Overview
This industrial-grade spiral wound gasket is engineered for high-integrity sealing in demanding pipeline and pressure vessel applications. It is constructed with a 304 stainless steel outer wind and a flexible graphite filler, creating a resilient seal capable of accommodating flange irregularities and thermal cycling. Manufactured to stringent HG standards, this gasket is designed for nominal pipe sizes of 12 inches (DN300) and is rated for a comprehensive range of pressure classes, making it a versatile and reliable component for critical fluid handling systems.
Key Features
Robust 304 stainless steel inner and outer rings for structural stability and alignment Flexible graphite filler provides superior conformability and thermal resistance Engineered for pressure classes from PN16 through PN160 Spiral wound design offers excellent spring-back and recovery under load Suitable for a wide range of industrial media and operating temperatures
