Class 1500 ASME A/SA105 ASME B16.5 Steel Flange
Class 1500 A/SA105 ASME B16.5 Steel Flange
The Class 1500 ASME A/SA105 ASME B16.5 Steel Flange is designed for demanding high-pressure industrial piping systems requiring exceptional strength, durability, and dependable sealing performance. Manufactured from forged carbon steel, these heavy-duty flanges provide secure connections for pipe, valves, pressure vessels, pumps, and other flanged equipment used in critical process applications.
ASTM A105 / ASME SA-105 Forged Carbon Steel
Manufactured from ASTM A105 / ASME SA-105 forged carbon steel, Class 1500 steel flanges provide excellent mechanical strength, toughness, and durability. A105/SA-105 is widely specified for pressure-containing piping components used throughout oil and gas, petroleum refining, petrochemical processing, chemical plants, power generation, manufacturing, utilities, and high-pressure industrial process piping systems.
Material selection should consider operating temperature, process media, environmental conditions, and applicable piping specifications.
Class 1500 High-Pressure Flange Applications
The Class 1500 designation identifies an ASME pressure class and should not be interpreted as a maximum working pressure of 1500 PSI. Actual allowable pressure depends on flange material, nominal pipe size, operating temperature, and applicable ASME pressure-temperature ratings.
Class 1500 forged steel flanges are intended for demanding piping systems requiring robust bolted connections and reliable performance under elevated pressure and temperature conditions.
Class 1500 Steel Flange Configurations
Depending on nominal pipe size and piping requirements, Class 1500 A/SA105 flanges may be available in weld neck, blind, threaded, socket weld, and other applicable configurations. Facing options can include raised face (RF) and ring-type joint (RTJ) where permitted by the applicable flange style, size, and standard.
ASME B16.5 Flange Requirements
ASME B16.5 establishes applicable requirements for flange dimensions, facings, bolt patterns, tolerances, materials, and pressure-temperature ratings.
When ordering a Class 1500 A/SA105 ASME B16.5 steel flange, verify nominal pipe size, flange style, facing, material specification, bore or pipe schedule, pressure class, gasket selection, bolting requirements, and operating conditions for dependable high-pressure industrial piping performance.
