3 10 REASONS TO USE FLEXIBLE GRAPHITE Thanks to its structure, which provides it with the remarkable properties described below, the primary use for flexible graphite is in the sealing sector. Compressibility: Flexible graphite can be compressed to a maximum density limit of 2.25 (ratio between mass & volume). The choice of initial densification is a major factor in the optimization of the final product s characteristics. Resiliency: Flexible graphite has a capacity for resiliency of about 10% in volume, making it possible to maintain seal performance over a broad temperature range. Creep/relaxation: Flexible graphite has a very low creep rate in its service temperature range and holds up to high pressures. Temperature resistance: In a reducing or inert atmosphere, flexible graphite retains its characteristics over a broad range of temperatures, from -196 C to 2500 C ( F to 4532 F) (sublimation temperature = 3500 C/6332 F). In the presence of oxygen, graphite forms CO or CO 2 from 500 C to 550 C (932 F to 1022 F) upwards for high temperature grades. The speed of oxidation depends on the surface in contact with the oxidant object. Aging: Flexible graphite is one of the non-metallic materials that is least affected by aging. This property is not influenced by temperature. Radiation performance: Flexible graphite resists aging from high levels of radiation: no visible effect at neutron/cm 2. Chemical inertness: Flexible graphite, which contains no binders, withstands most chemicals, such as mineral acids and solvents. Lubrication: Flexible graphite is self-lubricating and has a low coefficient of friction (less than 0.10 with steel). Processing: Flexible graphite is easy to cut using conventional manufacturing equipment/techniques. Removability: Flexible graphite adheres very little on sealing surfaces. 3

7 ORIGRAF SEALS CONCEPT AND ADVANTAGES OF ORIGRAF SEALS Recommendations for use The ORIGRAF, an expanded graphite seal, is created from strips of CEFIGRAF flexible graphite, densified under pressure using special equipment. The seal is obtained through the final densification of the seal when it is tightened in contact with the mechanical stop (also known as metal-metal contact). The metal-metal contact is obtained: either by assembling a graphite ring in a groove or by the insertion of a graphite ring between interior and/or exterior rings which serve as tightening limitations. Advantages of metal-metal contact: it consists of creating a rigid mechanical contact independent of the active part of the graphite seal which is thus preserved against the general mechanical assembly constraints. The resiliency of the seal only serves the sealing function. This metal to metal concept also allows the seal to be protected from over-tightening. ORIGRAF seal with anti-extrusion cups ORIGRAF seals can be equipped with anti-extrusion cups. These make it possible to avoid the extrusion of graphite during the tightening phase, ensuring a targeted densification. This concept (patented system) is recommended in the following cases: high pressure large space between metallic assembly parts highly corrosive fluids or fluids with high levels of impurities, to protect the center of the seal MAIN ADVANTAGES OF ORIGRAF SEALS Excellent elastic recovery, capable of reaching 50% of compression. Very good endurance in thermal transients No marks on the sealing surfaces, making maintenance easier when opening the flanges and replacing the seal Good resistance to radial movements of the flanges Excellent ability to withstand a wide range of temperatures: -196 C to C ( F to F) (in an inert environment and according to the assembly conditions) Fire resistant Very low level of relaxation (6 to 8% max.)

Seating pressure: numerous tests on the characterization of the ORIGRAF seals have made it possible to master the essential settings linked to the seal's performance. This enables us to retain a seating nominal pressure of 3.5 to 5 MPa for the majority of applications.

11 ORIGRAF GASKETS FOR STANDARDIZED FLANGES APPLICATION AREAS FOR ORIGRAF SEALS ORIGRAF ON 002 gaskets have been designed for adaption to flat surfaced flanges (type FF) or raised flanges (type RF) and single insertion (type SE), following flange standards NF-EN and NF-EN (ASME/ANSI B16-5). Gaskets with specific dimensions have been defined for each type of flange (please contact us). USAGE RECOMMENDATIONS Surface condition of the contact areas: - rounded surfaces: the contact areas must have a flat surface made up of either: Ra=0.8 to 12.5 µm for circular seals (recommended Ra = 1.6 to 6.3 µm) Ra= 0.4 to 1.6 µm for shaped seals (recommended Ra=0.8 µm) steam generator, pressurizer shut off valves, adjustment and regulation in linear movement, and quarter rotation heat exchanger, heater piping connecting flange and boiler devices piping shutters rotating machinery: interior of pumps and compressors device closings with autoclave systems hot air and other gas circuit cryogenic applications Assembly/disassembly: - ORIGRAF gaskets in groove assembly: - During assembly, it is recommended to take precautions to avoid causing any damage to the seal at its introduction into the groove (scratching off the graphite, etc.). - For ORIGRAF type ON 250 seals, be careful with the placement during assembly, the cups must be positioned on the opposite side to the base of the groove. - During disassembly, it is recommended to take precautions so as to remove the seal without altering the depth of the groove (use nonmetallic tools, preferably fiber, and if possible remove the gasket without tools) - ORIGRAF gaskets with limiter: - No particular precautions are required during assembly. It is however necessary to avoid any risk of causing damage to the sealing strip on the flange, such as cuts, scratches, or foreign bodies. CERTIFICATIONS The ORIGRAF seal is PMUC certified by EDF (No. PMUC ) and BAM. The ORIGRAF seal can be made using materials (metal rings) obtained following RCCM. 11

