SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This sophisticated spiral wound gasket boasts a robust construction with both a solid outer and inner ring. The incorporation of an internal ring is a strategic enhancement, elevating gasket performance by ensuring precise alignment on the flange face. This crucial inner ring mitigates risks of gasket collapse during installation, shields the sealing element from extreme conditions, bridges the flange gap to avert erosion, and minimizes failure risk. Crafted typically from the same alloy as the winding, the inner ring aligns with DIN 2699 standards, mandating inner rings in all spiral wound gaskets. For gaskets with PTFE fillers, ASME B16.20 standards necessitate inner rings, proving vital for graphite fillers too. Ideally suited for raised and flat-faced flanges, the external ring imparts additional radial strength to thwart blowouts and serves as a compression stop. Often fabricated from painted or zinc-plated carbon steel to resist corrosion, the outer ring may also be made from alloys for enduring higher temperatures and severe environments.
