Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This spiral wound gasket is engineered with solid outer and inner rings, ensuring exceptional performance. An enhanced inner ring is meticulously inserted to boost gasket functionality while the external guide ring ensures precise centering on the flange face. This thoughtfully incorporated inner ring prevents the gasket from imploding into the pipe upon installation, offers robust protection to the sealing element against extreme temperatures and harsh mediums, fills flange voids to avert erosion, and significantly minimizes failure risks. Typically crafted from the same high-quality alloy as the winding, the inner ring complies with the German DIN 2699 standard, which mandates inner rings in all spiral wound gaskets. According to ASME B16.20 standards, inner rings are essential for gaskets with PTFE filler and are highly recommended for those with graphite fillers. This design is optimally suited for raised and flat-faced flanges. The external ring not only imparts additional radial strength to prevent gasket blowout but also acts as a reliable compression stop. Typically, the outer ring is crafted from carbon steel, either painted or zinc-plated to resist corrosion, but can be made from specialized alloys for applications involving higher temperatures and more aggressive mediums.
