Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This remarkable spiral wound gasket is designed with both a solid outer and inner ring, but with a unique enhancement—an inserted inner ring that elevates the gasket's performance to unparalleled heights. The inclusion of an external guide ring ensures precise centering on the flange face. This crucial inner ring is strategically added to avert any possibility of the gasket collapsing into the pipe during installation. It also serves to shield the sealing element from extreme temperatures and harsh mediums, effectively filling the void between flanges to prevent flange erosion and reduce the risk of failure. Crafted typically from the same alloy as the winding, this inner ring meets the stringent DIN 2699 German standards, which mandate inner rings in all spiral wound gaskets. ASME B16.20 standards also require inner rings for gaskets with PTFE filler, considering them vital for those with graphite fillers. It is ideally suited for use in both raised and flat-faced flanges. Furthermore, the robust external ring provides additional radial strength to guard against gasket blowout and functions as a compression stop, ensuring reliability in performance. Typically composed of carbon steel to avoid corrosion through painting or zinc plating, the outer ring is adaptable for high-temperature and more extreme medium applications, potentially crafted from alloys for such demanding environments.
