Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing our innovative spiral wound gasket, meticulously engineered with a robust outer and inner ring to optimize gasket performance. Enhanced with a strategically inserted inner ring, this design offers superior protection against potential implosion during installation and safeguards the sealing element from extreme temperatures and diverse mediums. The inner ring effectively fills the void between flanges, minimizing erosion and diminishing the risk of failure. Crafted from the same high-quality alloy as the winding, this feature adheres to the DIN 2699 German standard, which mandates inner rings in all spiral wound gaskets. In compliance with ASME B16.20 standards, inner rings are essential when using PTFE filler and are highly recommended for graphite fillers. This advanced profile is ideal for both raised and flat faced flanges, while the external guide ring provides additional radial strength to prevent blowout and acts as a crucial compression stop. Frequently composed of carbon steel with corrosion-resistant coatings, outer rings can also be crafted from special alloys for high-temperature and more challenging applications.
