Product Description

SPIRAL WOUND GASKET

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing the Precision Fit Metal Spiral Wound, Semi-Metallic, Spiral Gasket, engineered to perfection for all flanges. This state-of-the-art gasket boasts a solid outer and inner ring, with an additional inner ring inserted to elevate its performance to new heights. This innovative design enhances installation safety by preventing potential gasket implosion into the pipe, shields the sealing element from extreme conditions, fills voids between flanges to avert erosion, and significantly reduces failure risks. The inner ring, crafted typically from the same alloy as the winding, is essential in meeting the DIN 2699 German standards and vital for PTFE and graphite fillers as per ASME B16.20 norms. Ideal for both raised and flat-face flanges, the external guide ring offers superior radial strength, prevents blowout, and acts as a compression barrier. Constructed from robust carbon steel, either painted or zinc-plated to combat corrosion, or from specialized alloys for high-temperature and severe conditions, this gasket is truly a versatile solution for modern industrial needs.
