Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Crafted with precision and expertise, this spiral wound gasket boasts a robust structure with a solid outer and inner ring. In a thoughtful enhancement, an inner ring is strategically inserted to bolster gasket performance while an external guide ring ensures precise centering on the flange face. This ingenious design serves multiple functions: the inner ring prevents implosion during installation, shields the sealing element from extreme conditions, fills gaps between flanges to avert erosion, and minimizes the risk of failure. Typically crafted from the same alloy as the winding, the inner ring complies with the esteemed DIN 2699 German standard, which mandates inner rings for all spiral wound gaskets. According to ASME B16.20 standards, inner rings are essential for gaskets with PTFE filler and hold significant value for those with graphite fillers. This versatile profile suits both raised and flat-faced flanges. The external ring not only enhances radial strength to thwart blowout but also acts as a reliable compression stop. Generally constructed from carbon steel, which is either painted or zinc-plated to thwart corrosion, the outer ring can also be made from alloys for challenging high-temperature or severe medium applications, showcasing its adaptability.
