Why Our Spectacle Blinds Stand Out
Positive Mechanical Isolation Spectacle Blinds – Ensures zero leakage and maximum pipeline safety
Heavy-Duty Spectacle Blinds for High Pressure & Temperature Applications
Wide Range of Spectacle Blinds Sizes & ANSI Pressure Classes Available
Custom Spectacle Blind Fabrication as per ANSI / ASME / API Standards
Clearly Marked Spectacle Blinds for Easy Identification & Safe Operation
Industrial Spectacle Blinds Designed for Hazardous & Critical Pipeline Isolation
Close Tolerance Manufacturing for Leak-Proof Spectacle Blind Installation
Durable Spectacle Blinds Suitable for Repeated Maintenance Shutdown Cycles
Working Principle - How Our Spectacle Blinds Work
A spectacle blind consists of two metal discs connected by a web:
One solid plate (blind) blocks flow completely
One open ring (spacer) allows full flow
How It Works:
Pipeline is depressurized
Spectacle blind is rotated
Solid plate or spacer is positioned between flanges
Bolting is tightened to ensure tight sealing
This provides absolute visual confirmation of pipeline open or closed condition.
