SPIRAL WOUND GASKET
Product Type: XINSEN-SD
Features:
Discover the remarkable engineering behind our spiral wound gasket, designed to offer unmatched durability and reliability. Featuring a robust outer and inner ring configuration, this gasket is equipped with a strategically inserted inner ring to significantly boost performance. The inner ring serves as a safeguard, preventing the gasket from collapsing into the pipe during installation, shielding the sealing element from extreme temperatures and harsh conditions, and effectively filling the gap between flanges to thwart flange erosion. This enhancement minimizes the risk of failure, ensuring dependable performance under pressure. Crafted typically from the same alloy as the winding, the inner ring adheres to the rigorous DIN 2699 standard, requiring its presence in all spiral wound gaskets. For gaskets with PTFE fillers, as per ASME B16.20 standards, the inner ring is indispensable and highly recommended for graphite fillers. This versatile profile is adeptly suited for both raised and flat-faced flanges. The external guide ring further adds radial strength, safeguarding against blowouts and serving as a compression limiter. Often constructed from carbon steel, which can be painted or zinc-plated for corrosion resistance, the outer ring can also be made from alloys to withstand higher temperatures and more aggressive media.
