えられる。However, although this spiral-wound gasket can be used for ordinary steel flanges, it damages the flange surface of expanded aluminum flanges because the hoop of this gasket made of thin stainless steel plates is harder than that of aluminum flanges. To compensate for this deficiency, it is conceivable to use a thin aluminum plate for the hoop of the spiral gasket.

製フランジ用うず巻形ガスケットの製造方法である。Structure of the Invention Next, the present invention involves a process of overlapping a hoop 1 made of a thin aluminum plate with a corrugated cross section and a filler 2 made of asbestos paper or the like and winding it in a spiral shape to form an annular gasket body ae, and a process at the beginning and end of the winding. In the hoop 1 of thin aluminum plate,
Stainless steel tape 3 thinner than the thickness of the gasket body
a step of overlapping a portion of the stainless steel hoop 3 and connecting the parts by cross-welding, or a step of inserting the stainless steel hoop 3 between the hoops 1 without spot welding; This is a method for manufacturing a spiral-wound gasket for an aluminum flange, which includes a step of spot welding after winding the gasket one turn or more.
以下本発明の構成を図面を用いて説明する。The configuration of the present invention will be explained below with reference to the drawings.

断面形状はく状にすることが好ましい。First, filler 2 is superimposed on this hoop l and wound in a spiral shape to form an annular gasket body a. Next, insert gas into the beginning and end of the winding of the gasket body a.
) A stainless steel tape 3 thinner than the thickness of the main body a is wound at least one turn, preferably one to three turns, to form a convex shape. Note that it is preferable that the stainless steel tape 3 has a foil-shaped cross section.

The hoop 1 and the stainless steel tape 3 are connected by partially overlapping the finished aluminum thin 7-pipe IK stainless steel tape 3 and spot welding the overlapping portion, and then forming the trench stainless steel tape 3vil. : After wrapping the stainless steel tape 3 at least once, spot weld the overlapping or mating parts of the stainless steel tapes 3. After wrapping the stainless steel hoop at least once, spot weld the overlapped parts of the stainless steel tapes 3 together. Spot welding may also be used.

Further, in this case, the metal ff1ffi may be fitted to the inner periphery of the inner protruding strip, or to the inner and outer protruding strips, respectively. By attaching this metal ring, the tightening pressure against the gasket body a can be increased and the gasket can be used for high-pressure fluid.

なことはなく高締付圧力に耐えうろことができる。Effects of the Invention ■ The present invention can be achieved by overlapping a portion of stainless steel tape over the hoops of thin aluminum plates at the beginning and end of the winding of the gasket body a, and connecting the parts by spot welding;
Alternatively, the stainless steel tape is completely inserted between the hoops of the thin aluminum plate, the stainless steel tape is then wrapped, and the stainless steel tapes are firmly welded together, so the gasket body a is t'! ! It can withstand high tightening pressure without coming loose.
