SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
Introducing a remarkable spiral wound gasket equipped with robust outer and inner rings. The inclusion of an inner ring is a strategic enhancement to boost gasket performance and ensure flawless alignment with the flange face through an external guide ring. This innovation prevents gasket implosion into pipes during installation, shields the sealing element from extreme temperatures and harsh mediums, and fills voids to protect against flange erosion. Furthermore, it significantly decreases the potential for gasket failure. Typically, the inner ring mirrors the alloy of the winding as per the stringent DIN 2699 standard, a German specification mandating inner rings in all spiral wound gaskets. The ASME B16.20 standards require inner rings for gaskets with PTFE fillers and highlight their importance for graphite fillers. Designed for both raised and flat-faced flanges, the external ring offers additional radial fortitude, averting blowouts, and serves as a compression stop. This component is often crafted from carbon steel with protective paint or zinc plating to ward off corrosion, yet can be substituted with superior alloys for high-temperature and severe conditions.
