Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Crafted with meticulous precision, this spiral wound gasket features a robust and solid design with both outer and inner rings. To elevate its performance, an inner ring has been thoughtfully integrated. This ring not only optimizes gasket alignment on the flange face but also significantly boosts its overall durability by acting as a safeguard against harsh temperatures and corrosive environments. It prevents the gasket from collapsing into the pipe during installation, fills flange gaps to avert erosion, and enhances reliability. Standardized by DIN 2699, inner rings are essential, especially in gaskets with PTFE fillers, as per ASME B16.20 standards, and are invaluable for graphite fillers too. Perfectly suited for raised and flat-faced flanges, the external guide ring fortifies against radial stress, thwarting gasket blowouts, and serves as a compression limiter. Often manufactured from carbon steel, either painted or zinc-plated to resist corrosion, the outer ring can also be crafted from high-grade alloys for applications demanding extreme temperature resistance and exposure to aggressive mediums.
