Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This exceptional spiral wound gasket is engineered with a robust outer and inner ring for unparalleled sealing excellence. An added inner ring significantly enhances gasket performance by ensuring precise alignment on flange faces while safeguarding the gasket against implosion during installation. This inner ring, mirroring the winding's alloy, also shields the sealing element from extreme conditions, fills voids between flanges to avert erosion, and minimizes the risk of failure. Complying with the esteemed DIN 2699 German standard, inner rings are mandatory for all spiral wound gaskets. For gaskets employing PTFE fillers, ASME B16.20 standards necessitate these inner rings, which are equally vital for graphite fillers. Perfectly suited for raised and flat-faced flanges, the external guide ring offers steadfast radial strength, preventing gasket blowout and serving as a dependable compression stop. Typically crafted from painted or zinc-plated carbon steel to resist corrosion, the outer ring can also be fashioned from alloys suitable for high-temperature and challenging medium applications, ensuring durability and reliability.
