Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This innovative spiral wound gasket is engineered with a robust outer and inner ring for superior performance. The addition of an inner ring significantly enhances the gasket's capability, ensuring precise centering on the flange face and safeguarding against potential implosion into the pipe during installation. This sophisticated feature also protects the sealing element from extreme temperatures and aggressive mediums, fills voids to prevent flange erosion, and minimizes the risk of failure. Crafted from the same alloy as the winding, the inner ring complies with DIN 2699 standards and is essential for PTFE fillers under ASME B16.20 and highly recommended for graphite fillers. This versatile profile excels with both raised and flat-faced flanges. Furthermore, the external guide ring adds critical radial strength to avert blowouts and functions as a compression stop. While commonly constructed from carbon steel—with optional painting or zinc plating for corrosion resistance—outer rings can also be produced from specialized alloys to endure elevated temperatures and more demanding environments.
