Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
The Spiral Wound Gasket offered by Ningbo Dongheng Sealing Co., Ltd. is engineered with precision to deliver superior sealing performance. Equipped with a solid outer and inner ring, it features an expertly inserted inner ring to enhance its overall efficacy. This inner ring ensures the gasket remains steady and intact, protecting it from potential implosion into the pipe during installation. It serves as a robust barrier against extreme temperatures and harsh mediums, effectively filling the void between flanges to prevent erosion and minimize failure risks. Consistent with the DIN 2699 standard, which mandates inner rings for all spiral wound gaskets, our product is a testament to quality and reliability. Inner rings, crafted from the same alloy as the winding, are crucial, especially for gaskets with PTFE and graphite fillers as per ASME B16.20 standards. Ideal for both raised and flat faced flanges, the outer external guide ring provides crucial radial strength, thwarting blowouts and acting as a compression stop. Typically constructed from carbon steel, either painted or zinc plated to resist corrosion, the outer ring can also be alloyed for high-temperature and demanding applications.
