Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing a top-tier spiral wound gasket, engineered with both a robust outer and inner ring. The innovative inner ring enhances performance, ensuring that during installation, it doesn't implode into the pipe. It effectively shields the sealing element from extreme conditions, fills the flange void to prevent erosion, and significantly minimizes the risk of failure. Made from the same premium alloy as the winding, this inner ring aligns with the stringent DIN 2699 German standards and is essential for gaskets with PTFE fillers as per ASME B16.20 standards, also playing a crucial role with graphite fillers. This design is ideal for raised and flat-faced flanges. The external guide ring serves a dual purpose: offering additional radial strength to thwart gasket blowout and acting as a precision compression stop. Crafted often from corrosion-resistant carbon steel, it can also be made from specialized alloys for environments with extreme temperatures or harsh media exposure.
