Overview
This spiral wound gasket is engineered for high-pressure sealing in flange connections within demanding industrial piping systems. It is constructed to the international GB/T4622.2-2003 standard, ensuring dimensional consistency and performance reliability. The gasket is designed for a nominal pressure rating of PN16, making it suitable for a wide range of process applications involving elevated temperatures and pressures. Its robust construction provides a dependable seal that compensates for minor flange irregularities and thermal cycling.
Key Features
V-shaped spiral winding of 304 stainless steel for mechanical strength and resilience Flexible graphite filler material offering excellent thermal conductivity and chemical resistance Integrated carbon steel inner and outer retaining rings for enhanced installation stability Retaining rings prevent over-compression and assist in proper bolt load distribution Wound construction allows for superior sealing under variable load conditions Suitable for high-temperature service due to the properties of graphite and stainless steel
