Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing our advanced spiral wound gasket equipped with a robust solid outer and inner ring for enhanced durability. An expertly inserted inner ring elevates gasket performance, while an external guide ring ensures precise centering on the flange face for optimal efficiency. This inner ring is ingeniously designed to prevent potential implosion into the pipe during installation, offering protection against extreme temperatures and harsh mediums. It fills the void between flanges to avert erosion and significantly diminishes the likelihood of gasket failure. Typically crafted from the same alloy as the winding, the inner ring's importance is underscored by its requirement in gaskets with PTFE fillers under ASME B16.20 standards, and its essential role with graphite fillers. Perfectly suited for both raised and flat-faced flanges, the external ring adds vital radial strength to prevent blowout and serves as a reliable compression stop. Often constructed from carbon steel to resist corrosion, it can also be made from high-performance alloys to withstand elevated temperatures and severe conditions.
