Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Exemplifying precision and reliability, this spiral wound gasket boasts a robust construction with solid outer and inner rings. Enhanced with an inserted inner ring, this design upgrade significantly amplifies gasket performance, ensuring precise centering on flange faces with an external guide ring. The inner ring's pivotal role is to prevent potential implosion into pipes during installation, safeguard the sealing element from extreme temperatures and aggressive mediums, and fill voids between flanges, thereby preventing erosion and reducing failure risks. Typically crafted from the same resilient alloy as the winding, the inner ring complies with the German DIN 2699 standard which mandates its inclusion in all spiral wound gaskets. Additionally, ASME B16.20 standards necessitate inner rings for gaskets with PTFE filler, emphasizing its importance for graphite fillers as well. This versatile profile is ideally suited for raised and flat-faced flanges. Meanwhile, the external ring lends superior radial strength, effectively preventing blowout and functioning as a compression stop. Crafted often from carbon steel, either painted or zinc-plated for corrosion resistance, the outer ring is also available in various alloys to withstand higher temperatures and more challenging mediums.
