Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing our top-tier spiral wound gasket, crafted for unparalleled reliability and performance. This innovative design boasts a robust outer and inner ring, with the inner ring meticulously inserted to elevate gasket performance. The external guide ring ensures precise centering on the flange face. The inner ring serves multiple vital functions: it safeguards against implosion into pipes during installation, shields the sealing element from extreme temperatures and harsh mediums, fills flange voids to avert erosion, and significantly reduces failure risk. Constructed typically from the same high-grade alloy as the winding, our gaskets align with the DIN 2699 standard, mandating inner rings in all spiral wound gaskets. Under ASME B16.20 standards, PTFE filler gaskets necessitate inner rings, while they are highly recommended for graphite fillers. Designed for both raised and flat-faced flanges, our external ring delivers superior radial strength, preventing blowouts and serving as a precise compression stop. Often fabricated from corrosion-resistant carbon steel, these rings are also available in high-temperature alloys, catering to severe applications.
