Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Immerse in the world of sophisticated sealing solutions with our spiral wound gasket, equipped with a robust outer and inner ring. An expertly inserted inner ring elevates the gasket's performance, ensuring its precise centering on the flange face with an external guide ring. This meticulous design prevents potential gasket implosion into the pipe during installation, shields the sealing element from extreme temperatures and harsh mediums, and seamlessly fills voids between flanges to guard against flange erosion, thereby significantly reducing the risk of failure. Crafted, usually, from the same alloy as the winding, the inner ring plays a crucial role for gaskets with PTFE fillers, as per ASME B16.20 standards, and for graphite fillers, as recognized by DIN 2699 standards in Germany. This profile finds its perfect application in both raised and flat-faced flanges. The formidable external ring not only strengthens against radial forces, preventing blowout, but also functions as a compression limiter. Generally constructed from corrosion-resistant carbon steel—painted or zinc-plated—this outer ring can also be composed of advanced alloys for applications involving higher temperatures and severe mediums, ensuring durability and reliability.
