SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing the groundbreaking Spiral Wound Metal Gasket with Monel Inner Ring and Mica Winding from Ningbo Dongheng Sealing Co., Ltd., a marvel of engineering brilliance. This gasket is expertly designed with an innovative Monel inner ring, a vital component that elevates both the performance and dependability of the gasket. The Monel inner ring ensures perfect alignment on the flange face, eliminating misalignment risks that could lead to system failures. It robustly safeguards against collapse during installation and offers exceptional defense against extreme temperatures and harsh chemicals, preserving its structural integrity effortlessly. As it fills the flange void, it minimizes erosion risks and dramatically reduces gasket failure chances. Crafted from the same premium alloy as the winding, it caters to the stringent requirements of the DIN 2699 standard, mandating its inclusion in all spiral wound gaskets. Its importance is further recognized by ASME B16.20 standards, especially in gaskets equipped with PTFE fillers, where the inner ring is essential for maintaining the graphite fillers' effectiveness. This versatile gasket design is perfect for both raised and flat-faced flanges. The external guide ring contributes significantly to radial strength, effectively preventing blowouts and serving as a crucial compression stop, boosting the gasket's overall durability. Typically made from painted or zinc-plated carbon steel to combat corrosion, this outer ring can also be customized with special alloys to endure higher temperatures and meet the demands of more challenging environments.
