SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
Introducing our innovative spiral wound gasket, meticulously crafted with robust outer and inner rings. The integration of an inner ring significantly enhances performance, acting to precisely center the gasket on the flange face. This crucial component safeguards against potential implosion into the pipe during installation, shields the sealing element from adverse temperatures and materials, and ensures the void between flanges is securely filled—preventing flange erosion while diminishing the risk of operational failure. Typically, the inner ring shares the same alloy as the winding, adhering to the German DIN 2699 standard which mandates this feature in all spiral wound gaskets. For gaskets filled with PTFE, the ASME B16.20 standards necessitate inner rings, underscoring their importance in graphite fillers as well. This exceptional gasket design is ideally suited for raised and flat-faced flanges. The durable external ring not only imparts additional radial strength to avert blowouts but also functions as a compression stop. Constructed often from carbon steel, painted or zinc-plated to resist corrosion, the outer ring can also be forged from specialized alloys to withstand elevated temperatures and rigorous applications.
