Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing our premium Spiral Gasket with 321 Inner Ring and Durable Graphite Winding, an epitome of engineering excellence and reliability. This well-designed gasket boasts a robust outer and inner ring, with an inner ring strategically inserted to elevate the overall gasket performance. This feature not only ensures precision during installation by centering the gasket accurately on the flange face but also adds an indispensable layer of protection against extreme temperatures and mediums. The inner ring effectively mitigates the risk of the gasket collapsing into the pipe while also filling the void between flanges to prevent erosion, thus significantly minimizing the potential for failure. Fabricated typically from the same alloy as the winding, the inner ring complies with the DIN 2699 standard (German) and is essential for gaskets containing PTFE fillers as per the ASME B16.20 standards, highlighting its importance for graphite fillers. Our gasket design is adept for use in both raised and flat-faced flanges. Moreover, the external guide ring, crafted to provide formidable radial strength, acts as a reliable compression stop that prevents blowouts. The outer ring, usually made of carbon steel and treated to resist corrosion, can also be manufactured from specialized alloys for high-temperature and aggressive medium applications.
