Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This remarkable spiral wound gasket is expertly engineered with a robust outer and inner ring design. For superior performance enhancement, an additional inner ring has been strategically inserted. This ensures precise centering of the gasket on the flange face with the aid of an external guide ring. The inner ring's inclusion is pivotal; it safeguards against potential implosion into the pipe during installation, shields the sealing element from harsh temperatures and media, fills the void between flanges to protect against erosion, and significantly reduces failure risks. Crafted usually from the same alloy as the winding, the inner ring's importance is underscored by its specification in all spiral wound gaskets per the DIN 2699 standard (German). For gaskets with PTFE fillers, inner rings are mandated by ASME B16.20 standards and are deemed crucial for those with graphite fillers. This profile is ideally suited for use in raised and flat faced flanges. The external ring contributes vital radial strength to avert gasket blowout and serves as a compression stop. Also commonly utilized in raised and flat faced flanges, the outer ring is typically made from carbon steel, either painted or zinc-plated for corrosion resistance, but can be crafted from alloys for higher temperature and demanding applications.
