Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Experience unparalleled sealing excellence with our spiral wound gasket, meticulously crafted with a robust solid outer and inner ring. For superior performance, an inner ring has been expertly integrated, ensuring the gasket is impeccably centered on the flange face by means of an external guide ring. This crucial inner ring is designed to prevent the gasket from imploding into the pipe during installation, shielding the sealing element from harsh temperatures and aggressive mediums, filling voids between flanges to halt erosion, and significantly reducing failure risks. Typically, the inner ring is composed of the same high-grade alloy as the winding. Compliant with the DIN 2699 German standard, inner rings are a mandatory feature in all spiral wound gaskets. According to ASME B16.20 standards, inner rings are essential for gaskets utilizing PTFE filler and are strongly recommended for those with graphite fillers. This advanced profile is ideally suited for raised and flat-faced flanges. The external ring not only reinforces radial strength to prevent blowout but also acts as a vital compression stop. Often constructed from carbon steel, which is painted or zinc plated for corrosion resistance, it can also be crafted from specialized alloys to withstand higher temperatures and more severe conditions.
