Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This remarkable spiral wound gasket boasts a solid outer and inner ring construction. Notably, an inner ring has been integrated to significantly boost gasket performance, accompanied by an external guide ring that ensures precise centering on the flange face. The meticulously designed inner ring is crucial in preventing the gasket from collapsing into the pipe during installation, while safeguarding the sealing element from harsh temperatures and challenging mediums. Additionally, it fills the gap between the flanges to thwart flange erosion and minimize potential failures. Typically crafted from the same alloy as the winding, the inner ring adheres to the German DIN 2699 standard, which mandates its inclusion in all spiral wound gaskets. This is especially vital for gaskets with PTFE fillers, as per ASME B16.20 standards, and is highly recommended for those with graphite fillers. This design is ideally suited for raised and flat-faced flanges. Meanwhile, the external ring provides enhanced radial strength, preventing gasket blowout and serving as a compression limiter. It is generally crafted from carbon steel, either painted or zinc-plated for corrosion resistance, but can also be constructed from alloys for demanding high-temperature and severe medium applications.
