Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This spiral wound gasket is engineered with precision, featuring a robust solid outer and inner ring design. Notably, an inner ring is incorporated to significantly enhance the gasket's performance. This ingenious addition not only prevents the gasket from imploding into the pipe during installation but also acts as a guardian against extreme temperatures and aggressive mediums. It effectively fills the void between flanges, safeguarding against flange erosion and minimizing the risk of failure. Constructed from the same alloy as the winding, the inner ring is a testament to durability and resilience. As per the German DIN 2699 standard, inner rings are essential in all spiral wound gaskets, and as per ASME B16.20 standards, they are mandatory for gaskets with PTFE filler and highly recommended for those with graphite fillers. This profile is optimally suited for raised and flat-faced flanges. Furthermore, the external guide ring provides additional radial strength, guarding against gasket blowout and serving as a reliable compression stop. Typically crafted from carbon steel with a protective coating to resist corrosion, the outer ring can also be made from specialized alloys for applications involving higher temperatures and aggressive mediums.
