Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing the high-performance spiral wound gasket from Ningbo Dongheng Sealing Co., Ltd., engineered with precision to deliver exceptional sealing capabilities. This cutting-edge Flexitallic Gasket with PTFE Filler and Spiral Winding Design boasts a robust construction, featuring solid outer and inner rings. Enhanced performance is achieved with an expertly inserted inner ring, which plays a critical role in boosting the gasket's reliability and longevity. This inner ring serves multiple vital functions: it secures the gasket in place during installation, shielding it from harsh temperatures and corrosive substances. It adeptly fills the gap between flanges, preventing flange erosion and significantly reducing the risk of gasket failure. Crafted to meet the eminent DIN 2699 (German) standard, these inner rings are indispensable for PTFE filler gaskets as per ASME B16.20 standards and are crucial for graphite fillers. The profile of this remarkable gasket is tailored for use with raised and flat-faced flanges, with the external ring providing outstanding radial strength that minimizes the risk of blowouts while serving as a reliable compression stop. Typically constructed from painted or zinc-plated carbon steel to resist corrosion, the outer ring can be customized with advanced alloys to suit high-temperature and demanding applications. This ensures that the gasket performs optimally under severe conditions, offering a durable and trustworthy solution for your sealing needs.
