The EASC or Euro-Asian Council for Standardization, Metrology, and Certification is a standards organization that works under the CIS or what is referred to as the Commonwealth of Independent States. As a regional standards organization, they maintain a set of technical standards known as GOST (ГОСТ in Russian). The term GOST is an acronym, which literally translates to governmental standard in English. A standard that deals with flanges are GOST 12821. The GOST 12821 Flanges are constructed in stainless steel and are used across different fields.
From being used in water piping systems to natural gas industries, oil fields, and offshore oil industries, these flanges are a popular choice. Depending on the stainless steel grade, these GOST 12821-80 RTJ Flanges may also be used in marine engineering and electric power plants because of their superior corrosion resistance properties. Being the most stressed out of all the other types of flanges, the use of stainless steel GOST 12821-80 Blind Flanges is to form either permanent or temporary seals. They could be used in piping systems, valves, pumps, etc because they are strong. Yet, the stress they withstand is very high. By forming a block in piping systems, the ГОСТ 12821 Blind Flange absorb the vibrations and shocks that are a result of a forceful flow. Aside from blind and weld neck flanges, another popular variety is the threaded type. Unlike the other two that use welds or bolts for connection, the GOST 12821-80 Threaded Flange depends on the internally carved threads to forge connections. Ductile materials form the best threads. However, apart from having good ductility, a material must also have good toughness to prevent the damage caused on the internal threads of the threaded GOST 12821-80 Stainless Steel Flanges.
