Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing the remarkable spiral wound gasket, meticulously crafted with a robust solid outer and inner ring. For enhanced performance, an inner ring has been strategically incorporated to elevate gasket efficiency. The accompanying external guide ring ensures precise centering on the flange face. This innovative inner ring serves multiple vital functions: it prevents the gasket from imploding into the pipe during installation, shields the sealing element from extreme conditions, fills the space between flanges to avert erosion, and minimizes failure risks. Remarkably, the inner ring often matches the alloy of the winding, while adhering to stringent standards like DIN 2699 and ASME B16.20. Notably, inner rings are essential for gaskets with PTFE fillers and highly recommended for graphite varieties. This sophisticated profile is ideally suited for both raised and flat-faced flanges. Additionally, the sturdy external ring augments radial strength, acting as a safeguard against blowouts and serving as a compression stop. Crafted with meticulous precision, the outer ring is typically made of carbon steel, either painted or zinc-plated to stave off corrosion. However, for high-temperature or severe applications, alloy options are available, ensuring unmatched resilience and performance.
