Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This spiral wound gasket is engineered with a robust construction featuring a solid outer and inner ring. The inclusion of an inner ring is an intelligent enhancement designed to supercharge gasket performance. It ensures accurate centering on the flange face, safeguarding the gasket from the risk of imploding into the pipe during installation. This crucial component acts as a bulwark, defending the sealing element against extreme temperatures and aggressive mediums. It adeptly fills the void between flanges, thereby preventing flange erosion, and significantly mitigates the risk of failure. Crafted from the same alloy as the winding, the inner ring conforms to the esteemed DIN 2699 standard (German) that mandates inner rings in all spiral wound gaskets. According to ASME B16.20 standards, inner rings are indispensable for gaskets with PTFE filler and are highly recommended for those with graphite fillers. This profile excels in both raised and flat-faced flanges. Additionally, the external guide ring fortifies the gasket with extra radial strength to avert blowout, while serving as a compression stop. Typically, the outer ring is made from durable carbon steel, finished with paint or zinc plating for corrosion resistance, although alloys are available for high-temperature and severe medium applications.
