Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Step into a world of unparalleled excellence with our ASME B16.20 Spiral Gasket, designed with an uncompromising approach to sealing perfection. This superior gasket features a robust and solid outer ring, complemented by an expertly integrated inner ring designed to elevate performance to new heights. This meticulously inserted inner ring not only ensures precise centering on the flange face but also serves crucial functions: it guards against potential gasket implosion during installation, protects the sealing element from extreme temperatures and aggressive mediums, and fills the void between flanges to prevent erosion, thereby significantly reducing the risk of gasket failure. Adhering to the stringent DIN 2699 standards, this inner ring, crafted from the same premium alloy as the winding, is essential, especially when paired with PTFE fillers in compliance with ASME B16.20 standards, and plays a vital role for graphite fillers. Ideal for both raised and flat-faced flanges, this innovative profile also boasts an external guide ring, enhancing radial strength to prevent blowout and acting as a precision compression stop. For those demanding higher temperature and more severe medium applications, the outer ring, typically constructed from carbon steel and either painted or zinc plated to resist corrosion, can be custom-made using high-performance alloys.
