Highlighting Features:

This expertly crafted spiral wound gasket features a robust outer and inner ring designed for superior performance. The inclusion of an inner ring not only enhances gasket functionality but also ensures precise alignment on the flange face thanks to an external guide ring. Essential in preventing the gasket from imploding during installation, the inner ring safeguards against extreme temperature fluctuations and harsh mediums, thus preserving the integrity of your flanges by occupying voids and preventing erosion. It significantly minimizes the risk of failure and is typically constructed from the same alloy as the winding. Adhering to the DIN 2699 German standard, inner rings are mandatory for all spiral wound gaskets, particularly those with PTFE filler, as stipulated by ASME B16.20 standards, and are vital for graphite fillers. This design is ideally suited for both raised and flat-faced flanges. The external ring, often manufactured from carbon steel with a corrosion-resistant finish, adds radial strength to prevent gasket blowout and functions as a compression limiter. For applications demanding higher temperature resilience and handling severe mediums, outer rings can be crafted from specialized alloys.
