Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
The James Walker Gasket with Mica Filler and SS347 Winding Design is crafted with precision and excellence, featuring a robust spiral wound structure. It is designed with a solid outer ring and an inner ring to bolster its performance. The ingeniously inserted inner ring ensures the gasket maintains its integrity, preventing any potential implosion into the pipe during installation. It acts as a shield, protecting the sealing element from extreme temperatures and harsh media, while also filling gaps between flanges to avert erosion and minimize failure risks. The inner ring material typically matches the winding alloy, adhering to the DIN 2699 specification, which mandates inner rings for all spiral wound gaskets. According to ASME B16.20, inner rings are essential for gaskets with PTFE fillers and are highly recommended for graphite fillers. This particular gasket profile is ideally suited for raised and flat-faced flanges. Additionally, the external guide ring offers crucial radial strength to prevent blowout, functioning as a compression stop. Usually composed of carbon steel—either painted or zinc-plated to resist corrosion—the external ring can also be crafted from specialized alloys for more demanding temperature and media conditions.
