Analysis of Differences in Design and Construction Standards for Cryogenic Liquefied Gas Storage Tanks between National and European Standards
Russia and Central Asia have emerged as significant overseas chemical markets for China in recent years.Chinese company has been involved in numerous chemical projects in Russia,including cryogenic liquefied gas storage tank projects.The Russian standard for cryogenic liquefied gas storage tanks is based on the European standard system.In order to better promote liquefied gas storage tank projects in regions where Rus-sia and the European standard system are used,based on a specific eth-ylene cryogenic storage tank project currently under construction in Rus-sia,this paper analyzes the differences between the national standard GB/T26978-2021 and the European standard EN14620-2006 in terms of design and construction requirements for cryogenic liquefied gas stor-age tanks,including material selection,wall thickness requirements,im-pact test requirements,chemical composition,manufacturing require-ments and pressure test replacement.The comparative analysis results can provide a reference for Chinese contractors undertaking cryogenic liquefied gas storage tank projects in Russia and regions where the Rus-sian and European standard systems are applied.
