Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover the exceptional performance of our spiral wound gasket, expertly engineered with a robust solid outer and inner ring. This innovative design includes an inner ring for heightened performance, ensuring precise gasket placement on the flange face thanks to an external guide ring. The inner ring plays a crucial role in maintaining integrity by preventing implosion into pipes during installation, safeguarding the sealing element against extreme temperatures and harsh media. It also fills the gap between flanges to avert erosion, minimizing the risk of failure. Typically crafted from the same alloy as the winding, the inner ring adheres to the DIN 2699 German standard, which mandates its inclusion in all spiral wound gaskets. For gaskets with PTFE filler, the ASME B16.20 standards necessitate an inner ring, deeming it essential for graphite fillers as well. This profile excels in both raised and flat-faced flanges. The outer ring, providing extra radial strength to avert blowouts and acting as a compression stop, is commonly made from carbon steel, either painted or zinc-plated to withstand corrosion, and can also be constructed from high-temperature alloys for more challenging media.
