Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing the robust and reliable Spiral Wound Gasket from Ningbo Dongheng Sealing Co., Ltd. This exceptional gasket is meticulously crafted with a solid outer and inner ring, ensuring unparalleled performance. The addition of an inner ring elevates the gasket's capability by preventing implosion into the pipe during installation and safeguarding the sealing element from extreme conditions and harsh mediums. This crucial component fills the void between flanges, curbing erosion and significantly reducing the risk of failure. Crafted from the same high-quality alloy as the winding, the inner ring adheres to the prestigious DIN 2699 standard, which mandates its inclusion in all spiral wound gaskets. According to ASME B16.20 standards, an inner ring is essential for gaskets with PTFE filler and is highly recommended for those with graphite fillers. This sophisticated profile is ideally suited for both raised and flat-faced flanges. Meanwhile, the external guide ring provides substantial radial strength to avert gasket blowout, also serving as a reliable compression stop. Typically made of robust carbon steel, painted or zinc-plated to resist corrosion, the outer ring can also be crafted from alloys for applications involving higher temperatures or more severe mediums. Experience the unmatched reliability and superior technology of this Spiral Wound Gasket, designed for excellence in demanding environments.
