Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing our premium spiral wound gasket, meticulously engineered to feature a robust outer and inner ring configuration. The expertly inserted inner ring significantly enhances the gasket's performance by ensuring precise centering on the flange face via the external guide ring. This critical addition of the inner ring is designed to avert potential gasket implosion into the pipeline during setup, thereby shielding the sealing element from harsh temperature variations and demanding mediums. It adeptly fills the gap between flanges to thwart flange erosion and minimizes the risk of operational failure. Crafted typically from the same alloy as the winding, the inner ring complies with the stringent standards of DIN 2699 and ASME B16.20, essential for gaskets with PTFE and highly recommended for those with graphite fillers. Ideal for both raised and flat-faced flanges, the external ring supplements with additional radial strength, preventing any gasket blowouts and serving as a dependable compression stop. The outer ring is commonly manufactured from carbon steel—painted or zinc-plated to resist corrosion—but can also be crafted from specialized alloys to cater to higher temperature criteria and more intense medium applications.
