Class 150 ASME A/SA105 ASME B16.5 Hot Dipped Galvanized Steel Flange
Class 150 A/SA105 B16.5 Hot-Dipped Galvanized Steel Flange
The Class 150 ASME A/SA105 ASME B16.5 Hot-Dipped Galvanized Steel Flange combines the mechanical strength of forged carbon steel with a protective zinc coating for improved corrosion resistance. Designed for commercial and industrial piping systems, these galvanized steel flanges provide dependable connections for pipe, valves, fittings, pumps, and other flanged equipment.
ASTM A105 / ASME SA-105 Forged Carbon Steel
Manufactured from ASTM A105 / ASME SA-105 forged carbon steel, Class 150 steel flanges provide excellent strength, toughness, and durability. A105/SA-105 is widely specified for pressure-containing piping components used in industrial processing, manufacturing, utilities, water systems, mechanical piping, fire protection, and general-purpose piping applications where appropriate.
The Class 150 designation represents an ASME pressure class rather than a maximum operating pressure of 150 PSI. Actual allowable pressure depends on material, operating temperature, flange size, and applicable pressure-temperature ratings.
Hot-Dipped Galvanized Protective Finish
A hot-dipped galvanized steel flange receives a protective zinc coating that helps shield the underlying carbon steel from corrosion. The galvanized finish makes these flanges particularly useful for piping installations exposed to moisture, humid environments, outdoor conditions, and other corrosive atmospheric conditions.
The suitability of galvanized steel for a particular process fluid, temperature, or chemical environment should always be verified before installation.
Available Class 150 Flange Configurations
Depending on size and application, Class 150 galvanized A/SA105 flanges may be available in threaded, slip-on, blind, weld neck, socket weld, and other applicable configurations, with appropriate flange-facing options.
ASME B16.5 Flange Requirements
ASME B16.5 establishes applicable flange dimensions, bolt patterns, facing requirements, tolerances, and pressure-temperature ratings.
When ordering a Class 150 A/SA105 hot-dipped galvanized steel flange, verify nominal pipe size, flange style, facing, material specification, galvanizing requirements, ASME B16.5 dimensions, gasket selection, and service conditions for proper industrial piping system compatibility.
