SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This spiral wound gasket, boasting solid outer and inner rings, is meticulously engineered to elevate your sealing performance. The insertion of an inner ring is a masterstroke, ensuring enhanced gasket functionality by centering it precisely on the flange face. This ingenious design prevents implosion into pipes during installation, shields the sealing element from extreme temperatures and harsh mediums, and fills the gap between flanges to thwart erosion, thereby significantly reducing failure risks. Constructed typically from the same alloy as the winding, the inner ring meets the stringent DIN 2699 German standards, which mandate inner rings for all spiral wound gaskets. Adhering to ASME B16.20 standards, the inner ring is essential for PTFE fillers and crucial for graphite fillers. This profile is perfectly suited for both raised and flat-faced flanges. The robust external ring enhances radial strength, protecting against blowouts and doubling as a compression stop. Commonly crafted from carbon steel, which is either painted or zinc-plated to prevent corrosion, the outer ring can also be made from specialized alloys for high-temperature and severe medium applications.
