Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Discover the exceptional capabilities of this spiral wound gasket, meticulously designed with a solid outer and inner ring for unparalleled performance. The integration of an inner ring is a testament to its superior functionality, enhancing gasket performance by ensuring precise centering on the flange face. This crucial component is inserted to prevent the risk of implosion during installation, safeguard the sealing element from extreme conditions, and fill the voids between flanges, thereby protecting against erosion and reducing failure risks. Made from the same robust alloy as the winding, the inner ring adheres to the stringent DIN 2699 standards, a German specification for spiral wound gaskets. According to ASME B16.20 standards, inner rings are essential for gaskets with PTFE filler and highly recommended for graphite fillers, ensuring reliability in raised and flat-faced flanges. The external ring, crafted for additional radial strength, prevents blowouts and functions as a compression stop, often made from carbon steel that's either painted or zinc plated for corrosion resistance. For applications demanding higher temperature endurance and severe medium resistance, the outer ring can be fashioned from specialized alloys, making this gasket a versatile choice across various industrial applications.
