Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing the exceptional James Walker Spiral Gasket—a marvel of engineering designed to meet the highest standards in sealing technology. This spiral wound gasket boasts both a robust outer and an innovative inner ring, strategically inserted to elevate gasket performance to the next level. The inner ring serves as a crucial guardian, preventing any risk of the gasket potentially imploding into the pipe during installation. It acts as a shield for the sealing element, standing firm against extreme temperatures and demanding mediums, while elegantly filling the void between flanges to avert any erosion. This protective feature also significantly reduces the chance of gasket failure, ensuring maximum durability and reliability. Typically crafted from the same durable alloy as the winding, the inner ring aligns with the German DIN 2699 standard, which specifies its inclusion in all spiral wound gaskets. Notably, gaskets with PTFE filler demand inner rings as per the stringent ASME B16.20 standards, and they are highly recommended for those with graphite fillers. This ingenious profile is specially designed for raised and flat-faced flanges, providing unparalleled performance. Complementing the inner design, the external guide ring adds an extra layer of radial strength, serving as a vital compression stop to prevent gasket blowout. Often constructed from carbon steel, painted or zinc plated for corrosion resistance, the outer ring can also be crafted from alloys for handling higher temperatures and more severe medium applications. Together, these features make the James Walker Spiral Gasket an indispensable choice for those seeking excellence and reliability in their sealing solutions.
