Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This spiral wound gasket is ingeniously crafted with a robust outer and inner ring, ensuring unparalleled durability and efficiency. Notably, an advanced inner ring has been expertly incorporated to significantly boost gasket performance. This inner ring plays a pivotal role in preventing potential issues such as implosion into the pipe during installation. It also provides essential protection for the sealing element against extreme temperatures and various mediums. Additionally, it adeptly fills the void between flanges, safeguarding against flange erosion and significantly reducing the risk of failure. The inner ring is meticulously crafted to match the alloy of the winding, adhering to the prestigious DIN 2699 standard (German), which mandates inner rings in all spiral wound gaskets. According to ASME B16.20 standards, inner rings are indispensable in gaskets with PTFE filler and are highly recommended for those with graphite fillers. This superior gasket profile is versatile, perfectly suited for both raised and flat-faced flanges. Enhancing its reliability even further, the external ring imparts additional radial strength, effectively preventing blowout and serving as a vital compression stop. The outer ring, commonly made of carbon steel—either painted or zinc plated to combat corrosion—can also be crafted from specialized alloys to withstand higher temperatures and more severe medium applications.
