Class 125 Forged Carbon Steel Slip On, Raised-Face Flange
Class 125 Forged Carbon Steel Slip-On Raised-Face Flange
The Class 125 Forged Carbon Steel Slip-On Raised-Face Flange provides a strong, practical, and economical connection for commercial and industrial piping systems. Combining durable forged carbon steel construction, convenient slip-on installation, and a raised-face sealing surface, 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 produces a dense, uniform structure that helps the flange withstand demanding piping loads when properly specified 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 to the flange using fillet welds.
Slip-on construction can simplify pipe positioning and bolt-hole alignment during fabrication and installation. This makes forged carbon steel slip-on flanges a practical choice for many piping systems where installation efficiency and reliable welded connections are important.
Raised-Face Flange Construction
The raised-face (RF) design features an elevated gasket seating surface that concentrates bolting force over the gasket area. When combined with a compatible mating flange and correctly selected gasket, the raised face helps establish a dependable seal.
Proper gasket selection, bolting, welding procedures, and mating-flange compatibility should always be confirmed.
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 raised-face flange, verify nominal pipe size, actual flange class, material specification, bore dimensions, raised face, dimensional standard, bolt pattern, gasket, welding requirements, operating temperature, and service conditions.
