Product Description

What is a blind flange?

A blind flange (also called a 'closure plate flange') is installed at the end of a piping system to terminate a pipe. It has no centre hole (bore), so there is no flow through the flange. A blind flange may be used for isolating a pipe, valve, or pressure vessel. This type of flange is available in all sizes and classes, and may use a flat, raised, or ring-type joint face.
A blind flange can replace a butt weld cap in case an extension of the piping line is required, or in case a piping inspection is required (remove the blind flange to access the pipe interior). This type of flange can also be used as the rod access point on drain systems. Depending upon the application, a blind flange may be drilled and used as a slip-on flange, or tapped and used as a threaded flange.

Key Features of Blind Flanges:

Purpose:Blind flanges are used to close off the ends of pipes, valves, or other equipment, providing a secure seal.
Design:They are typically flat and have no central opening, which distinguishes them from other types of flanges that allow for flow.
Material:Blind flanges can be made from various materials, including carbon steel, stainless steel, and alloy materials, depending on the application and environmental conditions.
Applications:Commonly used in oil and gas, chemical processing, water treatment, and other industrial applications where a secure closure is needed.
Installation:Blind flanges are bolted to the piping system, and gaskets are often used to ensure a tight seal and prevent leaks.
