Overview
This industrial-grade spiral wound gasket is engineered for high-performance sealing in critical piping and vessel flanges. Manufactured in strict compliance with the HG/T 20610-2009 standard, it is designed for nominal pipe size DN200 (approximately 8 inches) and a pressure rating of PN16. The gasket's construction utilizes 316L stainless steel for superior corrosion resistance, combined with a fluoropolymer filler, creating a resilient and durable seal capable of withstanding demanding process conditions, including variable pressures, temperatures, and a broad spectrum of chemical media.
Key Features
Manufactured to HG/T 20610-2009 industry standard for dimensional consistency and performance. Designed for DN200 (8-inch) flanges with a PN16 pressure class rating. Core constructed with 316L stainless steel windings for excellent structural integrity and corrosion resistance. Fluoropolymer filler provides chemical inertness and enhances sealing performance. Reinforcing inner and outer rings made from 316L stainless steel for increased stability and prevention of gasket blow-out. Suitable for both indoor and outdoor installation in industrial environments.
