Frequently Asked Questions About ASTM A105 Flanges

Technical and purchasing questions commonly considered when sourcing A105 carbon steel flanges for United States projects.

What is ASTM A105 carbon steel flange?

An ASTM A105 carbon steel flange is a forged carbon steel piping component manufactured from material specified by ASTM A105. A105 flanges are used for specified pressure piping and industrial applications where the material and design requirements are suitable.

What is the difference between ASTM A105 and ASME SA105?

ASTM A105 is the ASTM material specification designation, while SA105 is the corresponding ASME material specification designation used within the ASME Boiler and Pressure Vessel Code framework. The applicable designation should be selected according to the governing project and engineering specification.

Which types of ASTM A105 flanges are available?

A105 flanges can be supplied in configurations such as slip-on, weld neck, blind, threaded, socket weld, lap joint, orifice, RTJ and other project-specific designs, subject to the applicable manufacturing and dimensional requirements.

What pressure classes are available for A105 flanges?

Common ASME pressure classes include Class 150, 300, 400, 600, 900, 1500 and 2500. Availability depends on flange type, size, applicable dimensional standard and the specific order requirements.

Which standards are used for A105 flange dimensions?

Depending on the flange type and size, dimensional requirements may be specified to standards such as ASME B16.5 or ASME B16.47. The applicable standard should be confirmed against the project specification before ordering.

Can you supply ASTM A105 flanges to customers in the United States?

Yes. Creative Piping Solutions supplies products for customers and projects in the United States. Buyers can submit their required flange type, size, pressure class, facing, quantity, documentation and delivery requirements for quotation.

What information is required for an A105 flange quotation?

For an accurate quotation, provide the flange type, NPS or nominal size, pressure class, facing, applicable standard, quantity, inspection requirements, documentation requirements and delivery location. Drawings or a project BOM can also be submitted where applicable.

Can third-party inspection be arranged for A105 flanges?

Third-party inspection can be arranged according to customer and project requirements. Inspection requirements should be specified when submitting the RFQ so they can be considered during the quotation and production process.

Can I request a quotation for a complete A105 flange BOM?

Yes. Customers can submit a complete bill of materials, drawings or project specification for technical and commercial review rather than requesting each flange individually.
