Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing our exceptional spiral wound gasket, a marvel of engineering crafted with precision and expertise. This advanced gasket integrates a robust solid outer and inner ring, enhanced with an inserted inner ring for superior performance. This innovative design not only ensures accurate centering on the flange face but also fortifies the gasket against the risk of imploding into the pipe during installation. The inner ring serves as a guardian for the sealing element, shielding it from extreme temperatures and harsh mediums while filling the void between flanges to prevent erosion and significantly reducing the possibility of failure. Constructed typically from the same alloy as the winding, the inner ring adheres to the DIN 2699 standard, mandating its inclusion in all spiral wound gaskets, and is essential for gaskets with PTFE filler as per ASME B16.20 standards, with added importance for graphite fillers. Designed for both raised and flat-faced flanges, the external guide ring offers additional radial strength, acting as a reliable compression stop to prevent gasket blowout. Often crafted from carbon steel and treated to resist corrosion, or from advanced alloys for higher temperature and more demanding applications, the outer ring ensures durability and reliability in the harshest conditions.
