Class 125 Forged Carbon Steel Blind, Raised-Face Flange
Class 125 Forged Carbon Steel Blind Raised-Face Flange
The Class 125 Forged Carbon Steel Blind Raised-Face Flange provides a strong and durable solution for closing or isolating flanged openings in commercial and industrial piping systems. Featuring solid forged carbon steel construction and a raised-face sealing surface, this blind flange is designed for dependable performance when terminating piping runs, closing equipment connections, or isolating sections of a piping system.
Forged Carbon Steel Construction
Manufactured from forged carbon steel, the Class 125 blind flange offers excellent mechanical strength, toughness, and long-term durability. Forged steel provides a dense, uniform structure that makes these flanges suitable for demanding piping environments when properly specified.
Forged carbon steel blind flanges are commonly used in industrial processing, manufacturing, utilities, mechanical piping, water systems, power facilities, chemical processing, and general industrial piping applications.
Class 125 Blind Flange Design
A blind flange has no center bore and is specifically designed to close the end of a flanged pipe, valve connection, pressure vessel nozzle, or unused equipment opening. The solid flange creates a secure closure while retaining the convenience of a removable bolted connection.
Blind flanges provide valuable access for pressure testing, system isolation, inspection, cleaning, maintenance, piping modifications, and future system expansion.
Raised-Face Flange Construction
The raised-face (RF) design features an elevated gasket seating area around the center of the flange. This configuration concentrates bolting force over the gasket area, helping establish a dependable seal when used with a compatible mating flange and properly selected gasket.
Correct gasket type, bolting, mating flange, and installation procedures are important for reliable performance.
Class 125 Flange Selection
The Class 125 designation should be verified against the applicable dimensional and pressure standard, as Class 125 products can differ from standard forged-steel ASME pressure classes.
When ordering a Class 125 forged carbon steel blind raised-face flange, verify nominal pipe size, actual flange class, material specification, raised-face dimensions, dimensional standard, bolt pattern, gasket requirements, bolting, operating temperature, and service conditions to ensure proper piping system compatibility.
