Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
The spiral wound gasket is a marvel of advanced sealing technology, ingeniously designed with a sturdy outer and inner ring to bolster its performance. An inner ring has been strategically inserted to not only enhance the gasket's stability but also to precisely center it on the flange face with an external guide ring. This vital addition ensures the gasket remains secure and intact during installation, adeptly shielding the sealing element from extreme temperatures and corrosive mediums. It ingeniously fills any voids between flanges, warding off potential erosion and significantly reducing the risk of gasket failure. The inner ring, crafted from the same durable alloy as the winding, complies with the stringent DIN 2699 standard, a testament to its robust design. For gaskets with PTFE filler, ASME B16.20 standards dictate the necessity of inner rings, which are equally recommended for graphite fillers. This versatile profile securely fits into raised and flat-faced flanges, with an external ring adding further radial strength to avert blowouts, while acting as a reliable compression stop. Typically, the outer ring is formed from resilient carbon steel, optionally painted or zinc-plated for corrosion resistance, but can also be crafted from specialized alloys for high-temperature environments and challenging mediums.
