Product Description
SPIRAL WOUND GASKET
Product Description

Product Type: XINSEN-SD
Features:
This exceptional spiral wound gasket, meticulously crafted with a robust outer and inner ring, is engineered to deliver unparalleled performance. The strategically inserted inner ring not only enhances the gasket's durability but also serves multiple pivotal functions. It prevents implosion into the pipe during installation, shields the sealing element from extreme temperatures and aggressive mediums, and effectively fills the void between flanges to avert flange erosion. Its inclusion markedly reduces the risk of failure. Conforming to the esteemed DIN 2699 standard, the inner ring is an essential feature in all spiral wound gaskets. As mandated by ASME B16.20 standards, an inner ring is crucial for gaskets with PTFE fillers and holds significant importance for those with graphite fillers. This versatile profile adapts seamlessly to both raised and flat-faced flanges. The sturdy external guide ring not only ensures precise centering on the flange face but also provides added radial strength, preventing blowout and acting as a reliable compression stop. Expertly crafted, the outer ring is typically made of carbon steel, which is either painted or zinc-plated to resist corrosion, although it can be tailored with other alloys for applications involving higher temperatures and more demanding mediums.
