Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Envision a spiral wound gasket that truly stands out with its robust construction, featuring both a solid outer and inner ring. The inner ring is ingeniously designed to boost the gasket’s performance, providing a reliable external guide to perfectly center the gasket on the flange face. This enhancement not only shields against potential implosion into the pipe during installation but also offers protection from extreme temperatures and mediums. Furthermore, it adeptly fills voids between flanges to prevent erosion and minimizes the likelihood of failure. Crafted typically from the same alloy as the winding, the inner ring adheres to the stringent DIN 2699 German standards, requiring its inclusion in all spiral wound gaskets. This is crucial for gaskets with PTFE filler, as per ASME B16.20 standards, and is highly recommended for those with graphite fillers. Designed for use in both raised and flat-faced flanges, the external ring serves as a powerful force, adding radial strength to thwart gasket blowout while acting as a stop for compression. Often forged from carbon steel (painted or zinc plated for corrosion resistance), the outer ring can also be crafted from alloys for high-temperature and severe medium applications, ensuring optimal durability and performance.
