SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
Engineered for excellence, this spiral wound gasket features robust solid outer and inner rings, with an additional inner ring meticulously inserted to significantly boost gasket performance. The external guide ring assures precise centering on the flange face. The purpose of the inner ring is to avert any possibility of implosion into the pipe during installation, shield the sealing element from extreme temperatures and mediums, fill any voids between flanges to prevent erosion, and minimize failure risk. Typically, the inner ring matches the winding alloy, adhering to the DIN 2699 standard which mandates inner rings in all spiral wound gaskets. According to ASME B16.20 standards, an inner ring is essential for PTFE fillers and is highly recommended for graphite fillers. This robust profile is perfectly suited for both raised and flat-faced flanges. The external ring enhances radial strength to avert gasket blowout and functions as a compression limiter. Often crafted from carbon steel—either painted or zinc-plated to resist corrosion—it can also be constructed from high-temperature alloys for more demanding applications.
