Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Indulge in the excellent craftsmanship of this spiral wound gasket, which boasts a robust outer and inner ring for superior performance. We've ingeniously inserted an inner ring to elevate its functionality, ensuring precise centering on flange faces through an expertly designed external guide ring. This inner addition serves multiple purposes: it fortifies the gasket against implosions during installation, shields the sealing element from extreme conditions, and adeptly fills voids to prevent flange erosion. Moreover, it significantly minimizes the risk of failure. Crafted typically from the same alloy as the winding, this inner ring aligns with the DIN 2699 German standards that mandate inner rings for all spiral wound gaskets. According to ASME B16.20 standards, it's a requisite for gaskets with PTFE filler and highly recommended for those with graphite fillers. This flawless profile shines in both raised and flat-faced flanges. The outer ring, often forged from carbon steel with meticulous painting or zinc plating for corrosion resistance, can also be constructed from special alloys for those demanding high-temperature and severe medium applications. It provides exceptional radial strength, thwarting gasket blowout while functioning as a reliable compression stop. A true testament to engineering excellence, this profile is your go-to for raised and flat-faced flanges.