12 CEFIGRAF JDG SEALS CEFIGRAF JDG SEAL CONCEPT The CEFIGRAF JDG seal (cut grooved gasket) is made of a metallic support on which sheets of graphite are inserted into machined grooves. The seal is obtained through the final densification of the graphite when it is tightened in contact with the mechanical stop (also known as metal-metal contact). INSERTION ASSEMBLY ASSEMBLY ON FLAT OR ELEVATED SURFACE The maximum conditions for use depend on a number of parameters, notably the diameter of the seal and the type of assembly (assembly in a groove or between flat surface flanges). CREATION POSSIBILITIES Standard: Stainless steel, other metals upon request. Possibility of standard flange seals (NF EN ASME B16.5) Shapes: circular, rectangular, elliptic, double strip and in bars. Possibility of manufacturing different thicknesses, depending on the thickness of the components. TECHNICAL CHARACTERISTICS MAIN ADVANTAGES OF CEFIGRAF JDG SEAL Advantages of metal-metal contact: it consists of creating a rigid mechanical contact independent of the active part of the graphite gasket which is thus preserved against the general mechanical assembly constraints. The seal's elastic recovery is thus entirely dedicated to the conservation of the seal. This concept also allows the seal to be protected from over-tightening. No creep, as the graphite is assembled in the groove The precise machining of the groove makes it possible to perfectly control the seating pressure on the seal and the densification of the graphite, avoiding all risk of overweighting Monobloc seal, easy to manipulate (no risk of breakage during manipulation) Good sealing due to graphite's expansion Very good endurance in terms of thermal transitions AREA OF USE Max. continuous temp. Min. temp. 500 C/932 F in oxidizing atmosphere * -196 C/ F Max. pressure 20 MPa * Roughness of the sealing area Ra: 1.6 to 12.5 μm (turned surfaces by lath machining) Compression rate: CEFIGRAF seals are designed with a total compression rate of between 40 and 50%, depending on the initial density of the graphite. Seating pressure: numerous characterization tests on the CEFIGRAF JDG seal have made it possible to identify the key parameters linked to the performance of this seal. These make it possible to retain a nominal sitting pressure of 30 and 50 MPa, for the majority of applications. Nominal Sitting pressure PY 0 Sitting pressure MPa APPLICATION AREAS Metal-metal contact Tightening Nuclear: exchangers and openings in manual tools, valves Chemical: exchangers (gaskets with bars), saturated and heated vapor, hydrocarbons Valves: body/bonnet CERTIFICATIONS Option of manufacture with PMUC graphite (EDF certification No ) (* non associated values) 12

13 CEFIGRAF JPR SEALS CEFIGRAF JPR SEAL CONCEPT The CEFIGRAF JPR (flat covered gasket) seal consists of a metal core on which two graphite CEFIGRAF sheets are attached. MAIN ADVANTAGES OF CEFIGRAF JPR SEALS Monobloc seal, easy to manipulate (no risk of breakage during manipulation) Particularly adapted to the creation of complex shaped seals and large dimension seals Good capacity to compensate for surface defects of the contact areas (graphite thickness 1 mm) Good sealing due to graphite's expansion Low creep (low graphite thickness) Possibility of "optimized" seals Adaptation of the graphite strip cross section to the effort available in the nuts and bolts Replacement of existing flat large section seals without modification to the closing or the bolt (dimensions above all identical to the original seal, optimization of the width of the graphite part depending on available effort) AREA OF USE Max. continuous temp. Min. temp. 500 C/932 F in oxidizing atmosphere * -196 C/ F Max. pressure 10 MPa * Roughness of the sealing areas (* non associated values) Ra: 1.6 to 12.5 μm (turned surfaces by lath machining) The maximum conditions for use depend on a number of parameters, notably the diameter of the seal and the type of assembly (assembly in a groove or between flat surface flanges). For use at > 40 bar and for seals of DN > 500, contact us in order to optimize the seal definition. CREATION POSSIBILITIES Possibility of manufacture in different thicknesses Recommendations regarding graphite thickness: - If assembly is between two machined surfaces, graphite thickness of 0.5 mm - If assembly is on a mechanically welded device, graphite thickness of 1 mm Most common designs (additional examples upon request) Thickness Gasket (mm) Thickness Stainless steel (mm) Thickness Graphite (mm) TECHNICAL CHARACTERISTICS Compressibility (ASTM F36) * Elastic recovery (ASTM F36) * (* trial with graphite sheet with 1mm thickness) APPLICATION AREAS 40-50% of the graphite thickness 10-15% of the graphite thickness Internal equipment inspection hatches (complex shaped gaskets) Exchangers (seals with or without bars) Flange seals up to PN40 Large dimension seals for various uses (turbines, etc.) CERTIFICATIONS The CEFIGRAF JPR seal is PMUC certified by EDF (No. PMUC ) 13

