Class 150 Forged Carbon Steel Slip On, Raised-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 Flange with Raised Face provides a practical, durable solution for connecting pipe in industrial pressure piping systems. Manufactured from forged carbon steel, this flange is widely used in manufacturing, utilities, petrochemical processing, power generation, mechanical contracting, and general industrial piping applications.
ASTM A105 / ASME SA-105 Forged Carbon Steel
Manufactured from ASTM A105 / ASME SA-105 forged carbon steel, this Class 150 slip on flange offers excellent mechanical strength, durability, and dependable performance. A105/SA-105 is commonly specified for forged pressure-containing piping components, including steel flanges, fittings, and valves.
The Class 150 designation represents the ASME pressure class and does not indicate a maximum pressure of 150 PSI. Allowable working pressure depends on material, operating temperature, and applicable pressure-temperature ratings.
Slip On Flange Design
A slip on flange is designed with a bore slightly larger than the outside diameter of the connecting pipe, allowing the flange to slide over the pipe during installation. Once properly positioned, the flange is typically secured using fillet welds at the inside and outside connections.
This configuration can simplify alignment and installation compared with some other welded flange designs.
Raised-Face Flange Construction
The raised-face (RF) flange incorporates an elevated gasket seating surface around the bore. Concentrating the bolting load over this smaller gasket area helps create an effective seal between compatible mating flanges.
Class 150 A105/SA-105 slip on flanges are commonly manufactured according to ASME B16.5 requirements for applicable sizes. B16.5 establishes dimensional, facing, bolting, tolerance, and pressure-temperature requirements.
When selecting a Class 150 A105/SA-105 slip on raised-face flange, verify nominal pipe size, pressure class, facing, material, pipe dimensions, and applicable piping specifications for proper installation and reliable industrial service.
