Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing the meticulously engineered ASME B16.20 Spiral Gasket with Mica Filler and SS316 Winding, a marvel of precision and durability designed by Ningbo Dongheng Sealing Co., Ltd. This advanced gasket is fortified with solid outer and inner rings, enhanced by an additional inner ring for superior performance. It is engineered to securely center on the flange face, offering unmatched stability. The inner ring, crafted to the highest standards, plays a crucial role in preventing implosions during installation, safeguarding the sealing elements from extreme conditions, and effectively reducing flange erosion and risk of failure. Adhering to the DIN 2699 standard, this gasket incorporates inner rings as mandated for PTFE fillers per ASME B16.20 standards, proving its essential value for graphite fillers too. This configuration is perfect for both raised and flat-faced flanges. The external guide ring not only provides additional radial strength to avert blowouts but also serves as a compression stop, ensuring peak performance. Typically constructed from carbon steel, often painted or zinc plated for corrosion resistance, the outer ring can also be customized with high-grade alloys for applications demanding higher thermal tolerance and medium severity.
