A filter element with an improved mounting frame and method of assembly are provided. The filter element includes a filter media pack with a mounting frame attached to the outer periphery of the filter media pack. The mounting frame defines a channel that holds a shut-off material for preventing leakage of an adhesive securing the mounting frame to the filter media pack. A filter element that includes a polymeric material between the filter media pack and the adhesive is also provided. The shut-off material may be pre-formed or applied in a flowable state.

A method of manufacturing an annular seal (500), the method comprising the steps of: (i) providing an intermediate (10) having an annular layer of an elastomeric first material (100) bonded to an annular layer of a second material (200), the second material being different from the first material; and (ii) machining the intermediate to form the annular seal comprising the first and second materials, wherein: • the intermediate (10) is machined to provide a profile that is generally U-shaped and is defined by a radially extending wall (1), an outer flange wall (2) extending axially from the radial wall (1), and an inner flange wall (3) facing the outer flange wall (2) and extending axially from the radial wall (1); and • the annular seal (500) has a seal lip (4) that extends radially inward from the inner flange wall (3), whereby the seal lip (4) is formed from the second material (200) and the second material has one or more of: a lower coefficient of friction, a higher heat resistance, a higher wear resistance and/or a higher chemical resistance than the first material (100).

A non-conductive multi-layered ringed sealing gasket for mating pipe joints along a piping assembly comprising at least two mutually joined ring-shaped bodies each having a top surface portion, a top gasket section bonded with, adhered to, or part of the top surface portion, a bottom surface portion, and a bottom gasket section bonded with, adhered to, or part of the bottom surface portion. The bottom surface portion of one of the bodies is mated to a top surface portion of another of the bodies forming multi-layers. The at least two mutually joined ringed-shaped bodies in combination comprise a sealing ring so that the top and bottom gasket sections are dimensioned with a total thickness no greater than the diameter of the piping assembly in each pipe-joint half mated by the gasket. The ringed sealing gasket can be comprised of a metal and the bottom gasket section is separated from the top gasket section by an inner portion that is comprised of one or more non-conductive materials that are ductile but do not flow during dynamic motion and forces associated with the motion of the pipe joints wherein at least one layer of the inner portion includes rings with toroidal wrapped fibers having voids filled with adhesives such that shear forces occurring during movement of the piping assembly are distributed predominantly in the tensile direction along the axial length of the fibers, thereby eliminating cracking of the gasket under excessive loads.
摘要:
Verfahren zum Herstellen eines Funktionselements insbesondere für Flachdichtungen, bei welchen eine Funktionsmateriallage mit einem Siebbereich (14) versehen wird, in welchem zwischen Fäden (34, 38) eines Gewebes oder Geflechts (30) Durchlassöffnungen (44) zum Durchströmen für ein Fluid freiliegend sind, derart zu verbessern, dass eine möglichst gute Abdichtung um die Siebbereiche (14) herum möglich ist, wird vorgeschlagen, dass die Funktionsmateriallage mit einem querschnittsdicht ausgebildeten Abdichtbereich (18) versehen wird, in welchem die Durchlassöffnungen (44) des Gewebes oder Geflechts (30) durch Erweichen und Verpressen eines die Durchlassöffnungen (44) füllenden Füllmaterials (52) verschlossen werden.
摘要:
A seal ring includes a weld and a thermoplastic material. The thermoplastic material has a weld elongation-at-break of at least 3%. The thermoplastic material can have a glass transition temperature of at least 100oC. The thermoplastic material with the weld can have a weld elongation-at-break of at least 3%. The seal ring can have a circumference of at least 0.62 meters. The seal ring can have a coefficient of friction of not greater than 0.45.
摘要:
A combination seal comprising two chemical seals (4a, 4b), each between a first surface of a sealant (2a) and a surface of a substrate (2b) and a physical seal (5) between a second surface of first chemical seal and a second surface of a second chemical seal. The chemical seals are formed by applying the sealant to two substrates and curing the sealant. The physical seal is formed by clamping the chemical seals together. The resulting combination seal has good corrosion resistance of a chemical seal and is re-sealable allowing easy re-work. A method for forming the combination seal.
