Class 600 Forged Carbon Steel Slip On, Raised-Face Flange
Class 600 A105/SA-105 Slip-On Raised-Face Flange
The Class 600 ASTM A105 / ASME SA-105 ASME B16.5 Forged Carbon Steel Slip-On Raised-Face Flange provides a strong, practical connection for demanding industrial pressure piping systems. Combining forged carbon steel construction, convenient slip-on installation, and a raised-face sealing surface, this flange delivers dependable strength and durability for heavy-duty commercial and industrial piping applications.
ASTM A105 / ASME SA-105 Forged Carbon Steel
Manufactured from ASTM A105 / ASME SA-105 forged carbon steel, this Class 600 slip-on flange offers excellent mechanical strength, toughness, and durability. A105/SA-105 is widely specified for pressure-containing components used throughout oil and gas, petrochemical processing, refineries, power generation, chemical processing, manufacturing, utilities, and industrial process piping systems.
The Class 600 designation identifies an ASME pressure class rather than a maximum working pressure of 600 PSI. Actual allowable pressure depends on material, operating temperature, flange size, and applicable pressure-temperature ratings.
Class 600 Slip-On Flange Design
A slip-on flange incorporates a bore that allows the flange to slide over the outside diameter of the connecting pipe. This design provides convenient positioning and alignment during piping fabrication before welding.
The pipe is typically positioned slightly back from the flange face and secured using fillet welds in accordance with applicable welding procedures and piping specifications. Proper flange selection must account for the required pressure class, pipe dimensions, operating conditions, and system design.
Raised-Face Flange Construction
The raised-face (RF) flange features an elevated gasket seating surface surrounding the bore. This design concentrates bolting force over the gasket area, helping create a dependable seal between compatible mating flanges.
Manufactured to applicable ASME B16.5 requirements, Class 600 A105/SA-105 slip-on flanges provide standardized dimensions, bolt patterns, facing requirements, and pressure-temperature ratings.
When ordering, verify nominal pipe size, Class 600 rating, raised-face configuration, A105/SA-105 material, ASME B16.5 dimensions, gasket selection, bolting, and service conditions for reliable industrial piping performance.
