Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Indulge in the superior engineering of our spiral wound gasket, crafted with precision to include a robust solid outer and inner ring. The addition of an inner ring is a masterstroke in enhancing gasket performance, while the external guide ring ensures impeccable centering on the flange face. The inner ring is an essential safeguard, preventing implosion into the pipe during installation, protecting the sealing element from the extremities of temperature and medium, and expertly filling the flange void to avert erosion. It significantly reduces the risk of failure, with its composition ideally matching the winding's alloy. As per the revered DIN 2699 (German) standards, inner rings are a requisite in all spiral wound gaskets. For those utilizing PTFE filler, they're mandatory under ASME B16.20 standards and similarly critical when using graphite fillers. This optimized profile is adeptly suited for both raised and flat-faced flanges. The external ring, a bastion of radial strength, thwarts gasket blowout and functions brilliantly as a compression stop. Typically crafted from carbon steel—with optional painted or zinc-plated finishes to mitigate corrosion—or from alloys for enduring higher temperatures and more severe medium challenges, this outer ring is as versatile as it is durable.
