Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing our meticulously engineered spiral wound gasket, designed to provide unparalleled sealing capabilities. It features a robust outer and inner ring structure, ensuring optimal performance. The expertly integrated inner ring not only enhances the gasket's durability but also prevents potential implosion during installation. It serves as a safeguard for the sealing element against extreme environments and media, effectively filling flange gaps to prevent erosion and mitigate failure risks. Crafted from materials matching the winding alloy, this inner ring adheres to DIN 2699 standards and aligns with ASME B16.20 requirements for PTFE fillers, with significant importance for graphite fillers. Perfect for both raised and flat face flanges, the external guide ring adds radial strength and functions as a precision centering tool, preventing blowouts and serving as a compression limiter. Typically constructed from carbon steel with protective coatings, the outer ring can also be customized with alloys to withstand higher temperatures and more demanding applications.
