Blind Flange

Key Features

Blind Flanges are used to close the ends of piping systems, valves, and pressure vessel openings. These flanges do not have a bore and are designed to block the flow of fluids, making them essential for maintenance, inspection, and testing purposes. Blind Flanges are capable of handling high pressure and temperature conditions due to their solid construction.

SAKSHI FORGE manufactures high-quality Blind Flanges using premium stainless steel materials. These flanges are widely used in oil & gas, petrochemical, power plants, and water treatment industries. They provide flexibility in system design, allowing future expansion or modification of pipelines.

Blind Flanges are available in different pressure classes and face types. They are designed to withstand internal pressure and mechanical loads without deformation. Due to their strength, they are often used in high-pressure applications where safety is critical.
