Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Experience the pinnacle of sealing technology with our spiral wound gasket, featuring an impeccably engineered solid outer and inner ring. This design includes an innovative inner ring that significantly boosts gasket performance. It ensures precise centering on the flange face with an external guide ring. The strategic inclusion of the inner ring serves multiple purposes: it prevents potential implosion into the pipe during installation, safeguards the sealing element from adverse temperatures and harsh environments, and fills voids between flanges to avert erosion. Plus, it crucially reduces the risk of gasket failure. Crafted typically from the same robust alloy as the winding, the inner ring follows the rigorous DIN 2699 standard for all spiral wound gaskets and is mandatory for PTFE fillers under ASME B16.20 standards, being especially significant for graphite fillers. Tailored for raised and flat-faced flanges, this gasket type benefits from an external ring that provides additional radial strength, preventing blowouts and doubling as a compression stop. While the outer ring is generally made of corrosion-resistant carbon steel, options for alloy construction are available for higher temperature and more demanding applications.
