Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

The Spiral Wound Gasket, a masterpiece of engineering, features a robust solid outer and inner ring. This design includes an ingeniously inserted inner ring, which significantly enhances the gasket's overall performance. The external guide ring ensures precise centering on the flange face, providing unmatched stability. The inner ring plays a pivotal role by preventing any potential implosion of the gasket into the pipe during installation. It acts as a safeguard for the sealing element against extreme temperatures and aggressive mediums, fills voids between flanges to avert flange erosion, and dramatically reduces failure risks. Crafted usually from the same alloy as the winding, the inner ring adheres to the stringent DIN 2699 standards, which specify its use in all spiral wound gaskets. As per ASME B16.20 standards, inner rings are essential for gaskets with PTFE filler and are highly recommended for those with graphite fillers. This profile is predominantly utilized in raised and flat-faced flanges. Moreover, the external ring furnishes additional radial strength, significantly mitigating the risk of gasket blowout and acting as an effective compression stop. Often composed of carbon steel, which may be painted or zinc-plated to combat corrosion, it can also be manufactured from alloys for enduring higher temperatures and more challenging medium applications.
