Ordering FLEXITALLIC Gaskets for Special Flange Designs In order for FLEXITALLIC to design a gasket suitable for the application, it is imperative that complete details be submitted for review. The information we require is the following: 1. Type of flange facing 2. Dimensions of the gasket seating surfaces 3. Number, size and material of bolts 4. Bolt circle diameter 5. Operating pressure & temperature (process media if known) 6. Hydrostatic test pressure 7. Initial bolt pre-stress 8. Customer preference on gasket materials FLEXITALLIC supplies engineering data sheets at no cost on which this information may be submitted. As a gasket manufacturer, it is impossible for us to review every flange design to make certain that flange rotation and flange stresses are within allowable limits defined in the Code. We proceed on the assumption the design engineer has followed the design criteria established by the ASME Boiler Code and that the flanges are sufficiently rigid under the most severe condition to preclude the possibility the gasket could become unloaded either during operating conditions or hydrostatic test conditions. We are aware that most flange designers do not take into consideration flange rotation at test conditions prior to finalizing their design. We also, of a practical necessity, must assume the bolt material being used is adequate for all conditions including operating pressure at operating temperature and hydrostatic test pressure at ambient temperature. The use of the optimum material for bolts is a very complex subject and we suggest reviewing currently available technical literature for guidance in the proper selection of bolting material for piping and pressure vessel applications.

Ordering FLEXITALLIC Gaskets for Special Flange Designs Overall Dimensional Limits In general, the only limits on the dimensions of heat exchanger gaskets are the limits of sizes of material available. Note: In addition to the above information, drawings of your application are always helpful for proper dimensioning of gaskets. Dimensions • Outside Diameter • Inside Diameter • Shape • Style Number • Thickness • Material (metal or metal and filler) • Rib width • Distance from centerline of gasket to centerline of ribs • Radii • Specify number, placement, bolt circle radius and size of bolt holes 7 8 8 Qty. Holes 6 3 4 6 2 1 4 6 6 Legend: 1. O.D. gasket 5. Bolt circle radius 2. I.D. gasket 6. C of gasket to C of rib 3. Width of rib 7. Radius around bolt 4. Radius on rib 8.
