Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover the superior craftsmanship of this spiral wound gasket, thoughtfully engineered with a robust outer and inner ring configuration. To elevate its performance, an additional inner ring is adeptly inserted. This inner ring acts as a safeguard, preventing potential implosion into the pipe during installation, shielding the sealing element from extreme conditions, and effectively filling gaps between flanges to avert erosion. It is crafted to significantly diminish the risk of failure. Conventionally, the inner ring is composed of the same high-quality alloy as the winding. Compliance with the prestigious DIN 2699 standard (German) ensures precision with inner rings in all spiral wound gaskets. ASME B16.20 standards mandate inner rings for gaskets with PTFE filler, underscoring their critical importance for those with graphite fillers. Tailored for raised and flat-faced flanges, this profile offers unmatched reliability. The external guide ring is meticulously engineered to provide additional radial strength, preventing blowouts and functioning as a precise compression stop. This design is ideal for both raised and flat-faced flanged applications. Typically, the outer ring is fabricated from carbon steel and is either painted or zinc-plated to combat corrosion, or it is constructed from specialized alloys for operations in higher temperature and more demanding medium environments.
