Class 150 Forged Carbon Steel Slip On, Flat-Face Flange
Class 150 ASTM A105 / ASME SA-105 Slip On Flange
The Class 150 ASTM A105 / ASME SA-105 Forged Carbon Steel Slip On Flat-Face Flange provides a durable and economical connection for industrial piping systems. Manufactured from high-quality forged carbon steel, this flange combines dependable mechanical strength with straightforward installation for manufacturing, utilities, process piping, power generation, petrochemical, and general industrial applications.
ASTM A105 / ASME SA-105 Forged Carbon Steel
Manufactured from ASTM A105 / ASME SA-105 forged carbon steel, this slip on flange provides the strength and durability required for pressure-containing piping applications. A105/SA-105 carbon steel is widely specified for forged steel flanges, fittings, valves, and related industrial piping components.
The Class 150 designation identifies the flange pressure class rather than a maximum working pressure of 150 PSI. Actual allowable pressure depends on material, system temperature, and applicable ASME pressure-temperature ratings.
Slip On Flange Design
A slip on flange features a bore larger than the outside diameter of the matching pipe, allowing the flange to slide over the pipe for convenient positioning and alignment. After positioning, the flange is typically attached using fillet welds on the inside and outside.
This installation method makes carbon steel slip on flanges a practical choice for many industrial piping installations.
Flat-Face Flange Configuration
The flat-face (FF) flange has a gasket seating surface extending across the flange face without the elevated sealing area found on a raised-face flange. Flat-face flanges are commonly used when mating with compatible flat-face valves, fittings, pumps, or equipment.
Class 150 A105/SA-105 slip on flanges may be manufactured to ASME B16.5 requirements for applicable sizes, covering dimensions, facing, bolt patterns, tolerances, and pressure-temperature ratings.
When ordering a Class 150 A105/SA-105 slip on flat-face flange, verify nominal pipe size, pressure class, facing, material specification, and applicable dimensional standard to ensure proper fit and dependable service.
