Natural gas filter „FYG” type July 2011
NATURAL GAS FILTER „FYG” TYPE
APPLICATION: The natural gas filters FYG type are used to filtrate natural gas in the medium and low pressure installations .
E&P = Exploration & Production T = Transportation S = Storage D = Distribution
CONSTRUCTION: The body and top of the filter are made of cast iron. The
filtering cartridge is manufactured from sieve for finesses of 160µm and viledon sieve for
finesses of 10 µm. According to the connection it is manufactured in two types: - thread connection for DN ≤ 32 mm - flanged connection for DN > 32 mm OPERATING PRINCIPLE: The gas enters the filter’s body through the inlet connection, passes through the filtering cartridge which retains the particles existing in the gas flow, then exits the filter through the outlet connection.
