Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This cutting-edge spiral wound gasket comes equipped with a robust outer and inner ring, meticulously designed to enhance performance. The inclusion of an inner ring is a strategic feature, preventing gasket implosion during installation. This ring safeguards the sealing element against extreme temperatures and aggressive mediums, while adeptly filling the gap between flanges to guard against erosion. Furthermore, it significantly mitigates the risk of failure. Typically crafted from the same high-quality alloy as the winding, the inner ring adheres to the DIN 2699 standard as dictated by German specifications. It is mandatory for gaskets with PTFE filler under ASME B16.20 standards and is highly recommended for those with graphite fillers. Ideal for both raised and flat-faced flanges, the external guide ring ensures perfect flange face alignment, providing remarkable radial strength to avert blowouts. This ring also acts as a vital compression stop. The outer ring, often constructed from carbon steel (either painted or zinc-plated for corrosion resistance), can be crafted from specialized alloys to withstand higher temperatures and more demanding applications.
