Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Ningbo Dongheng Sealing Co., Ltd. proudly presents the ASME B16.20 Gasket with Mica Filler and Inconel Winding. This advanced spiral wound gasket showcases a solid outer and inner ring, with an expertly inserted inner ring to maximize performance. The external guide ring ensures impeccable flange face centering. To avert installation mishaps, the inner ring guards against potential implosions into the pipe, shields the sealing element from extreme conditions, fills any flange voids to prevent erosion, and significantly lowers the risk of failure. Crafted from the same alloy as the winding, this integral component adheres to the DIN 2699 (German) standards, mandating inner rings for all spiral wound gaskets. For PTFE fillers, the ASME B16.20 standards require an inner ring, while they are highly beneficial for graphite fillers. This sophisticated profile excels in both raised and flat-faced flange applications, with the external ring fortifying the gasket with additional radial strength to mitigate blowouts and act as a compression limiter. Typically forged from carbon steel and coated to resist corrosion, outer rings can also be crafted from robust alloys for environments demanding higher temperatures and more aggressive media.
