Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Experience the exceptional engineering of our Spiral Wound Gasket, designed for robustness and reliability. This gasket features a solid outer and inner ring to ensure superior sealing performance. The incorporated inner ring is a crucial enhancement, meticulously designed to prevent the gasket from imploding into the pipe during installation. It protects against extreme temperatures and harsh mediums, effectively filling voids between flanges to prevent flange erosion and reduce failure risks. The inner ring is typically crafted from the same high-quality alloy as the winding, adhering to the rigorous DIN 2699 standard. For gaskets with PTFE filler, inner rings are mandated by ASME B16.20 standards, and hold significant importance for those with graphite fillers. This gasket profile is ideally suited for applications with raised and flat-faced flanges. The external guide ring introduces additional radial strength to avert blowouts, acting as a dependable compression stop. Often manufactured from durable carbon steel, which is either painted or zinc-plated to resist corrosion, the outer ring can also be tailored with alloy materials for operations involving higher temperatures and more demanding conditions.
