Class 1500 Forged Carbon Steel Slip On, Raised-Face Flange
Class 1500 A/SA105 Forged Carbon Steel Slip-On Raised-Face Flange
The Class 1500 ASME A/SA105 Forged Carbon Steel Slip-On Raised-Face Flange manufactured to ASME B16.5 provides a strong, heavy-duty connection for demanding high-pressure industrial piping systems. Combining forged carbon steel construction, convenient slip-on installation, and a raised-face sealing surface, this flange delivers strength, durability, and dependable performance in critical process piping applications.
ASTM A105 / ASME SA-105 Forged Carbon Steel
Manufactured from ASTM A105 / ASME SA-105 forged carbon steel, this Class 1500 slip-on flange offers excellent mechanical strength, toughness, and long-term durability. A/SA105 is widely specified for pressure-containing piping components used in oil and gas, petroleum refining, petrochemical processing, chemical plants, power generation, manufacturing, utilities, and industrial process piping systems.
Material suitability should always be evaluated for operating temperature, process media, corrosion conditions, and overall piping system requirements.
Class 1500 Slip-On Flange Design
A slip-on flange features 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 secured with fillet welds using the specified welding procedure.
Slip-on construction can simplify flange positioning and bolt-hole alignment during piping fabrication and installation.
The Class 1500 designation represents an ASME pressure class rather than a maximum working pressure of 1500 PSI. Actual allowable pressure depends on material, flange size, operating temperature, and applicable pressure-temperature ratings.
Raised-Face Flange Construction
The raised-face (RF) design incorporates an elevated gasket seating area that concentrates bolting force over the gasket. With a compatible mating flange and properly selected gasket, this configuration helps provide a dependable seal.
ASME B16.5 Flange Requirements
ASME B16.5 establishes applicable requirements for flange dimensions, facing dimensions, bolt patterns, tolerances, and pressure-temperature ratings.
When ordering a Class 1500 A/SA105 slip-on raised-face flange, verify nominal pipe size, bore dimensions, Class 1500 rating, A/SA105 material, raised face, ASME B16.5 requirements, gasket selection, bolting, welding procedures, and service conditions.
