Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Designed with precision and fortified with a robust solid outer and inner ring, this spiral wound gasket is engineered to meet the highest standards of industrial durability and reliability. To amplify its performance, an inner ring is strategically inserted, expertly enhancing the gasket's ability to withstand extreme conditions. It prevents any risk of implosion into the pipe during installation and shields the sealing element from harsh temperatures and aggressive mediums. This augmentation fills the gap between flanges, thus safeguarding against erosion and significantly minimizing failure risks. The inner ring, crafted from the same premium alloy as the winding, adheres to the stringent DIN 2699 standards. For gaskets equipped with PTFE filler, this feature is mandatory per ASME B16.20 standards and is highly recommended for those with graphite fillers. This advanced gasket design is ideal for both raised and flat faced flanges, incorporating an external guide ring that precisely centers the gasket on the flange face. This ring is not just a guide but also reinforces the gasket with additional radial strength to avert blowouts, acting as a reliable compression stop. Typically fashioned from carbon steel—with optional painting or zinc plating to combat corrosion—it can also be constructed from specialized alloys for applications demanding higher temperatures and more severe environmental conditions.
