Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This exceptional ASME B16.20 Spiral Wound Gasket, enhanced with a 304 Inner Ring and enriched by Graphite Filler, features an expertly engineered solid outer and inner ring. The inner ring is meticulously incorporated to optimize gasket performance, while the precision-engineered external guide ring ensures seamless and accurate centering of the gasket on the flange face. The inclusion of the inner ring is crucial, as it safeguards against the gasket's implosion into the pipeline during the installation process, shields the sealing element from extreme temperatures and aggressive mediums, fills the void between flanges to avert erosion, and significantly reduces the risk of potential failures. Manufactured to align with the DIN 2699 German standard, which mandates inner rings, this meticulously designed gasket is compatible with PTFE filler and is highly recommended for use with graphite fillers according to ASME B16.20 standards. Perfectly suitable for raised and flat-faced flanges, the external ring endows additional radial strength to guard against gasket blowout and also functions as a reliable compression stop. Typically crafted from carbon steel, which is either painted or zinc-plated to resist corrosion, the outer ring can also be constructed from specialized alloys to accommodate higher temperatures and more challenging applications.
