Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing our premium Flexitallic Spiral Gasket with Mica Filler and SS316 Winding, an engineering marvel designed by Ningbo Dongheng Sealing Co., Ltd. This gasket boasts a robust construction with solid outer and inner rings, providing unmatched sealing efficiency and durability. The meticulously inserted inner ring not only elevates the gasket's performance but also ensures precise centering on the flange face for flawless installation. Designed to excel under extreme temperatures and various mediums, the inner ring not only prevents implosion but also shields the sealing element, fills voids to prevent flange erosion, and significantly reduces failure risks. Crafted according to the stringent DIN 2699 standards (German) and aligned with ASME B16.20 standards, the inner ring is indispensable for gaskets with PTFE fillers and highly recommended for graphite fillers. This sophisticated profile is perfect for both raised and flat-faced flanges. To further enhance stability and prevent blowouts, the external guide ring offers additional radial strength and serves as a reliable compression stop. Typically made from carbon steel, which can be painted or zinc-plated for corrosion resistance, or from alloys for higher temperature and severe medium applications, the outer ring is a testament to our commitment to quality and performance.
