Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This remarkable spiral wound gasket is meticulously crafted with a robust solid outer and inner ring construction. Astoundingly, an inner ring has been strategically inserted, significantly boosting the gasket's performance capabilities. Moreover, an expertly engineered external guide ring ensures precise centering of the gasket on the flange face. The inclusion of the inner ring is crucial; it acts as a safeguard, preventing the gasket from imploding into the pipe during installation. It also plays a vital role in shielding the sealing element from harsh temperatures and aggressive media. Furthermore, it fills the void between flanges to avert flange erosion and diminishes the risk of failure. Generally constructed from the same high-quality alloy as the winding, the inner ring aligns with the DIN 2699 standard (German), which mandates inner rings in all spiral wound gaskets. According to the esteemed ASME B16.20 standards, inner rings are essential for gaskets with PTFE filler and are highly recommended for those with graphite fillers. This profile finds its ideal application in both raised and flat-faced flanges. The external ring, providing additional radial strength, is indispensable in preventing gasket blowout and acts as a compression stop. Typically, the outer ring is crafted from durable carbon steel, either painted or zinc-plated to combat corrosion, although it can also be fashioned from alloys to withstand higher temperatures and more challenging media.
