Overview
This D-type spiral wound gasket is engineered for high-pressure, high-integrity sealing in critical industrial flange connections. It is constructed to the HG/T 20631-2009 standard, ensuring dimensional compliance and performance for demanding piping systems. The gasket is designed to create a reliable, leak-tight seal in applications involving aggressive media, elevated pressures, and variable temperatures.
Key Features
Robust D-type design with integral inner and outer stainless steel rings Winding core filled with chemically inert PTFE (polytetrafluoroethylene) Provides excellent sealing for pressures up to 600LB class
Superior chemical resistance against a wide range of corrosive fluids
The metal winding and rings offer resilience and recovery under bolt load Prevents gasket blow-out and minimizes flange rotation
Suitable for a broad operational temperature range
