Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This exceptional spiral wound gasket is meticulously engineered with a robust outer and inner ring. The inclusion of an internal ring is pivotal, enhancing the overall gasket performance. This feature ensures precise centering of the gasket on the flange face with the use of an external guide ring. The inner ring is crucial, safeguarding against the implosion of the gasket into the pipe during installation, and offering protection against extreme temperatures and aggressive mediums. It effectively fills the void between flanges, preventing flange erosion and minimizing failure risks. Typically crafted from the same high-quality alloy as the winding, the inner ring's importance is underscored by the DIN 2699 standard and ASME B16.20 standards, which mandate its use in gaskets with PTFE filler and highlight its significance for graphite fillers. Designed for raised and flat-faced flanges, the external ring provides substantial radial strength, preventing blowouts and acting as a compression stop. Often made from carbon steel, with options for painting or zinc plating to combat corrosion, the outer ring can also be crafted from premium alloys for more extreme temperature and demanding medium applications.
