  9. Flange Face Surface Finish - sunnysteel, finished machining smoothness flanges

    The flange face has small grooves as you can see in the image. This machining is known as a serration. Flange face can be smooth or serrated type. Which type of face to use is depends on the type of the gasket and service of the fluid. Smooth finish is used with metallic gasket whereas serrated finish is used with non-metallic gasket.

  10. Flange Face Surface Finish | Sunny Steel Enterprise Ltd.

    The most widely used of any flange surface finish, because practically, is suitable for all ordinary service conditions. Under compression, the soft face from a gasket will embed into this finish, which helps create a seal, and a high level of friction is generated between the mating surfaces.

    The flange facings are machine finished to ANSI/ASME B16.5 requirements. Ring Type Joint (RTJ) (Class 300 and larger) - This flange is normally used for high pressure gas pipe work. Ring type gaskets must be used on this type of flange.

  12. Flange Finishes | Gasket Resources Inc

    We recommend that metal flange faces be machined with a concentric-serrated finish of 125-500 AARH, with 250 AARH being the optimum for non-metallic gaskets. Phonographic serrations can also be used with our materials. It should be recognized, however, that their continuous leak path makes them more difficult to seal.

  13. Flanges - Flange Face Finish - Piping

    Machining of gasket faces of flanges to a smooth finish of Ra = 3.2 - 6.3 micrometer (= 125 - 250 microinches AARH) AARH stands for Arithmetic Average Roughness Height. It is used to measure the roughness (rather smoothness) of surfaces. 125 AARH means 125 micro inches will be the average height of the ups and downs of the surface.

  16. Manage & Understand Flange Face Damage

    The flatness of the flange also affects a gaskets ability to seal. A lack of flange flatness can also be considered damage. This can occur because of excessive loads on the flange or as the result of errant machining of the flange surface. Soft gaskets will also tend to conform to and seal areas of poor flatness better than a hard gasket.

  19. RF, FF, RTJ Flange Face and Finish - Projectmaterials

    According to the ASME/ANSI specifications, the serrated, spiral serrated, and concentric flange face finish should have an average roughness of 125 inch to 250 inch (3.2 m to 6.3 m). The tool used to imprint a rough finish on the flange should have a radius of 0.06 inch (1.5mm) or larger.

  20. Rotor Replacement Myths | Know Your Parts

    Flange runout can be corrected with tapered shims that are available to correct a runout of 0.003 inch (0.075 mm) to 0.009 inch (0.230 mm). A runout of more than 0.005 inch (0.125 mm) at the bearing flange cannot be corrected by the use of a shim. The combination of rotor and bearing flange could prevent the rotor from being turned.

  21. Serrated vs non serrated flange face finish - Valve , finished machining smoothness flanges

    Serrated is not smooth, non-serrated is smooth. Ductile Iron means the surface is "rough", but not machined. Spiral and x per inch is a machined finish to create a roughened surface to "grip" the gasket and in theory provide more obstructions to gas or liquid flow.

  29. What is the Impact of Flange Finish on Gasket Performance?

    Metallic flange surfaces can range from a rough casting to the smoothness produced by lapping. A critical and fundamental aspect of sealing is the level of friction between the flange and gasket surfaces. The roughness of the flange faces can have a dramatic effect on gasket creep relaxation, blow out resistance and bolted joint tightness.
