Definitions

  • the electrical isolation properties of these gaskets are not high enough for a given application or industry. This may be because the material used to provide electrically isolating properties is not a high dielectric material.
  • gaskets with electrically isolating properties are limited to lower temperature applications because they are not capable of withstanding exposure to high temperatures.
  • gaskets with electrical isolating properties use glass reinforced epoxy (GRE).
  • GRE glass reinforced epoxy
  • GRE has a maximum glass transition temperature in the range of from 250 to 350° F. When gaskets with GRE are exposed to temperatures above this range, the GRE becomes soft and rubber-like, and the GRE subsequently lacks the strength to properly support the sealing elements, thus leading to gasket failure.
  • GRE is typically adhered to a core of a gasket through the use of adhesive. This adhesive may fail at elevated temperatures and pressures, which can result in delamination.
  • gaskets incorporating materials having electrically isolating properties have larger thicknesses due to the material that is added to the core of the gasket in order to impart electrically isolating properties.
  • Many common isolation materials have a dielectric strength value of between 400 and 800 volts/mil. Accordingly, a thick gasket is necessary to develop enough voltage resistance for common applications. These higher-thickness gaskets result in limitations on where the gaskets can be used.
  • the gasket includes a core gasket component having a coating or film of dielectric material provided on at least one surface of the core gasket component.
  • the coating or film comprises polyimide, ceramic, or aluminum oxide.
  • the coating or film is formed on all surfaces of the core gasket component, including on the surfaces of any grooves and/or protrusions formed in/on the axial surfaces of the core gasket component. A core gasket component fully encapsulated by the coating or film is also described herein.
  • FIG. 1 is a top plan view of a gasket according to various embodiments described herein.
  • FIG. 2A is a cross-sectional view of the gasket shown in FIG. 1 taken along line 2 - 2 .
  • FIG. 2B is a cross-sectional view of a gasket according to various embodiments described herein.
  • FIG. 2C is a cross-sectional view of a gasket according to various embodiments described herein.
  • the gasket 100 generally includes a core gasket component 110 (also referred to as a retainer) and a dielectric coating 120 formed on at least one surface of the core gasket component 110 (formed on at least the top axial surface of the core gasket component 110 as shown in FIG. 1 ).
  • the core gasket component 110 may include one or more grooves formed in the axial surfaces of the core gasket component 110 , with each groove having a sealing element 130 , 140 disposed therein.
  • the core gasket component 110 can generally have a disc shape such that the gasket 100 is suitable for placement between, e.g., flanges of adjacent pipe segments.
  • the dimensions of the core gasket component 110 are generally not limited and may be selected based on the specific application in which the gasket is to be used.
  • the material of the core gasket component 110 is generally not limited provided the core gasket component 110 is suitable for use in a gasket, including meeting or exceeding the properties required for the specific application in which the gasket 100 is used.
  • the material of the core gasket component 110 will typically be an electrically conductive material since an object of the present application is to provide an electrically isolating coating to the core.
  • the material of the core gasket component 110 is a metal.
  • the material of the core gasket component 110 is stainless steel.
  • the core gasket component 110 may include one or more grooves formed in one or more axial surface of the core gasket component 110 .
  • the grooves are circular grooves aligned concentrically with the core gasket component 110 , though other configurations can be used.
  • the grooves formed in one axial surface are identical to the grooves formed in the opposing axial surface, though other, non-symmetric configurations are also possible.
  • the core gasket component 110 includes two concentrically aligned grooves formed in at least a top axial surface of the core gasket component 110 , with each groove having a sealing element 130 , 140 disposed therein.
  • the core gasket component 110 may include raised features in place of or in addition to grooves. Raised features can be used to, for example, lock a seal in place or serves as stress concentrators.
  • FIGS. 2A-2C a cross-sectional view of the gasket 100 of FIG. 1 taken along line 2 - 2 is shown, with each of FIGS. 2A, 2B, and 2C showing a different embodiment of the gasket 100 .
  • the dielectric coating 120 is formed on at least one surface of the core gasket component 110 ; in FIG. 2B , the dielectric coating 120 is formed on at least one surface of the grooves 115 formed in the core gasket component 110 ; and in FIG. 2C , the dielectric coating 120 is formed on all surfaces of the core gasket component 110 , including the surfaces of the grooves 115 .
  • the core gasket component 110 may also include one or more features that protrude away from the axial surfaces 111 of the core gasket component 110 .
  • the dielectric coating 120 may be disposed on one or more surfaces of the raised features.
  • each groove 115 is not limited.
  • the cross-sectional shape, depth, width, and placement (e.g., radial distance away from the inner diameter) of each groove is generally not limited.
  • two grooves 115 are included in each axial surface 111
  • the grooves 115 have a generally square cross-sectional shape
  • the grooves 115 are located in close proximity to the inner diameter of the core gasket component 110
  • the grooves 115 formed in one axial surface are identical in shape, depth, and location to the grooves 115 formed in the opposing axial surface.
  • the grooves 115 formed in the core gasket component 110 are used as sealing grooves. These sealing grooves are configured such that one or more sealing elements can be disposed within the sealing grooves 115 . Any type of sealing element can be disposed in the sealing grooves 115 , including for example E-rings, C-rings, O-rings, and spiral wound-type seals. In some embodiments, and as shown in FIGS. 2A-2C , an E-ring 130 can be disposed in the radially outer groove 115 and a lip seal 140 can be disposed in the radially inner groove 115 .
