SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This sophisticated spiral wound gasket is engineered with precision, boasting a robust solid outer and inner ring for enhanced durability and reliability. An expertly inserted inner ring elevates gasket performance, ensuring impeccable centering on the flange face with an external guide ring. The inner ring is a vital component, safeguarding against implosion into the pipe during installation, shielding the sealing element from harsh temperatures and corrosive mediums. It fills the flange void to prevent erosion, significantly reducing failure risks. Typically crafted from the same alloy as the winding, the inner ring adheres to the DIN 2699 standard (German), with ASME B16.20 standards mandating its use for gaskets with PTFE filler and highly recommended for graphite fillers. This versatile profile is ideal for both raised and flat-faced flanges. The external ring not only provides added radial strength to combat gasket blowout but also acts as a precise compression stop. Carbon steel, often painted or zinc-plated to resist corrosion, is a popular choice for the outer ring, although higher-temperature and severe medium applications may require alloy construction.
