Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Crafted with precision, this spiral wound gasket boasts a robust design featuring solid outer and inner rings. To elevate its performance, an inner ring is meticulously incorporated, ensuring flawless gasket function and precise alignment upon installation by means of an external guide ring. The inner ring plays a pivotal role; it prevents potential implosion into the piping system during setup, shields the sealing element from extreme temperatures and aggressive mediums, fills the void between flanges to thwart flange erosion, and minimizes the risk of failure. Typically, the inner ring matches the alloy of the winding, adhering to the DIN 2699 standard (German) which mandates inner rings in all spiral wound gaskets. For gaskets with PTFE fillers, ASME B16.20 standards necessitate the presence of inner rings, deeming them crucial for graphite fillers as well. This design is ideally suited for both raised and flat-faced flanges. The inclusion of an external ring grants additional radial strength, averting gasket blowouts and serving as a compression limiter. This design, crafted for raised and flat-faced flanges, ensures durability and reliability. Commonly made of carbon steel (either painted or zinc plated to resist corrosion), the outer ring can also be constructed from alloys tailored for high-temperature and demanding medium applications.
