In a flame arrester arrangement which is formed from two metal strips (8, 9) which are wound together to form a disk having an approximately circular outer circumference and of which a first metal strip (8) is a smooth strip and the second metal strip (9) is a fluted strip having defined fluting, the two strips (8, 9), by bearing against one another, forming defined gaps (11) for passage of a fluid and being held in position relative to one another by fixing pins inserted into radial bores (6), the radial bores (6) can be incorporated without deforming the gaps (11) even in the region of the bores (6) by virtue of the fact that the bores (6) are incorporated by spark erosion without deforming the fluting formed in the second metal strip, such that the gaps (11) are also present in the region of the bores (6) in the manner defined by the fluting.
A method of incorporating radially oriented bores (6) for fixing pins in a flame arrester arrangement (1) which is formed from two metal strips (8, 9) which are wound together to form a disk having an approximately circular outer circumference and of which a first metal strip (8) is a smooth strip and the second metal strip (9) is a fluted strip having defined fluting, the two strips (8, 9), by bearing against one another, forming defined gaps (11) for passage of a fluid, wherein the wound flame arrester arrangement (1) is completely closed off axially on both sides by retaining plates (5), and wherein the bore is incorporated radially inward from the outer circumference by a spark erosion electrode (7) while injecting a cooling liquid (10).
A flame arrester arrangement which is formed from two metal strips (8, 9) which are wound together to form a disk having an approximately circular outer circumference and of which a first metal strip (8) is a smooth strip and the second metal strip (9) is a fluted strip having defined fluting, the two strips (8, 9), by bearing against one another, forming defined gaps (11) for passage of a fluid and being held in position relative to one another by fixing pins inserted into radial bores (6), wherein the bores (6) are incorporated by spark erosion without deforming the fluting formed in the second metal strip, such that the gaps (11) are also present in the region of the bores (6) in the manner defined by the fluting.
