Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

The Flexitallic Gasket with 321 Inner Ring and High-Quality Winding Material is engineered for optimal performance, featuring a robust solid outer and inner ring construction. The innovative design includes an added inner ring, enhancing performance and ensuring precise alignment on the flange face. This inner ring, crafted from the same alloy as the winding, prevents implosion during installation, safeguards the sealing element from harsh temperatures and mediums, and fills voids between flanges to halt erosion. It is a critical component, particularly in designs with PTFE filler per ASME B16.20 standards, and considered essential with graphite fillers. Adhering to the DIN 2699 specifications, this gasket profile is recommended for both raised and flat-faced flanges. The external guide ring not only provides additional radial strength to avert blowouts but also serves as a compression limiter, making it an indispensable element in high-temperature and severe medium applications. Typically, the outer ring is made of corrosion-resistant carbon steel, though it can be crafted from superior alloys to meet the demands of extreme environments.
