SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This spiral wound gasket is meticulously engineered with a robust solid outer and inner ring. The inclusion of an inner ring is a strategic enhancement that significantly boosts gasket performance. It ensures precise centering on the flange face with an external guide ring, effectively preventing the gasket from imploding into the pipe during installation. The inner ring serves as a vital shield for the sealing element against extreme temperatures and harsh mediums, fills the void between flanges to avert erosion, and diminishes the risk of failure. Crafted from the same alloy as the winding, it adheres to the stringent DIN 2699 standard, mandating inner rings for all spiral wound gaskets. For gaskets with PTFE fillers, the ASME B16.20 standards necessitate an inner ring, which is equally crucial for graphite fillers. This design is ideally suited for both raised and flat-faced flanges. The external ring, made of carbon steel (painted or zinc plated for corrosion resistance), or high-performance alloys for more demanding conditions, adds extra radial strength to prevent gasket blowout and serves as a compression limiter, ensuring reliability in high-stakes applications.
