Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Experience the robustness and high performance of our spiral wound gasket, meticulously engineered with a solid outer and inner ring. The integration of an inner ring elevates the gasket's performance, ensuring it remains impeccably seated on the flange face thanks to an external guide ring. This crucial inner ring addition prevents potential implosion during installation, shields the sealing element from severe temperatures and aggressive mediums, and seamlessly fills the void between flanges, thereby preventing flange erosion and minimizing failure risk. Typically, the inner ring matches the alloy of the winding, adhering to the DIN 2699 standard which mandates inner rings in all spiral wound gaskets. In compliance with ASME B16.20 standards, PTFE filler gaskets require these rings, which are also vital for graphite fillers. Designed for both raised and flat-faced flanges, the external ring imparts significant radial strength to avert blowouts, while acting as a compression stop. Commonly constructed from carbon steel—either painted or zinc-plated to combat corrosion—it can also be crafted from specialized alloys for enduring higher temperatures and harsher conditions.
