SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This high-performance spiral wound gasket boasts a robust construction with solid outer and inner rings. An inner ring is strategically inserted to significantly enhance gasket performance, ensuring precise centering on the flange face via an external guide ring. The inclusion of the inner ring prevents the gasket from collapsing into the pipe during installation and shields the sealing element from extreme temperatures and harsh mediums. It also fills the gap between flanges, reducing erosion and minimizing the risk of failure. Typically, the inner ring matches the alloy of the winding material. According to DIN 2699 standards (German), inner rings are mandatory for all spiral wound gaskets. ASME B16.20 standards necessitate inner rings for gaskets with PTFE fillers, and they are crucial for graphite fillers. This profile is ideally suited for both raised and flat-faced flanges. The external ring not only provides additional radial strength to prevent gasket blowout but also acts as a compression stop. It is usually made of carbon steel, either painted or zinc-plated to resist corrosion, although alloy options are available for high-temperature and severe medium applications.
