Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This meticulously engineered spiral wound gasket is designed with both solid outer and inner rings to ensure superior performance and reliability. The inner ring, strategically inserted, significantly enhances gasket durability by preventing any implosion into the pipe during installation. It offers robust protection against extreme temperatures and aggressive mediums, effectively filling voids between flanges to avert erosion and minimize failure risks. Adhering to the DIN 2699 German standard, and the ASME B16.20 requirements for PTFE fillers, inner rings are crafted from the same premium alloy as the gasket winding, crucial for both PTFE and graphite fillers. Ideal for raised and flat-faced flanges, the external guide ring precisely centers the gasket on the flange face, while its carbon steel (painted or zinc plated) composition, or optional alloy for high-temperature applications, provides additional radial strength to avert blowouts and acts as a reliable compression stop.
