Product Description

SPIRAL WOUND GASKET

Product Description

 

Product Type: XINSEN-SD
Features:
Experience the unparalleled performance of our 4.5" 300# spiral wound gasket with semi-metallic construction, expertly incorporating Inconel winding for superior durability. This innovative gasket features a robust solid outer and inner ring design, enhanced by a precisely inserted inner ring that significantly boosts performance. The cleverly designed external guide ring ensures perfect alignment on the flange face. The inner ring is engineered to deliver exceptional protection against extreme temperatures and aggressive mediums, while preventing potential implosions during installation. Crafted from the same alloy as the winding, it effectively fills the void between flanges, curbing erosion and minimizing failure risks. Adhering to the rigorous DIN 2699 standard, inner rings are mandatory for all spiral wound gaskets, while ASME B16.20 standards deem them essential for gaskets with PTFE filler and crucial for graphite fillers. This premium profile is ideally suited for raised and flat-faced flanges, providing extraordinary radial strength to withstand even the most demanding environments. The outer ring, typically constructed from corrosion-resistant carbon steel, can be upgraded to high-performance alloys for exceptional resilience in high-temperature and severe medium conditions.
