Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This spiral wound gasket is ingeniously designed with a robust outer and inner ring. The addition of an inner ring significantly elevates the gasket's overall performance, ensuring a precise fit on the flange face through an external guide ring. This enhancement prevents potential gasket implosion into the pipe during setup, offers protection to the sealing component against intense temperatures and various media, and fills the gap between flanges to thwart flange erosion, thereby minimizing the risk of failure. Typically, the inner ring matches the winding's alloy, adhering to the DIN 2699 standard, which mandates inner rings for all spiral wound gaskets. According to ASME B16.20 standards, inner rings are imperative for PTFE filler gaskets and are deemed critical for graphite fillers. This sophisticated profile is ideal for both raised and flat-faced flanges. The external ring delivers essential radial strength to avert gasket blowouts and serves as a compression limiter. Carbon steel, often painted or zinc-plated to resist corrosion, is commonly used for the outer ring, although other alloys can be employed for extreme temperatures or more challenging applications.
