Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Experience the pinnacle of sealing technology with our spiral wound gasket, featuring both a robust outer and inner ring for unparalleled performance. The strategically inserted inner ring not only enhances the gasket's durability but also ensures precise centering on flange faces with its external guide ring. Essential in preventing gasket implosion during installation, this inner ring safeguards the sealing element from extreme conditions and media. It fills the flange void, preventing erosion and reducing failure risks. Crafted typically from the same alloy as the winding, the inner ring complies with the German DIN 2699 standard, and its inclusion is critical for gaskets with PTFE filler per ASME B16.20 standards, and highly recommended for graphite fillers. This innovative design thrives in both raised and flat-faced flanges. The outer ring, which can be carbon steel or alloy for high-temperature and severe medium conditions, imparts additional radial strength to thwart gasket blowout and serves as a compression limiter.
