SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
Discover the pinnacle of sealing technology with the DONHONSIL Spiral Wound Gasket, expertly crafted by Ningbo Dongheng Sealing Co., Ltd. This exceptional gasket features a robust solid outer and inner ring, designed to withstand the harshest environments. The innovative inclusion of an inner ring not only enhances gasket performance but also ensures precise centering on the flange face. This prevents any potential implosion into the pipe during installation and offers superior protection against extreme temperatures and aggressive mediums. The inner ring provides essential reinforcement, filling the void between flanges to prevent erosion and significantly reducing the risk of failure. Typically crafted from the same alloy as the winding, the inner ring meets DIN 2699 standards, ensuring reliability in every installation. For applications with PTFE and graphite fillers, compliance with ASME B16.20 standards highlights its critical importance. Ideal for raised and flat faced flanges, the external guide ring adds further radial strength, preventing blowouts and acting as a compression stop. Often made of durable carbon steel with corrosion-resistant coatings, or alloys for high-temperature and severe mediums, the outer ring guarantees unmatched durability and performance.
