New FKM ma­te­rial specif­i­cally to meet the de­mands of the oil and gas in­dus­try

Chemical Industry Digest - - Products & Processes -

C.Otto Gehrck­ens’ newly de­vel­oped FKM com­pound Vi 900 is a high-per­for­mance prod­uct in­no­va­tion for use in the petro­chem­i­cal in­dus­try. The ma­te­rial has proved its suit­abil­ity as a de­pend­able elas­tomer seal even un­der the most de­mand­ing con­di­tions, com­ply­ing with NORSOK test stan­dard M-710 and also pass­ing the hard­ness test with the best pos­si­ble rat­ing of 4x ‘0000’, with­out show­ing any dam­age what­so­ever. Vi 900 is there­fore ideally suited for use in pro­duc­tion sec­tors which, as a re­sult of the dan­ger of ex­plo­sive de­com­pres­sion, im­pose es­pe­cially high de­mands on the seals used.


out­stand­ing ❍ sta­bil­ity un­der low tem­per­a­tures.

With a TR-10 value of -40°C, Vi 900 is suit­able for the cold­est ap­pli­ca­tions, right down to -50°C and It com­plies with the NORSOK stan­dard, it there­fore also com­plies with Amer­i­can stan­dards API 6A and 6D for oil and gas in­stal­la­tions.

It is com­bined with an ex­traor­di­nar­ily good cold com­pres­sion set.

The ma­te­rial sets new stan­dards in re­la­tion to AED (anti-ex­plo­sive de­com­pres­sion) and RGD (rapid gas de­com­pres­sion) seal ma­te­ri­als.

A fur­ther plus point for this new FKM com­pound is its ex­cel­lent re­sis­tance to a wide range of spe­cific me­dia and chem­i­cals, from min­eral oils to aliphatic, aro­matic or even chlo­ri­nated hy­dro­car­bons and also to acids in var­i­ous con­cen­tra­tions and weak al­ka­lis. And as the ma­te­rial is also char­ac­ter­ized by very low gas per­me­abil­ity, a wide range of ap­pli­ca­tions is pos­si­ble. Vi 900 is used as a seal ma­te­rial in valves, ball cocks, pig traps or slider valves in pro­duc­tion ar­eas where the very high­est lev­els of re­li­a­bil­ity and the best pos­si­ble qual­ity with re­spect to ex­plo­sive de­com­pres­sion are re­quired, above all in the petro­chem­i­cal in­dus­try, in com­pres­sor con­struc­tion and also in com­pressed air prepa­ra­tion.
