Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing our exceptional spiral wound gasket, engineered with precision to include both robust outer and inner rings, ensuring superior performance. The incorporation of an inner ring significantly enhances the gasket's durability and prevents implosion into the pipe during installation, shielding the sealing element from severe temperatures and corrosive mediums. It effectively fills the void between flanges, thereby protecting against flange erosion and mitigating the risk of failure. Crafted typically from the same alloy as the winding, the inner ring adheres to the stringent DIN 2699 and ASME B16.20 standards, making it indispensable for gaskets with PTFE or graphite fillers. Perfectly suited for both raised and flat-faced flanges, the external guide ring provides crucial radial strength, averting gasket blowout and serving as a vital compression stop. Generally fabricated from carbon steel—with optional painting or zinc plating for corrosion resistance—it can also be customized from specialized alloys to withstand extreme temperatures and challenging mediums.
