ASTM A105 Flange

ASTM A105 Flange is a type of flange that is covered by a standard that covers pressure pipe and fittings that can operate under ambient temperature to high temperature services. Dinesh Industries is a supplier and manufacturer of flanges of all types. And so we produce and supply the A105 flange range as well. There are different standards that cover the different ASTM A105 flange dimensions which can be used with similar sized pipes. The wall thickness, the diameter, the material grade and the pressure classes all determine which kind of SA 105 flange could be used in a certain application.

Welding

These components can be welded. Welding procedures must comply with ASME Boiler and Pressure Vessel Code Section IX.

Forging

ASTM A105 carbon steel can be forged at temperatures in the range of 2200 to 1700 F followed by quenching and tempering or normalizing.

Annealing

Forged parts can be cooled to below 1000 degrees Fahrenheit and then heated to between 1550 degrees Fahrenheit and 1,700 degrees Fahrenheit. Then carry out slow furnace cooling.

Hydro-static Test

Hydro-static Test shall be conducted by the forging manufacture only when Supplemental S57 of ASTM A961 is specified.

Terminology

For definitions of other terms used in this specification, find in specification A961/A961M.

Ordering information

See specification A961/A961M.

General requirements

If conflict between the requirements of this specification and Specification A961/A961M. Comply with this specification.

Chemical Composition

A The sum of copper, nickel, chromium, molybdenum and vanadium shall not exceed 1.00%.
B The sum of chromium and molybdenum shall not exceed 0.32%.

Heat treatment

Heat treatment is not required except for flanges above Class 300, flanges of special design where the design pressure or design temperature are not known and for items over 4" NPS and above Class 300. When heat treatment is required, annealing, normalizing, Normalize and temper, normalize and quench and tempering shall be the applied methods.
