Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Experience the pinnacle of sealing technology with our Spiral Wound Gasket, boasting a robust construction featuring solid outer and inner rings. To further amplify its performance, an expertly engineered inner ring has been integrated, enhancing its efficiency and reliability. This crucial inner component not only stabilizes the gasket during installation by preventing implosion into the pipe but also shields the sealing element from extreme conditions and corrosive mediums. It plays a vital role in filling the void between flanges, thereby safeguarding against flange erosion, while also curtailing the risk of potential failures. Typically crafted from the same high-quality alloy as the winding, the inner ring adheres to the stringent specifications of the German DIN 2699 standard, mandating their inclusion in all spiral wound gaskets. Compliant with ASME B16.20 standards, inner rings are indispensable for PTFE fillers and highly recommended for graphite fillers. Our design is ideally suited for both raised and flat-faced flanges. The external ring offers unparalleled radial strength, acting as a bulwark against gasket blowout and serving as a precise compression stop. Often composed of durable carbon steel, finished with paint or zinc plating to resist corrosion, our external rings can also be fashioned from alloys to endure higher temperatures and more challenging mediums, ensuring unmatched performance and longevity.
