Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This spiral wound gasket, crafted with an external guide ring and solid outer and inner rings, features an inserted inner ring to significantly enhance its performance. The inner ring prevents the gasket from imploding into the pipe during installation, protects the sealing element from extreme temperatures and mediums, fills the void between flanges to prevent erosion, and reduces the risk of failure. Typically made from the same alloy as the winding, the inner ring meets DIN 2699 standards for all spiral wound gaskets. For gaskets with PTFE filler, it adheres to ASME B16.20 standards, and it is highly recommended for graphite fillers. This profile suits both raised and flat-faced flanges, providing additional radial strength and acting as a compression stop to prevent gasket blowout. The outer ring, often made of carbon steel with a painted or zinc-plated finish to prevent corrosion, can also be made from alloys for high-temperature and severe medium applications.
