Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This top-tier spiral wound gasket is crafted with a solid outer and inner ring, skillfully engineered for superior performance. An inner ring is meticulously inserted to elevate the gasket's functionality, ensuring precise alignment on the flange face through an expertly designed external guide ring. This essential inner ring plays a vital role in preventing any implosion of the gasket into the pipe during installation. It acts as a robust shield, safeguarding the sealing element from extreme temperatures and aggressive mediums, while seamlessly filling the void between flanges to avert flange erosion, effectively minimizing the risk of failure. Typically, the inner ring is composed of the same high-quality alloy as the winding. According to the DIN 2699 standard (German), inner rings are mandatory for all spiral wound gaskets. Compliance with ASME B16.20 standards dictates the necessity of inner rings for gaskets featuring PTFE filler, and they are highly recommended for those with graphite fillers. This gasket profile is perfectly suited for both raised and flat-faced flanges. The external ring offers additional radial strength, preventing any risk of gasket blowout and also serves as a compression stop. This profile is ideal for raised and flat-faced flanges. The outer ring, often crafted from durable carbon steel (painted or zinc-plated to resist corrosion), can also be manufactured from specialized alloys for applications involving higher temperatures and more challenging mediums.
