Product Overview
A blind flange, also known as a blanking flange or pipe plug, is a solid disc-type flange with no center bore. Its primary function is to reliably isolate or seal off pipe, valve, or equipment openings. It is a crucial component in pressurized piping systems, used for situations requiring complete fluid shut-off, system isolation, or future connection points, ensuring operational safety and system segmentation.
Product Features
Reliable Sealing: The blind flange is bolted between mating flanges with a gasket, achieving a leak-tight seal that effectively isolates the medium within the pipeline.
Robust Structure: Typically manufactured from materials like carbon steel plate, forged steel, or stainless steel, it features a solid construction capable of withstanding pressure ratings identical to its mating flange, ensuring reliable isolation.
Diverse Types: Based on the facing type, main categories include Raised Face (RF) and Flat Face (FF) to match different flange standards. Additionally, a special "Spectacle Blind" (resembling a figure-8, with one solid end and one hollow end) is used for applications requiring temporary switching between open and closed states.Main Applications
Blind flanges are widely used across various industrial piping systems.
-
System Isolation & Maintenance: Used for the reliable isolation of specific pipe sections during equipment repair, segment pressure testing, or system cleaning to ensure operational safety.
-
Future Connection Reservations: Used to temporarily seal reserved ports for potential future branch connections during the initial construction or modification of piping systems.
-
Plant Startup/Shutdown: Employed for process isolation in continuous production facilities such as petrochemical and oil refining plants. It is a standard safety measure within plant startup, shutdown, and maintenance procedures.
