Overview
This Type B spiral wound gasket is engineered for high-pressure, high-integrity sealing in critical industrial piping and flange connections. It is manufactured in strict compliance with the SH/T3407-2013 standard, ensuring dimensional accuracy and performance reliability for a nominal pipe size of 60 inches and a pressure class of 900 pounds. The gasket features a robust construction with a 304 stainless steel winding and a polytetrafluoroethylene (PTFE) filler, all centered and reinforced by an inner retaining ring of 304 stainless steel. This design creates a resilient, leak-tight seal capable of withstanding significant mechanical stress and thermal cycling, making it a trusted component for demanding process applications.
Key Features
