Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing the pinnacle of sealing technology: a remarkable spiral wound gasket meticulously designed to feature a robust outer ring complemented by an ingenious Monel inner ring. This pivotal component revolutionizes the gasket's functionality and steadfastness. The inner ring's strategic positioning ensures impeccable alignment on the flange face, effectively eliminating any risk of misalignment that could precipitate failures. This structural enhancement not only reinforces the gasket against deformation during installation but also provides exceptional defense against extreme thermal conditions and corrosive substances, safeguarding its structural integrity. By adeptly bridging the gap between flanges, it significantly reduces erosion threats and markedly diminishes the likelihood of gasket failure. Expertly crafted from the same premium alloy as the winding, the inner ring complies with the stringent DIN 2699 standard, which stipulates its necessity in all spiral wound gaskets. Its importance is particularly emphasized in gaskets featuring PTFE filler, as acknowledged by the ASME B16.20 standards, which mandate inner rings to uphold the effectiveness of graphite fillers. This versatile gasket design is optimally engineered for both raised and flat-faced flanges. The external guide ring not only enhances radial strength to avert blowout but also serves as a critical compression stop, amplifying the gasket's durability. Typically made from painted or zinc-plated carbon steel for corrosion resistance, the outer ring can also be fabricated from specialized alloys to endure higher temperatures and more challenging environments.