14 ORIGRAF SEALS FOR AUTOCLAVE CLOSURE HEADS CONCEPT The principal of this method of closing is to use pressure to push the autoclave plug and to compress the graphite radially in the bore of the valve body. The more the pressure increases, the more the seal is compressed. There are several types of ORIGRAF seals for autoclave closings which can be made up of metal rings (stainless steel, steel, or other upon request) and molded graphite rings (straight or cone-shapes) which ensure radial sealing in the body of the valve as well as on the right of the autoclave plug. MAIN ADVANTAGES No corrosion problems with the STELLITE deposit from the device due to the purity of its PMUC grade graphite (carbon level >99.5%, S and H levels <200ppm) Good sealing due to the graphite's increased density on this type of autoclave assembly Good temperature resistance as the mechanical properties of graphite remain relatively unchanged in high temperatures Good resistance over time due to very low creep Good capacity to compensate for surface defects of the contact areas (barrel and plug) AREA OF USE Max. continuous temp. Min. temp. (* non associated values) CREATION POSSIBILITIES 500 C/932 F in oxidizing atmosphere * -196 C/ F Max. pressure 60 MPa * Roughness of the sealing areas Ra: 1.6 to 12.5 μm (turned surfaces by lath machining) Manufacturing possibilities range from DN 80 to DN 600.

15 LAMINATED SEALS The laminated seal is a sealing solution for valve seat applications in triple offset butterfly valves. CONCEPT AND ADVANTAGES Technetics provides its clients a complete sealing solution, including the laminated seal along with its secondary seal in order to optimize the sealing in line with the valve and to achieve the most restrictive test classes (ANSI Class VI). Overlay of metal and graphite rings unified with a specific adhesive process. Machining of the sealing area according to an elliptical profile. Graphite provides a slight lateral displacement of the rings from one another, enabling them to adjust perfectly to the seat opening. Several graphite densities and thicknesses are available based on the characteristics to be obtained. The purpose of the second seal is to prevent the laminated seal being bypassed by the fluid. The optimal solution consists of combining a laminated seal with a secondary molded ORIGRAF seal with cups (see pg. 7), providing excellent elastic recovery, while preventing any risk of graphite extrusion and underdensification of the material.

Maestral brings together the strengths of Technetics Group, leader in the field of high performance industrial sealing and CEA (French Atomic Energy and Alternative Energy Agency), a major player in research and innovative developments for energy technologies. Maestral's expertise is the result of a successful collaboration, since 1969 between CEA and Technetics Group. Our skill is constantly growing as a result of the real-life cases we study and our experts have the ability to quickly assess situations in order to offer suitable R&D programs and solutions. Maestral technicians are experienced and certified to COFREND (French Confederation for Non-destructive Testing) II, Leak Testing. Maestral has the latest generation of test and characterisation equipment, offering the ability to quickly and thoroughly analyze the behavior of seals. Simulation does not replace tests on mock-ups but it allows the latter as well as experimental artifacts to be reduced. Simulation is an efficient tool for conceiving and optimizing a sealing system by checking its performance in all circumstances, in order to best respond to clients' issues. Calculation for finished elements Today, prediction abilities of models are advanced enough to extrapolate life-size results when the size of the mock-ups or the duration of the tests makes them impossible in real conditions. Our FEA engineers are particularly experienced in the mechanics of largely non-linear behaviors, such as deformations, creep, complex contacts with flanges and friction. Maestral is committed to actively developing numerical simulation tools and resources, applied to sealing. In order to develop product lines or for special applications, Maestral designs and develops specific benches or mock-ups reproducing actual operating conditions. To do so, it calls on the advanced analytical skills of CEA and on the manufacturing and research abilities of Technetics Group. 15
