SPIRAL WOUND GASKET - An Exquisite Gasket Solution

Product Description

DESCRIPTION: - Where Innovation Meets Precision

Product Type: - Defining Quality and DurabilityXINSEN-SD - A Benchmark of Reliability

Features: - Elevate Your Expectations

This spiral wound gasket boasts a robust outer and inner ring, designed for optimum performance. An inserted inner ring enhances the gasket's functionality, while an external guide ring ensures precise centering on the flange face. The inner ring safeguards the gasket from implosion into the pipe during installation, shields the sealing element from harsh temperatures and media, fills voids between flanges to prevent flange erosion, and minimizes failure risk. Crafted typically from the same alloy as the winding, the inner ring meets DIN 2699 standards (German) and is essential for PTFE fillers per ASME B16.20 standards, playing a vital role in graphite fillers. Designed for raised and flat-faced flanges, the external ring fortifies the gasket against blowout, acting as a compression stop. Often made from carbon steel, painted or zinc-plated to combat corrosion, the outer ring can also be fabricated from alloys for higher temperature and more severe medium applications.
