Aside from exhibiting at the summit, the company will present a technical paper, “Development of new generation of Seat Seals for Cryogenic Trunnion Mounted Ball Valves” on the morning of May 24. Covering a wide range of sizes and pressure ratings (up to 20” and 2500LB), cryogenic trunnion mounted ball valves are critical components in the LNG supply chain because they need to provide reliable, bubble-tight sealing. Since valve performance is strictly governed by several industry standards, manufacturers of cryogenic trunnion mounted ball valves are struggling to meet the global seat leakage requirements specified in a majority of these stringent standards using current sealing solutions available.
In order to support customers with future performance requirements concerning engineered valves such as the above ball valves, Saint-Gobain Seals has instituted a pre-validated design process where their engineering department optimizes polymer spring-energized seat seal designs using Finite Element Analysis (FEA) virtual testing and an internal testing campaign. Part of this process includes research and development investment toward application testing capabilities (e.g., fugitive emissions, HPHT and cryogenic). By implementing pre-validated design, they are able to develop solutions that have a precise fit for their customers’ requirements, leading to reliability over lifetime of the sealing solution.
Although Saint-Gobain Seals will focus on sealing solutions for LNG production and transport at the Industrial Valve Summit, they also have been supporting oil & gas customers who work with deep and ultra-deepwater production, harsh chemicals, rapid gas decompression resistance, extreme temperature and sour gas concentrations. Some of their sealing solutions include proprietary Fluoroloy® fluoropolymer compounds qualified to NORSOK M-710 and to API 6A F.1.13 specifications; metal energizers NACE MR01-075 approved alloys for use in sour gas service and cryogenic temperatures; and designs compliant with Low Fugitive Emission international standards ISO15848 and Shell MESC SPE 77-312.
