Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This cutting-edge spiral wound gasket boasts a sturdy outer and inner ring, ensuring unparalleled performance. An innovative inner ring has been meticulously inserted to elevate the gasket's efficiency, while the precisely engineered external guide ring guarantees accurate centering on the flange face. The inner ring offers robust protection, safeguarding against potential implosion during installation, shielding the sealing element from extreme conditions, and filling flange voids to avert erosion. Its material consistency, matching the winding's alloy, further fortifies its structure. Conforming to DIN 2699 standards, inner rings are mandatory for all spiral wound gaskets, especially those with PTFE fillers according to ASME B16.20 standards, and highly recommended for graphite fillers, enhancing reliability. This versatile profile is ideal for raised and flat-faced flanges, with the external ring providing extra radial strength to thwart blowouts and serving as a compression stop. Typically crafted from carbon steel, it may also be made from specialized alloys to withstand higher temperatures and more demanding applications. Painted or zinc-plated, the outer ring is fortified against corrosion, ready to meet the most rigorous industrial challenges.
