Product Description

SPIRAL WOUND GASKET

Product Description

 

Product Type: XINSEN-SD
Features:
This superior spiral wound gasket boasts a robust construction with both solid outer and inner rings. The inner ring is meticulously incorporated to enhance the gasket's performance by preventing it from collapsing into the pipe during installation. It also safeguards the sealing element against extreme temperatures and harsh mediums, fills the void between flanges to avert flange erosion, and significantly reduces the risk of failure. Generally, the inner ring is crafted from the same alloy as the winding, adhering to the DIN 2699 German standard, which mandates inner rings in all spiral wound gaskets. According to ASME B16.20 standards, inner rings are essential for gaskets with PTFE filler and are highly recommended for graphite fillers. This configuration is typically employed in raised and flat-faced flanges. Additionally, the external guide ring provides remarkable radial strength to prevent gasket blowout and acts as a crucial compression stop. Frequently, the outer ring is made of carbon steel, either painted or zinc-plated to prevent corrosion, but can be manufactured from alloys for applications requiring higher temperatures and more severe medium resistance.
