerr Legacy
Join the KERR team May 2-4, at Booth # 408 at the 2023 Eastern Gas Compression Roundtable (EGCR) in Pittsburgh, PA. David Kerr, 2023 Chairman of EGCR, is continuing a fifty year legacy of Kerr Engineered Sales and EGCR collaboration.
EGCR- May 2-4 David L. Lawrence Convention Center
Join David Kerr and Nigel Belshaw May 2-4 at Booth # 408 at the 2023 Eastern Gas Compression Roundtable (EGCR) in Pittsburgh. EGCR is a non-profit organization whose primary purpose is to provide the Natural Gas Industry with cost effective training programs focusing on engine and compressor maintenance. Countless operators, engineers, gas pipeline managers, industry leaders and insiders have gone through EGCR training.
One of the most popular tracks is the Entry Level Compressor Station Operator Training which focuses on the basics for those new to the industry including: yard piping, auxiliary systems, prime movers, compressor components and operating characteristics of reciprocating and centrifugal compressors.
ZEVAC Session: Compressor Unit and Station Maintenance without Blowdowns
ZEVAC MINI
Doug Sahm, PE, from ZEVAC, is leading a session Tuesday afternoon for Compressor Unit and Station Maintenance without Blowdowns. ZEVAC: Zero Emission Vacuum & Compressor is answering the call to eliminate blowdowns from compressors and compressor stations with new D3 technology that doesn't require any external power source (runs on station dP) and allows closed-loop design of the stations so that they are future-proofed and avoid any current or future methane penalty costs.
50 Year EGCR & KERR Legacy
David Kerr, Kerr Engineered Sales CEO is the Chairman of EGCR for 2023. David is continuing a fifty year legacy of Kerr Engineered Sales and EGCR collaboration. The first EGCR Roundtable was held in 1973 at West Virginia University. David’s Father, Arthur J. Kerr, Jr, President of Kerr Engineered Sales Co. was one of the early pioneers that led industry discussions addressing the need for training and support to address operating and maintenance for compressor systems.

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.
