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

Description

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

Engineered for superior strength, durability, 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 convenient access for future inspection, maintenance, or system expansion while ensuring secure isolation of pipelines.
