Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover the unparalleled strength and precision of our High-Temperature Spiral Gasket with PTFE Filler and SS304 Winding. Engineered with a robust solid outer and inner ring, this gasket includes an inserted inner ring to amplify performance and ensure flawless functionality. The strategic addition of the inner ring plays a pivotal role in safeguarding the gasket from imploding into the pipe during installation, shielding the sealing element from extreme conditions, bridging voids to thwart flange erosion, and reducing failure potential. Crafted typically from the same durable alloy as the winding, our inner rings are meticulously designed in compliance with the esteemed DIN 2699 standard (German) and align with ASME B16.20 standards. Essential for gaskets with PTFE fillers and significantly beneficial for graphite fillers, this design thrives in both raised and flat-faced flanges. Furthermore, the external guide ring, crafted with precision, offers enhanced radial strength to avert blowouts and serves as a steadfast compression boundary. Often manufactured from corrosion-resistant carbon steel, either painted or zinc-plated, these outer rings also come in alloys tailored for elevated temperatures and more demanding applications. Experience the pinnacle of sealing technology where innovation meets reliability.
