Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Experience unparalleled sealing performance with our Spiral Wound Gasket, meticulously engineered to meet the highest industry standards. This exceptional gasket is equipped with both a solid outer and inner ring, with the addition of an expertly inserted inner ring that elevates its functionality. The external guide ring ensures precise centering on the flange face, offering superior installation accuracy. The inner ring serves as a safeguard against potential implosion into the pipe, protecting the seal from extreme conditions, filling flange voids to prevent erosion, and minimizing the risk of failure. Crafted to match the alloy of the winding, the inner ring adheres to the DIN 2699 German standard, and is crucial for PTFE fillers as per ASME B16.20 regulations, as well as being highly recommended for graphite fillers. Ideal for use in raised and flat-faced flanges, the external ring provides additional radial strength, preventing blowout and acting as a compression limiter. Typically composed of carbon steel, it is available in painted or zinc-plated finishes to combat corrosion, or in specialized alloys for applications demanding higher temperatures and more aggressive environments.
