Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Experience superior sealing with our Semi-Metal Gasket featuring a robust spiral wound design! This exceptional gasket is equipped with a solid outer and inner ring, while also incorporating an inner ring that amplifies gasket performance to new heights. Our innovative design includes an external guide ring that precisely centers the gasket on the flange face, ensuring seamless installation. The inner ring is a crucial addition, guarding against the implosion of the gasket into the pipe during installation, safeguarding the sealing element from extreme temperatures, and resisting harsh mediums. It also adeptly fills the void between flanges, thwarting flange erosion and greatly diminishing the potential for failure. Crafted typically from the same alloy as the winding, this inner ring meets the DIN 2699 German standard requirements for all spiral wound gaskets. When paired with a PTFE filler, adherence to the ASME B16.20 standards is achieved, making it indispensable for gaskets with graphite fillers. This versatile profile excels in both raised and flat-faced flanges. The external ring is ingeniously designed to bolster radial strength, preventing gasket blowout, and serves as an effective compression stop. Often manufactured from corrosion-resistant carbon steel, which can be painted or zinc-plated, the outer ring is adaptable to meet higher temperature and more intense medium applications, offering a formidable solution for all your sealing needs.
