Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing our state-of-the-art spiral wound gasket—meticulously engineered with a robust outer and inner ring. The strategic addition of an inner ring elevates gasket performance by precisely positioning the gasket on the flange face and preventing potential implosions into the pipe during installation. This innovation shields the sealing element from extreme temperatures and various mediums, bridges flange gaps to thwart erosion, and significantly mitigates failure risks. Typically crafted from the same premium alloy as the winding, the inner ring adheres to the stringent DIN 2699 standard (German) and is mandated for gaskets with PTFE fillers under the ASME B16.20 standards—it's deemed crucial for graphite fillers. This superior profile seamlessly integrates with raised and flat-faced flanges, offering unmatched durability. Our design incorporates an external guide ring that infuses additional radial strength, serving as a reliable compression stop and preventing gasket blowout. Generally constructed from carbon steel—protected by paint or zinc plating to resist corrosion—or crafted from high-performance alloys for extreme temperatures and severe applications, our outer ring epitomizes resilience.
