Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Experience the unparalleled excellence of our spiral wound gasket, meticulously designed with a robust outer and inner ring. For enhanced performance, an inner ring has been thoughtfully integrated to ensure optimal gasket efficiency. It serves to accurately center the gasket on the flange face, preventing implosions into the pipe during installation. This ingenious addition protects the sealing element from extreme temperatures and diverse mediums, fills voids between flanges to avert erosion, and significantly reduces the risk of failure. The inner ring is typically crafted from the same high-quality alloy as the winding, adhering to the rigorous DIN 2699 standard from Germany, which mandates inner rings in all spiral wound gaskets. According to ASME B16.20 standards, inner rings are essential for gaskets with PTFE filler and highly recommended for those with graphite fillers. Designed for use in raised and flat faced flanges, the external guide ring provides superior radial strength to prevent blowout and acts as a reliable compression stop. Often made of painted or zinc-plated carbon steel to combat corrosion, the outer ring can also be constructed from specialized alloys for high-temperature and severe medium applications.
