A metallic or semi-metallic gasket system. High sealing pressure at the metal corrugation High blow out resistance In case of metal to metal, a perfect flange surface (ra < 3,2) is required

Pioneer brand metal jacketed gaskets are normally supplied with high temperature asbestos filler. The standard filler is normally sufficient for applications up to 900° F. Other soft fillers are available for higher temperatures or special applications including graphite. Standard metals used to make jacketed gaskets, regardless of the type are: Copper, Stainless steel types - 304, 316 & 321, Brass, Aluminum, Soft steel & Nickel.-Double Jacketed Gasket - Double - jacketed gaskets are probably the most commonly used style of gasket in heat exchanger / applications. Since most double-jacketed gaskets are custom made, there is virtually no limit to the size, shape or configuration in which these gaskets can be made. It must be remembered that the primary seal against leakage, using a double-jacketed gasket is the metal inner lap where the gasket is thickest before being compressed and densest when compressed. This particular section flows effecting the seal. As a consequence the entire inner lap must be under compression, providing a secondary seal. -Single - Jacketed Gasket - Single-jacketed gaskets are normally used for relatively narrow applications similar to the French type. They are made by encasing a soft filler on one face, both edges and a portion of the other face with a metal. -Single - Jacketed Overlap Gasket - In the single-jacketed overlap construction the maximum flange width is approximately 1/4". This type of gasket is used when total enclosure of the soft filler material is required and then the flange width makes it impractical double-jacketed gasket.
