Overview
This industrial-grade spiral wound gasket is engineered for creating reliable, high-integrity seals in high-pressure and high-temperature flange connections. Designed for a nominal pipe size of DN400 (approximately 16 inches), it is constructed with a C-shaped metal winding core and a flexible graphite filler, all contained within an outer metal ring. This configuration ensures a robust seal that accommodates flange rotation and surface irregularities. The gasket is manufactured to conform with the HG/T20610-2009 standard and is rated for PN16 pressure classes, making it a critical component for maintaining system safety and preventing leaks in demanding process environments.
Key Features
C-shaped winding profile for enhanced sealing performance and resilience Constructed with 316L stainless steel inner and outer rings for superior corrosion resistance Flexible graphite filler provides excellent thermal conductivity and seal conformity Includes an outer containment ring to prevent gasket blow-out and over-compression Rated for PN16 pressure class, suitable for operating pressures up to approximately 232 PSI Manufactured to meet HG/T20610-2009 industry specifications for dimensional accuracy and material quality
