Product Description

Introducing the SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This ingeniously designed spiral wound gasket boasts a robust solid outer and inner ring structure. Uniquely, an inner ring is seamlessly integrated to significantly optimize performance. This inner marvel ensures flawless gasket alignment on the flange face, safeguarding against implosion into the pipe during installation. It protects the sealing element from extreme conditions, fills flange voids to prevent erosion, and minimizes failure risks. Crafted usually from the same alloy as the winding, the inner ring complies with German DIN 2699 standards for all spiral wound gaskets and is a critical element for PTFE fillers as per ASME B16.20 standards. This design thrives on raised and flat-faced flanges. The external guide ring enhances radial strength, preventing gasket blowout while serving as a vital compression stop. Typically fashioned from carbon steel (painted or zinc plated for corrosion resistance), the outer ring can also be made from alloys for superior performance in higher temperature and harsh mediums.
