Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing our Flexitallic Spiral Gasket with SS316 Winding and Graphite Filler. Engineered with precision, this exceptional spiral wound gasket boasts an integral solid outer ring and an inner ring for superior performance. The inclusion of an inner ring dramatically enhances gasket reliability by preventing collapse during installation, safeguarding the sealing element against extreme temperatures and aggressive mediums, and eliminating voids between flanges to minimize flange erosion. Crafted from the same alloy as the winding, the inner ring is essential for gaskets with PTFE filler as per ASME B16.20 standards and is crucial for those with graphite fillers, as outlined by the DIN 2699 German standard. Particularly effective for both raised and flat flange faces, the external guide ring ensures perfect gasket alignment and imparts additional radial strength to avert blowouts, while also serving as a compression limiter. Typically fashioned from corrosion-resistant carbon steel—either painted or zinc plated—the outer ring is also available in alloy variants to withstand higher temperatures and more demanding applications. Experience the pinnacle of sealing technology with a product that's as robust as it is reliable.
