Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing the spiral wound gasket, an engineering marvel designed for optimal sealing efficiency. This remarkable gasket is equipped with robust outer and inner rings. The thoughtfully integrated inner ring significantly enhances gasket performance by accurately centering it on the flange face. This crucial component serves multiple purposes: it prevents the gasket from collapsing into the pipe during installation, shields the sealing element from extreme temperatures, fills the void between flanges to avert flange erosion, and minimizes the risk of failure. The inner ring, typically crafted from the same alloy as the winding, ensures unparalleled compatibility and durability. Adhering to the stringent DIN 2699 standard (German), inner rings are mandatory in all spiral wound gaskets. According to ASME B16.20 standards, inner rings are essential for gaskets with PTFE fillers and highly beneficial for those with graphite fillers. This sophisticated profile is ideally suited for both raised and flat-faced flanges. The external guide ring adds extra radial strength, preventing gasket blowout and acting as a compression stop, ensuring unmatched resilience and reliability. Often constructed from carbon steel, which is painted or zinc-plated to resist corrosion, the outer ring can also be crafted from alloys for elevated temperature and more demanding medium applications.
