Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing the revolutionary Monel Spiral Gasket with 316 Inner Ring and Graphite Winding from Ningbo Dongheng Sealing Co., Ltd., a marvel engineered to perfection. This innovative gasket stands out with its robust design, featuring a meticulously crafted inner ring that significantly enhances its performance. The incorporation of the inner ring is a game-changer, safeguarding the gasket during installation by preventing implosion and offering formidable protection against extreme temperatures and aggressive environments. The external guide ring ensures impeccable centering on the flange face, effectively filling the void between flanges to mitigate the risk of erosion, thereby drastically reducing the chance of gasket failure. Engineered from the same premium-grade alloy as the winding, the inner ring complies with the rigorous DIN 2699 standard, cementing its necessity in all spiral wound gaskets. Recognizing the critical importance of inner rings, ASME B16.20 standards demand their inclusion for gaskets with PTFE and graphite fillers. This adaptable profile excels in applications with raised and flat-faced flanges, where the external ring enhances radial strength to prevent blowout and serves as an essential compression limiter. The outer ring, typically crafted from either painted or zinc-plated carbon steel to combat corrosion, can be customized with alloys for resilience against higher temperatures and more challenging environments.
