Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Experience unparalleled sealing performance with our spiral wound gasket, meticulously engineered for perfection. Crafted with a robust solid outer and inner ring, this gasket includes an inner ring designed to boost performance. The inner ring serves multiple purposes: it prevents any implosion into the pipe during installation, offers protection against extreme temperatures and mediums, fills the void between flanges to avert erosion, and significantly reduces the risk of failure. Typically, the inner ring shares the same alloy composition as the winding, adhering to the German DIN 2699 standard that prescribes inner rings for all spiral wound gaskets. For gaskets with PTFE filler, inner rings are a necessity as per ASME B16.20 standards and are vital for those with graphite fillers. This exceptional profile is ideally applied to raised and flat-faced flanges. The external guide ring augments radial strength to prevent blowouts and acts as a precise compression stop. Commonly manufactured from carbon steel—either painted or zinc-plated to resist corrosion—it can also be crafted from alloys for high-temperature and more demanding mediums. This innovative design ensures reliable performance in both raised and flat-faced flanges, making it an indispensable choice for sealing needs.
