Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing the ASME B16.20 Spiral Gasket with 304 Inner Ring and Mica—a marvel of engineering by Ningbo Dongheng Sealing Co., Ltd. This advanced spiral wound gasket features a robust outer and an innovative inner ring, both ingeniously designed to boost performance and reliability. Its inner ring is crucial, ensuring precise centering on the flange face and preventing the gasket from collapsing into the pipe. It acts as a shield, safeguarding the sealing element from severe temperatures and aggressive mediums. By filling the void between flanges, it prevents flange erosion and significantly reduces the risk of failure, especially in high-stakes installations. The inner ring, crafted from the same alloy as the winding, adheres to the rigorous DIN 2699 standard, mandating its use in all spiral wound gaskets. For gaskets with PTFE fillers, the ASME B16.20 standards underscore the inner ring's necessity, while it's deemed vital for graphite fillers too. This gasket profile excels in both raised and flat-faced flanges. The external guide ring, often of carbon steel, provides enhanced radial strength to avert blowouts and doubles as a compression stop. It's available in variations like painted or zinc-plated carbon steel to counteract corrosion, or in alloys for high-temperature, demanding applications. Elevate your sealing solutions with this exceptional product.
