Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing a revolutionary spiral wound gasket with an expertly engineered solid outer and inner ring, designed to elevate gasket performance to unparalleled heights. The inclusion of a meticulously crafted inner ring serves to enhance the gasket's durability, ensuring it is securely centered on the flange face with pinpoint precision by an external guide ring. This thoughtful addition of an inner ring is crucial, as it safeguards against potential gasket implosion during installation, while also protecting the sealing element from the harshest temperatures and media. It effectively fills the void between flanges, preventing erosion and significantly reducing the risk of failure. Typically, the inner ring is composed of the same robust alloy as the winding, adhering to the prestigious DIN 2699 standard (German) which mandates inner rings for all spiral wound gaskets. According to the esteemed ASME B16.20 standards, inner rings are essential for gaskets with PTFE filler and are highly recommended for those with graphite fillers. This innovative profile is perfectly suited for use in both raised and flat faced flanges. The formidable external ring imparts additional radial strength, acting as a stalwart barrier against gasket blowout while serving as a reliable compression stop. Often crafted from carbon steel, which is painted or zinc plated to resist corrosion, the outer ring can also be fashioned from alloys to withstand higher temperatures and more demanding media applications.
