SPIRAL WOUND GASKET
DETAILED DESCRIPTION:
Product Type:XINSEN-SD
Outstanding Features:
This exceptional spiral wound gasket is meticulously designed with solid outer and inner rings. Ingeniously, an inner ring has been incorporated to significantly enhance the gasket's performance. This innovation ensures precise centering on the flange face through an external guide ring. The inner ring's addition is a strategic move to avert potential implosion into the pipe during installation, shield the sealing element from extreme temperatures and diverse mediums, and fill any voids between flanges to thwart erosion, thus minimizing failure risks. Typically crafted from the same alloy as the winding, the inner ring is a hallmark of the DIN 2699 standard (German), which mandates inner rings in all spiral wound gaskets. For gaskets with PTFE filler, ASME B16.20 standards dictate the necessity of inner rings, which are also deemed crucial for those with graphite fillers. This sophisticated profile seamlessly integrates with both raised and flat-faced flanges. Furthermore, the external ring fortifies the gasket with additional radial strength, preventing blowouts and doubling as a compression stop. While often constructed from carbon steel with protective painting or zinc plating to combat corrosion, the outer ring can also be fashioned from high-performance alloys for applications requiring resistance to elevated temperatures and more severe mediums.
