Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing an exceptional spiral wound gasket from Ningbo Dongheng Sealing Co., Ltd., crafted to elevate your sealing solutions. This sophisticated gasket boasts a robust solid outer and inner ring design, with an additional inner ring inserted to optimize performance and ensure precision. The external guide ring meticulously centers the gasket on the flange face, providing seamless installation. The inner ring, crafted from the same alloy as the winding, is ingeniously added to prevent implosion into the pipe during installation. It safeguards the sealing element from extreme temperatures and harsh mediums, fills voids between flanges to thwart erosion, and significantly reduces failure risks. In accordance with the esteemed DIN 2699 standard, inner rings are a staple in all spiral wound gaskets. As per ASME B16.20 standards, inner rings are essential for gaskets with PTFE fillers and are highly recommended for graphite fillers. This cutting-edge profile is designed for both raised and flat-faced flanges, ensuring versatility in application. The external ring, providing unparalleled radial strength to avert blowouts, also doubles as a compression stop. Typically constructed from carbon steel, which is either painted or zinc plated to resist corrosion, the outer ring can also be manufactured from alloys, catering to high-temperature and demanding medium applications.
