Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Immerse yourself in the advanced engineering of our spiral wound gasket, designed meticulously to deliver unparalleled performance. Featuring a robust solid outer and inner ring, this gasket is enhanced by an expertly inserted inner ring that significantly boosts its overall efficacy. The inner ring serves multiple purposes: it fortifies the gasket against potential implosions into the pipe during installation, shields the sealing element from extreme temperatures and aggressive media, and fills the void between flanges to safeguard them against erosion, thereby mitigating the risk of gasket failure. Constructed typically from the same high-grade alloy as the winding, the inner ring is a critical feature specified by the DIN 2699 standard (German) for all spiral wound gaskets. Moreover, inner rings are mandated for gaskets with PTFE fillers per ASME B16.20 standards and are deemed crucial for graphite fillers. This sophisticated profile is ideally suited for raised and flat-faced flanges. Additionally, the strategically designed external guide ring plays an essential role by providing added radial strength, preventing gasket blowout, and acting as a reliable compression stop. Crafted often from carbon steel with protective paint or zinc plating to ward off corrosion, the outer ring can also be fabricated from specialized alloys for applications involving elevated temperatures and harsh environments.
