Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Experience the excellence of our spiral wound gasket, meticulously crafted with a robust solid outer ring and an inner ring, enhancing its performance. Our gasket's inner ring is strategically placed to avert any risk of implosion into the pipe during installation. It serves as a formidable shield, safeguarding the sealing element against extreme temperatures and harsh media, while effectively filling any voids between flanges to prevent erosion and minimize failure chances. Typically, our inner rings are composed of the same high-grade alloy as the winding, complying with the DIN 2699 standard (German), which mandates inner rings in all spiral wound gaskets. For those with PTFE fillers, ASME B16.20 standards necessitate inner rings, which are also deemed crucial for graphite fillers. This ingenious profile is ideal for use in both raised and flat-faced flanges. The external guide ring precisely centers the gasket on the flange face, furnishing additional radial strength to prevent blowouts and acting as a reliable compression stop. Often constructed from carbon steel to resist corrosion, our outer rings can also be forged from specialized alloys for higher temperature endurance and more severe media applications, ensuring unparalleled reliability.
