Blind Flange Class 300 – ASTM A105N (ASME B16.47 Series B)

Forged Carbon Steel Blind Flange for High-Pressure Piping Systems

Description

Our Blind Flanges, manufactured from ASTM A105N forged carbon steel in accordance with ASME B16.47 Series B, are designed to safely seal or terminate the ends of piping systems, pressure vessels, and process equipment operating under high-pressure conditions.

Engineered for exceptional strength, dimensional accuracy, and leak-tight performance, these blind flanges are widely used in the oil & gas, petrochemical, power generation, water treatment, and industrial processing industries. They provide secure isolation of pipelines while allowing easy access for future inspection, maintenance, pressure testing, or system expansion.
