Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This advanced spiral wound gasket, crafted from premium materials, features a robust outer ring and a strategically incorporated inner ring to significantly enhance its performance. The meticulously engineered external guide ring ensures precise centering of the gasket on the flange face. The innovative inner ring is crucial, preventing any implosion of the gasket into the pipe during installation, safeguarding the sealing element from extreme conditions, and filling voids to avert flange erosion, thereby minimizing the risk of failure. Typically composed of the same high-quality alloy as the winding, the inner ring is indispensable for gaskets with PTFE filler, as outlined by ASME B16.20 standards, and is highly recommended for graphite fillers as well. Adhering to the DIN 2699 standard, this sophisticated design is optimal for both raised and flat-faced flanges. The external ring not only bolsters radial strength to prevent blowout but also serves as a vital compression stop. Created primarily from carbon steel—painted or zinc-plated to resist corrosion—or optionally from alloys for high-temperature and demanding applications, this gasket epitomizes durability and reliability.
