Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This innovative spiral wound gasket is engineered with a robust solid outer and inner ring, designed to elevate gasket performance significantly. The inclusion of an inner ring enhances the structural integrity, precisely centering the gasket on the flange face and safeguarding the sealing element from harsh temperatures and media. Its primary function is to fill the void between flanges, preventing erosion and reducing potential failure risks. Fabricated from the same alloy as the winding for optimal compatibility, our inner ring complies with the DIN 2699 standard. This standard mandates the inclusion of inner rings in all spiral wound gaskets, especially when using PTFE fillers as per ASME B16.20 standards, and is crucial for graphite fillers. Ideal for both raised and flat faced flanges, the external guide ring offers additional radial strength, serving as a compression stop to avert gasket blowout. Typically made of carbon steel with anti-corrosion finishes or high-temperature alloys, the outer ring ensures reliable performance in challenging environments.
