Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This spiral wound gasket is equipped with an expertly engineered solid outer and inner ring, ensuring unmatched durability and reliability. Notably, the gasket features an inner ring meticulously inserted to elevate performance and precision. This ring serves multiple critical functions: it accurately centers the gasket on the flange face, prevents implosion during installation, and safeguards the sealing element against extreme conditions and media. Additionally, it fills the flange void, thereby preventing erosion and significantly reducing the risk of failure. Adhering to the DIN 2699 standard, which mandates such inner rings for all spiral wound gaskets, this configuration also aligns with the ASME B16.20 standards, particularly crucial for gaskets with PTFE and graphite fillers. This profile is adept for use in both raised and flat-faced flanges, providing additional radial strength that prevents blowouts and acts as a reliable compression stop. Commonly constructed from carbon steel (painted or zinc plated for corrosion resistance), the outer ring can also be fabricated from specialized alloys to withstand higher temperatures and harsher environments.
