Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Experience the pinnacle of sealing technology with our spiral wound gasket, which incorporates a robust solid outer and inner ring to maximize performance. The inner ring is skillfully inserted to enhance the gasket's capability, ensuring precise centering on the flange face with its external guide ring. This inner ring serves multiple purposes: it prevents gasket implosion during installation, shields the sealing element against extreme temperatures and harsh mediums, fills flange voids to avert erosion, and significantly minimizes potential failures. Crafted typically from the same alloy as the winding, the inner ring aligns with the German DIN 2699 standard, which mandates its inclusion in all spiral wound gaskets. According to ASME B16.20 standards, inner rings are crucial for PTFE fillers and are considered significant for graphite fillers. This sophisticated profile is ideal for both raised and flat-faced flanges. The external ring is engineered to provide superior radial strength, acting as a compression stop to prevent blowouts. Commonly composed of carbon steel—either painted or zinc-plated for corrosion resistance—the outer ring is adaptable for use with alloys to meet higher temperature and severe medium demands.
