Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing the exceptional CS Spiral Winding Gasket with Graphite Filler and SS304 Design from Ningbo Dongheng Sealing Co., Ltd. This innovative spiral wound gasket is engineered with precision, featuring a robust construction with both solid outer and inner rings. An inner ring is meticulously inserted to significantly boost gasket performance, ensuring optimal functionality. The addition of an inner ring is a strategic enhancement, designed to prevent the potential implosion of the gasket into the pipe during installation. It provides vital protection for the sealing element against extreme temperatures and harsh mediums, fills the void between flanges to safeguard against flange erosion, and significantly lowers the risk of failure. Crafted from the same alloy as the winding, the inner ring adheres to the stringent DIN 2699 standard (German) which necessitates inner rings in all spiral wound gaskets. For gaskets with PTFE fillers, the ASME B16.20 standards mandate the inclusion of inner rings, which are equally vital for those with graphite fillers. This versatile profile is expertly suited for use in both raised and flat-faced flanges. Enhancing durability, the external guide ring accurately centers the gasket on the flange face and offers additional radial strength to avert gasket blowout. It also serves as a compression stop, ensuring reliable performance. Typically, the outer ring is crafted from carbon steel, painted or zinc-plated to resist corrosion, but can be made from alloys for demanding high-temperature and severe medium applications.
