Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing our cutting-edge spiral wound gasket, meticulously designed with a robust solid outer and inner ring structure. This innovative gasket includes an expertly inserted inner ring, which amplifies performance by ensuring precise centering on the flange face. The inner ring's primary purpose is to safeguard the sealing element from extreme temperatures and harsh mediums, effectively preventing gasket implosion during installation. Furthermore, it fills the void between flanges, thus averting erosion and reducing failure risks. Crafted from identical alloy as the winding, the inner ring complies with the stringent DIN 2699 German standard mandating its inclusion in all spiral wound gaskets. Essential for gaskets with PTFE filler under ASME B16.20 standards, and highly recommended for graphite fillers, this profile is ideally suited for both raised and flat faced flanges. The external guide ring enhances radial strength, averting blowouts and serving as a reliable compression stop. Often manufactured from corrosion-resistant carbon steel, the outer ring can also be composed of specialized alloys for applications demanding higher temperature resilience and compatibility with severe mediums.
