Class 125 Forged Carbon Steel Slip On, Flat-Face Flange
Class 125 Forged Carbon Steel Slip-On Flat-Face Flange
The Class 125 Forged Carbon Steel Slip-On Flat-Face Flange provides a strong, practical connection for commercial and industrial piping systems requiring a flat-face mating surface. Combining durable forged carbon steel construction with convenient slip-on installation, this flange is designed for connecting compatible pipe to valves, pumps, fittings, and other flanged equipment.
Forged Carbon Steel Construction
Manufactured from forged carbon steel, this Class 125 slip-on flange provides excellent mechanical strength, toughness, and long-term durability. The forging process creates a dense, uniform structure that helps provide dependable performance under piping loads when the flange is properly specified, fabricated, and installed.
Forged carbon steel flanges are commonly used in industrial processing, manufacturing, utilities, mechanical piping, water systems, power facilities, chemical processing, and general industrial piping applications.
Class 125 Slip-On Flange Design
A slip-on flange incorporates an internal bore that allows the flange to slide over the outside diameter of the connecting pipe. The pipe is positioned according to applicable fabrication requirements and typically secured using fillet welds.
Slip-on construction can simplify pipe positioning and bolt-hole alignment during fabrication and installation, making forged carbon steel slip-on flanges a practical option for many industrial piping systems.
Flat-Face Flange Construction
The flat-face (FF) design has a gasket seating surface extending across the flange face without the elevated sealing area found on a raised-face flange. Flat-face flanges can be used when connecting to compatible flat-faced valves, pumps, fittings, and other piping components.
Proper gasket selection, bolt loading, welding procedures, and mating-flange compatibility are important for achieving reliable sealing performance.
Class 125 Flange Selection
The Class 125 designation should be verified against the applicable dimensional and pressure standard, because Class 125 products may differ from standard forged-steel ASME pressure classes.
When ordering a Class 125 forged carbon steel slip-on flat-face flange, verify nominal pipe size, actual flange class, material specification, bore dimensions, flat-face configuration, dimensional standard, bolt pattern, gasket, bolting, welding requirements, temperature, and service conditions for proper industrial piping compatibility.
