Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This premium spiral wound gasket boasts a robust construction with both solid outer and inner rings, elevating its performance to exceptional levels. The inner ring is seamlessly integrated to prevent gasket implosion into the pipe during installation, offering unmatched protection to the sealing element against extreme temperatures and harsh mediums. It fills the void between flanges, safeguarding them from erosion and minimizing the risk of failure. Typically crafted from the same high-quality alloy as the winding, the inner ring's importance is underscored by standards like DIN 2699 (German), which mandate its inclusion in all spiral wound gaskets, and ASME B16.20, which requires it for PTFE fillers and highlights its significance for graphite fillers. This well-engineered profile is ideal for use in both raised and flat-faced flanges, with the external guide ring ensuring precise gasket centering on the flange face. This outer ring, which also serves as an effective compression stop, grants additional radial strength to thwart gasket blowout. Crafted from corrosion-resistant carbon steel, it can also be manufactured using alloys for applications requiring higher temperatures and exposure to severe mediums.
