Class 125 ASME A/SA105 ASME B16.5 Steel Flange
Class 125 A/SA105 ASME B16.5 Steel Flange
The Class 125 ASME A/SA105 ASME B16.5 Steel Flange provides a strong and dependable connection for commercial and industrial piping systems. Manufactured from forged carbon steel, these flanges offer excellent mechanical strength and durability for connecting pipe, valves, pumps, fittings, and other flanged equipment in a wide range of piping applications.
ASTM A105 / ASME SA-105 Forged Carbon Steel
ASTM A105 / ASME SA-105 forged carbon steel is widely specified for pressure-containing piping components because of its strength, toughness, and dependable performance. A105/SA-105 steel flanges are commonly used in industrial processing, manufacturing, mechanical piping, utilities, water systems, power facilities, chemical processing, and general industrial piping systems.
Proper material selection should always consider the operating temperature, process media, corrosion conditions, and overall piping system requirements.
Class 125 Steel Flange Applications
Class 125 flanges are commonly associated with piping systems and equipment requiring a lower-pressure flange connection. Depending on the system design, steel flanges may be used to connect to compatible valves, pumps, strainers, fittings, and other flanged components.
Because Class 125 and Class 150 designations come from different flange standards and material families, they should not automatically be considered identical or interchangeable. Dimensions, facing, bolt patterns, pressure-temperature ratings, and mating component requirements should be confirmed before installation.
Available Steel Flange Configurations
Depending on size and application requirements, A/SA105 forged carbon steel flanges may be supplied in various configurations, including threaded, slip-on, blind, weld neck, socket weld, and lap joint styles, where applicable.
ASME B16.5 Flange Requirements
ASME B16.5 provides requirements for applicable flange dimensions, materials, facings, tolerances, bolting, and pressure-temperature ratings.
When specifying a Class 125 A/SA105 steel flange, verify the nominal pipe size, actual pressure class, flange style, facing, bolt pattern, material specification, mating component, gasket requirements, and dimensional standard to ensure proper fit and dependable industrial piping performance.
