Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This state-of-the-art spiral wound gasket is crafted with sturdy outer and inner rings, featuring an additional inner ring meticulously inserted to significantly boost gasket performance. The precision-engineered external guide ring ensures seamless gasket alignment on the flange face. The inner ring plays a pivotal role in safeguarding against potential gasket implosions during installation, shielding the sealing element from extreme conditions, and filling any voids between flanges to prevent flange erosion and minimize failure risks. Typically constructed from the same robust alloy as the winding, the inner ring meets the stringent DIN 2699 standard (German) for all spiral wound gaskets. According to ASME B16.20 standards, inner rings are essential for gaskets with PTFE filler and highly recommended for those with graphite fillers. This versatile profile is ideal for raised and flat-faced flanges. The external ring not only adds extra radial strength to avert gasket blowout but also functions as a compression limiter. Often crafted from carbon steel (skillfully painted or zinc plated to resist corrosion), the outer ring can also be fabricated from alloys to withstand higher temperatures and more demanding applications, ensuring durability and reliability.
