Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing an exceptional spiral wound gasket from Ningbo Dongheng Sealing Co., Ltd., featuring an ingenious design that includes a cutting-edge Monel inner ring, encased in a durable graphite assembly. This innovative inner ring not only elevates gasket performance to new heights but also fortifies the gasket against potential damage during installation by maintaining its integrity amidst extreme thermal conditions and aggressive mediums. By effectively bridging the gap between flanges, it minimizes erosion risks and significantly enhances operational reliability. Manufactured using the highest quality alloys, the inner ring complies with the rigorous DIN 2699 standard, underscoring its necessity in all spiral wound gaskets. Additionally, ASME B16.20 standards mandate inner rings for gaskets with PTFE and graphite fillers, due to their critical role in securing gasket performance. This versatile design is perfect for both raised and flat-faced flanges, with its outer guide ring not only ensuring perfect alignment but also amplifying radial strength to prevent blowouts, acting as a key compression stop. Typically crafted from painted or zinc-plated carbon steel to resist corrosion, the outer ring can also be customized with special alloys for enhanced thermal resistance and durability in challenging environments.
