What is blind flange

What is blind flange

A blind flange, also referred to as a blanking flange or blind plate, serves as a solid disk utilized to seal off or block a pipeline or vessel opening temporarily.  Its primary function is to halt the flow of fluids or gases within the system, often during maintenance, repair, or inspection activities. Manufactured from robust materials like carbon steel, stainless steel, or alloy steel, blind flanges are engineered to withstand high pressures, temperatures, and corrosive environments commonly encountered in industrial operations.  They are typically bolted onto the flange connection of the pipe or vessel using bolts and nuts, ensuring a secure and leak-free seal.

Available in a variety of sizes, shapes, and pressure ratings, blind flanges offer versatility to suit diverse applications across industries such as oil and gas, chemical processing, petrochemical, water treatment, and more. In addition to their sealing capabilities, blind flanges also serve as a safety measure by preventing accidental leaks or spills during system shutdowns or maintenance procedures.  They provide a reliable and cost-effective solution for temporarily isolating sections of pipelines or equipment, facilitating safe and efficient maintenance operations without compromising overall system integrity or performance.
