Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

The ASME B16.20 Sealing Gasket with 316 Inner Ring and Strong Graphite by Ningbo Dongheng Sealing Co., Ltd. is a marvel of engineering and innovation. This spiral wound gasket boasts a solid outer and inner ring, intricately designed to elevate performance. A meticulously inserted inner ring serves to greatly enhance the gasket's durability, ensuring secure installation by preventing implosion into the pipe. It also acts as a shield for the sealing element against extreme temperatures and various mediums, effectively filling the void between flanges to avert flange erosion, thus significantly reducing the risk of failure. Constructed typically from an alloy matching the winding, the inner ring is in full compliance with the stringent DIN 2699 standard, mandating it for all spiral wound gaskets, and is critical for those with PTFE and graphite fillers under ASME B16.20 standards. This versatile profile is expertly crafted for both raised and flat faced flanges. Adding to its robustness, the external guide ring provides essential radial strength to prevent blowouts and functions as a compression stop, with the outer ring commonly made from corrosion-resistant carbon steel or high-temperature alloys for severe environments, offering unmatched reliability.
