Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This spiral wound gasket features a robust design with both solid outer and inner rings. The inclusion of an inner ring significantly enhances its performance, ensuring the gasket remains intact during installation and operation. It effectively centers the gasket on the flange face and prevents any potential implosion into the pipe. Additionally, it offers protection against extreme temperatures and media, fills the void between flanges to avert flange erosion, and minimizes failure risks. The inner ring typically matches the winding material in composition and meets the DIN 2699 specifications for all spiral wound gaskets, with PTFE fillers requiring inner rings as per ASME B16.20 standards. They are also crucial for graphite fillers. This design is ideal for both raised and flat-faced flanges. The external guide ring adds radial strength, preventing blowouts and serving as a compression stop. Usually crafted from carbon steel for durability, it may also be made from alloys for high-temperature or severe conditions, offering painted or zinc-plated options to counter corrosion.
