Stainless steel spectacle flanges

Stainless steel spectacle flanges introduction

Stainless steel spectacle flanges, also known as stainless steel spectacle blind flanges, are most commonly used on piping systems that need to be separated regularly or where the flow through the system is regularly stopped. The spectacle flange can be rotated to place either the solid or hollow end within the pipe system, thereby opening or closing the flow.
