Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing our cutting-edge spiral wound gasket, expertly designed with a robust solid outer and inner ring. The inclusion of an inner ring is pivotal, boosting the gasket's performance by ensuring accurate centering on the flange face and safeguarding against implosion into the pipe during installation. It shields the sealing element from harsh temperatures and mediums, fills the void between flanges to mitigate flange erosion, and significantly lowers the risk of failure. Crafted typically from the same alloy as the winding, the inner ring is indispensable—especially in adherence to the DIN 2699 standard (German) and ASME B16.20 standards for gaskets with PTFE and graphite fillers. Predominantly used in both raised and flat faced flanges, this profile is enhanced by the external guide ring, adding radial strength to thwart potential blowout and serving as a compression limiter. The outer ring, often manufactured from carbon steel with a protective paint or zinc coating to resist corrosion, can also be alloy-based for resilience in high-temperature and severe applications.
