Spiral Wound Gasket is the ideal gasket for it's flexibility, resilence, and multi-use applications. A narrow strip of a metal hoop is spirally wound under tension with a filler cushion between the laminations of the metal and is spot-welded at both ends.
The first step in spirally wound gasket construction is to determine which type of gasket will be best suited for your projects needs. There are four basic types of Spiral Wound Gasket: the gasket for notched joint flange; a gasket with an inner ring for a raised face flange; a gasket with an outer ring for smoothing flat welded flange and ; a gasket with an inner and outer rings for smoothing butt welded gaskets.
Questions to ask yourself will be what are the compression specifications, heat specifications, pressure exerted, is it a raised or flat flange, and so on. Knowing all the details of your project will help you to determine which sealer will be most suited to your Spiral Wound Gasket.
