Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing a marvel of engineering, the spiral wound gasket with both solid outer and inner rings designed for superior sealing performance. An inner ring is thoughtfully inserted, elevating the gasket's functionality by accurately centering it on the flange face. This vital addition not only prevents potential gasket implosion during installation but also safeguards the sealing element from extreme conditions. It fills the gap between flanges, thereby curbing flange erosion and significantly diminishing the possibility of failure. Crafted to match the winding's alloy, the inner ring aligns with the DIN 2699 standard (German), ensuring inner rings in all spiral wound gaskets. Essential for gaskets with PTFE filler as per ASME B16.20 standards, and crucial for graphite fillers, this design is the epitome of reliability. Typically utilized in raised and flat-faced flanges, the external guide ring enhances radial strength to avert gasket blowout while acting as a compression stop. The outer ring, commonly carbon steel (either painted or zinc plated to deter corrosion), can also be constructed from alloys for high-temperature or severe medium applications. This ensures durability and resilience for the most demanding environments.
