Overview
This 2.5-inch nominal size spiral wound gasket is engineered for creating robust, long-lasting seals in demanding industrial piping and vessel applications. It is constructed by spirally winding a combination of metallic and non-metallic materials, forming a resilient seal that compensates for flange irregularities and thermal cycling. The gasket is manufactured to the HG/T20610-2009 standard, ensuring dimensional consistency and performance reliability for a wide range of pressure classes.
Key Features
Constructed with a durable 304 stainless steel outer winding for corrosion resistance Features a resilient graphite filler for superior thermal and chemical compatibility Designed to handle multiple pressure classes from PN10 to PN63 Provides an effective seal for both indoor and outdoor installations The spiral wound design offers excellent recovery and sealing under variable loads
