Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Crafted with precision, this spiral wound gasket is reinforced with robust outer and inner rings for enhanced durability. The introduction of an internal ring is a strategic enhancement to bolster gasket performance, ensuring precise placement on the flange face with the external guide ring. This inner ring acts as a safeguard, preventing potential implosion into the pipe during installation and shielding the sealing component from extreme conditions and media. It bridges any gaps between flanges, mitigating erosion and minimizing failure risks. Typically, the inner ring mirrors the winding's alloy, adhering to the DIN 2699 German standard which mandates inner rings in all spiral wound gaskets. According to ASME B16.20 standards, PTFE fillers necessitate the inclusion of inner rings, and they are deemed essential for graphite fillers. This gasket profile excels in raised and flat-faced flange applications, with the external ring providing added radial strength to avert blowout, doubling as a compression limiter. The outer ring, usually constructed from carbon steel with anti-corrosive coatings, may also be crafted from special alloys for high-temperature and demanding environments.
