Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This exceptional spiral wound gasket is engineered with both solid outer and inner rings for unparalleled performance. The inclusion of an expertly inserted inner ring dramatically enhances the gasket's efficiency, precisely centering it on the flange face. This crucial addition prevents potential implosion into the pipe during installation, safeguarding the sealing element against extreme temperatures and aggressive mediums. It also effectively fills the void between flanges, thereby thwarting flange erosion and significantly diminishing the risk of failure. Typically, the inner ring is crafted from the same robust alloy as the winding itself, adhering to the rigorous specifications of the German DIN 2699 standard, which mandates inner rings in all spiral wound gaskets. For gaskets using PTFE filler, ASME B16.20 standards dictate the necessity of inner rings, which are also highly recommended for graphite fillers. This gasket profile is expertly designed for use in both raised and flat-faced flanges. The resilient external ring further enhances radial strength, preventing blowout, and serves as a reliable compression stop. Often made from carbon steel, these outer rings are meticulously painted or zinc-plated to resist corrosion, although they can also be crafted from specialized alloys for applications requiring higher temperature resistance and durability in more severe environments.
