Product Description

Product Description

SPIRAL WOUND GASKET

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing our innovative spiral wound gasket, a marvel of engineering designed with solid outer and inner rings. Enhancing its performance, an inner ring is strategically added, offering superior protection against extreme temperatures and corrosive mediums. This inner ring also fills the flange void, preventing erosion and minimizing any risk of structural failure. Typically crafted from the same alloy as the winding, the inner ring is essential for gaskets utilizing PTFE filler under ASME B16.20 standards and is crucial for gaskets with graphite fillers. According to the DIN 2699 standard, inner rings are mandatory for all spiral wound gaskets, ensuring unparalleled reliability. Ideal for both raised and flat faced flanges, the external guide ring ensures precise centering on the flange face and provides additional radial strength to withstand high pressures, acting as a robust compression stop. While often made from corrosion-resistant carbon steel, outer rings can be constructed from specialized alloys to endure higher temperatures and more severe conditions.
