Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover the exceptional engineering behind our spiral wound gasket, featuring robust solid outer and inner rings. We've meticulously inserted an inner ring to significantly boost performance, ensuring optimal positioning on the flange face via an external guide ring. This inner ring serves crucial functions: it prevents the gasket from collapsing into the pipe during installation, shields the sealing element from extreme conditions, fills voids between flanges to avoid erosion, and minimizes failure risks. Constructed from the same alloy as the winding, the inner ring aligns with DIN 2699 standards and is essential for gaskets with PTFE fillers per ASME B16.20. It also plays a vital role with graphite fillers. Ideal for raised and flat-faced flanges, the external ring delivers additional radial strength to avert blowouts and acts as a compression stop. Typically crafted from corrosion-resistant carbon steel or specialized alloys for high-temperature and demanding environments, this profile is designed for superior durability and reliability.
