Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing the Graphite Metal Gasket with Spiral Winding and SS304 Inner Ring, a marvel of engineering excellence by Ningbo Dongheng Sealing Co., Ltd. This gasket distinguishes itself with a robust, solid outer and inner ring, meticulously designed for unparalleled performance. The inclusion of an expertly crafted inner ring elevates the gasket's efficacy, providing steadfast protection during installation by preventing the gasket from imploding into the pipe. It acts as a guardian against extreme temperatures and hostile mediums, ensuring flawless operation. This inner ring also secures the integrity of the sealing element, minimizes flange erosion, and significantly reduces failure risks. Adhering to the renowned DIN 2699 and ASME B16.20 standards, it is indispensable for gaskets with PTFE and graphite fillers. Typically constructed from a matching alloy to the winding, this element finds its optimal application in raised and flat-faced flanges. Enhancing the design further, an external guide ring expertly centers the gasket, offering additional radial strength to avert any blowout. It simultaneously serves as a compression stop, crafted from carbon steel—painted or zinc-plated to resist corrosion—or even high-performance alloys for extreme conditions. This construction is ideal for use in both raised and flat-faced flanges, promising reliability and safety under the most demanding circumstances.