  • the grooves 115 are shaped and dimensioned such that only a single sealing element fits within the groove.
  • the radially outer groove 115 can be shaped and dimensioned such that an E-ring disposed therein occupies the entirety of the groove 115 and leaves no additional space for other components, such as a compression limiter.
  • the groove 115 can be shaped and dimensioned in this manner because in the embodiments described herein, the gasket retainer (i.e., core gasket component 110 ) itself may act as the compression limiter, thereby eliminating the need for a separate compression limiter component being incorporated into the gasket 100 .
  • the gasket 100 further includes a dielectric coating 120 .
  • the dielectric coating 120 is applied to at least one surface of the core gasket component 110 , either partially (such as is shown in FIGS. 2A and 2B ) or completely covering the surface (such as is shown in FIG. 2C ) to which it is applied.
  • the dielectric coating 120 is applied completely to every surface of the core gasket component 110 , including the surfaces of any grooves 115 (and/or raised features) formed in/on the core gasket component 110 .
  • the dielectric coating 120 can be formed on the core gasket component 110 so as to fully envelope the core gasket component 110 . In this manner, this dielectric coating 120 can electrically isolate the metallic core gasket component 110 and increase the range of applications in which the gasket 100 can be used.
  • the dielectric coating 120 formed on the one or more surfaces of the core gasket component 110 is formed with a uniform thickness, including when the dielectric coating 120 is provided on all surfaces of the core gasket component 110 .
  • the thickness of the dielectric coating is generally not limited. In some embodiments, the thickness of the dielectric coating is in the range of less than 6 mm. In some embodiments, the thickness of the coating is 0.381 mm or less, such as 0.127 mm or less.
  • the thickness of the dielectric coating 120 may vary, such as in a scenario where the thickness of the coating on the groove surfaces (or on raised feature surfaces) is less than the thickness of the coating on other surfaces (axial or radial) of the core gasket component 110 .
  • the thickness of dielectric coating on groove and/or raised feature surfaces can be greater than on the other surfaces of the core gasket component 110 .
  • the thickness of the dielectric coating can also vary from groove to groove.
  • the dielectric coating 120 is polyimide, polyamide, ceramic, or aluminum oxide, with polyimide being a preferred material.
  • the gasket 100 is free of glass reinforced epoxy (GRE).
  • GRE glass reinforced epoxy
  • the coating 120 may be applied to the core gasket component 110 using any known technique for applying a coating to a base substrate.
  • the coating 120 is applied to the core gasket component 110 in a liquid form and then cured to form a solidified coating.
  • the curing is carried out in a continuous manner, which improves the throughput of the manufacturing process and makes the process more economically feasible.
  • the continuous curing process is carried out using a continuous infrared process or by continuously passing the core gasket component having liquid coating disposed therein through a convection oven.
  • the coating 120 is applied directly to the core gasket component 110 without the need for an intermediate adhesive or bonding layer.
  • the dielectric coating 120 being applied to all surfaces of the core gasket component 110 provides a gasket 100 that is electrically isolated from both any seals used with the gasket as well as from metallic flange surfaces that the gasket may be disposed between.
  • the gasket described herein may further include an inner diameter seal, such as the inner diameter seal described in U.S. Published Application No. 2015/0276105. Other inner diameter seals may also be used.
  • the gasket described herein may be thinner, seal better, improve electrical isolation, and/or provide a more robust and reliable platform for fire-safe gaskets than previously known gasket materials.
  • the gasket material described herein also advantageously eliminates any need for glass reinforced epoxy (GRE) in the gasket material.
  • GRE glass reinforced epoxy
  • the gasket material described herein also provides stabilized material thickness and tolerance controls.
  • the gasket material described herein expands the operating temperatures and electrical resistance of the product and allows for entry into new spaces of development, such as steam and nuclear service.
  • the gasket described herein also expands pressure capabilities.
  • the gasket described herein further provides high dielectric strength, permeation resistance, tight tolerance capabilities, impact resistance, strong environmental protection, improved chemical resistance, and a simplified structure (i.e., less components to the overall gasket).
  • problems that may be solved and/or advantages that may be achieved by the gasket described herein include, but are not limited to: improving electrical isolation properties of the dielectric components of the gasket through the use of high dielectric material; reducing external corrosion through complete encapsulation of the gasket retainer; increasing temperature ranges, allowing for use in wider variety of applications where current offerings of isolating gaskets include GRE; eliminating observed problem of failure of adhesive between GRE and retainer material commonly seen at elevated temperatures and pressures; decreasing gasket thickness and thereby allowing for use in a wider variety of applications through the use of thinner dielectric materials, which allows for ease in installation; decreasing the number of gasket components and thereby reducing complexity by eliminating, e.g., a backup ring compression limiting device as what is currently seen in similar isolating gasket configuration; increasing dimensional stability through use of materials that have controlled tolerances; increasing the ability to hold tight tolerances throughout the manufacturing process; improving sealing performance through the elimination of permeation in current gasket facing material as well as providing a more dimensionally stable gas
