RING JOINT GASKETS
RTJ gaskets are produced in different solid metal types. They are used for high pressure (till 1300 bar) and for high temperature (till 1000°C) and are used where corrosive agents are presents. These gaskets are obtained by mechanical working from forged or laminated metals. RTJ find their mainly application in refining process in crude extraction and in high pressure applications. For their production we use the last edition of the API standard. FMI can supply oval and octagonal ring joint, BX and RX for all applications to suite the flanges design with standard and special styles.
