Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This remarkable spiral wound gasket is engineered with a robust outer and inner ring. An additional inner ring has been integrated to significantly boost the gasket's performance. The external guide ring ensures precise centering on the flange face. This inner ring is crucial; it prevents the gasket from collapsing into the pipe during setup, safeguards the sealing element against harsh temperatures and substances, and fills the gap between flanges to avert erosion, vastly minimizing the risk of failure. Typically fabricated from the same alloy as the winding, the inner ring complies with the rigorous DIN 2699 standard (German), which mandates inner rings for all spiral wound gaskets. According to ASME B16.20 specifications, inner rings are essential for PTFE fillers and highly advisable for graphite fillers. This sophisticated profile is optimal for both raised and flat-faced flanges. The external ring lends additional radial strength to counter gasket blowouts and acts as a compression stop. Often constructed from painted or zinc-plated carbon steel to prevent corrosion, it may also be crafted from alloys for elevated temperatures and demanding applications.
