ASTM A105 Flanges

ASTM A105 Flanges are carbon steel forged flanges used in pressure-containing piping and industrial systems.

They are commonly supplied for connecting pipes, valves, pumps, pressure vessels and other piping components. A105 flanges can be manufactured in different configurations according to the required pressure class, size, facing and piping design.

ASTM A105N Flanges

ASTM A105N Flanges are A105 carbon steel forgings supplied in the normalized condition where required by the applicable specification or purchase order.

A105N flanges are available in Weld Neck, Blind, Slip-On and other suitable configurations. Normalized material requirements are particularly important when specified by the project, engineering standard or customer specification.

A105 / A105N Flange Standards

A105 and A105N flanges can be supplied according to applicable standards including:

ASTM A105 / ASME SA105, ASME B16.5, ASME B16.47 and other dimensional standards such as EN 1092-1, DIN, JIS and BS where applicable.

Flange dimensions are controlled according to the selected standard, including outside diameter, thickness, bore, bolt-hole arrangement, PCD and facing.

Specifications

A105 / A105N Flanges are available in a wide range of nominal sizes depending on the selected flange type and applicable standard.

Pressure classes can include Class 150, 300, 400, 600, 900, 1500 and 2500, subject to size, flange configuration, material and applicable standard.

Available facing options include:

Raised Face (RF), Flat Face (FF) and Ring Type Joint (RTJ) where applicable.

Special bore sizes, flange thicknesses, bolt-hole arrangements, facing finishes and other dimensions can be supplied against approved drawings or technical specifications.

Difference Between A105 and A105N

The basic material specification is ASTM A105 carbon steel forging. The “N” in A105N refers to normalized material condition.

A105 and A105N should therefore not be treated as two completely different base materials. The required material condition should be selected according to the applicable specification, engineering requirement or purchase order.

Applications

A105 and A105N flanges are used in various industrial piping systems, including:

• Oil & Gas Pipelines

• Refineries

• Petrochemical Plants

• Chemical Industries

• Power Generation

• Steam Piping

• Process Piping

• Pressure Systems

• Water and Utility Piping

• Industrial Equipment

• Plant Maintenance

The correct flange material and configuration should always be selected according to operating pressure, temperature, fluid service and applicable engineering requirements.

Manufacturing & Inspection

Vandan Alloys supplies A105 / A105N flanges according to specified material and dimensional requirements.

Inspection can include chemical composition, mechanical properties, dimensional inspection, visual inspection, hardness testing, PMI and other tests when specified.

Material Test Certificates can be provided, including EN 10204 Type 3.1 documentation where required. Third-party inspection can also be arranged according to customer or project requirements.

We also supply custom A105 and A105N flanges manufactured according to customer drawings.

Special requirements such as:

• Non-standard thickness

• Special bore

• Customized PCD

• Special bolt-hole arrangement

• Modified facing

• Counterbore

• Special flange dimensions

can be reviewed based on drawing and technical specification.
