SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This premium spiral wound gasket is ingeniously crafted with a robust solid outer and inner ring. For enhanced performance, an inner ring is meticulously inserted, elevating the gasket's operational efficiency. This vital component serves multiple protective functions: it prevents the gasket from imploding into the pipe during installation, safeguards the sealing element from extreme temperatures and aggressive mediums, and fills the void between flanges to combat flange erosion and reduce failure risks. Typically, the inner ring is composed of the same resilient alloy as the winding, ensuring compatibility and durability as dictated by the German DIN 2699 standard. According to the prestigious ASME B16.20 standards, inner rings are indispensable for gaskets filled with PTFE and are deemed crucial for graphite fillers. This distinctive profile is ideally suited for use in raised and flat-faced flanges. The external guide ring provides essential radial strength, preventing blowouts and acting as a compression limit. Commonly made from carbon steel-painted or zinc-plated to resist corrosion-the outer ring can also be crafted from high-performance alloys for elevated temperature and more demanding applications.
