Check Specification of Carbon steel A105N Pipe Flange and Blind Flange A105N.


ASTM A105N Flange is made up of a carbon steel that is strong, hard and tough. R.C. Metal Corporation is a leading manufacturer and supplier of the Carbon steel A105N Pipe Flange products in different dimensions. The sizes range from 1/16 inches to 5/16 inches in nominal bore size. There are different types of the flanges such as the Blind Flange A105N which is used to terminate a pipe line. There are others that connect pipes together with different types of connection.


ASTM A105N Flange

ASTM A105N Flange

The A105n Flange material has carbon, manganese, silicon, sulfur, phosphorus and minimum amounts of alloying elements. There are different types such as the orifice flange a105n which are used for specific purposes. The strength of the A105N Flange material is at 250MPa minimum yield strength and 585MPa minimum tensile strength. The carbon steel is used for its hardness and high wear and tear resistant properties. The ASME SA105N Flanges can be seamless or welded.

The forging and annealing is done to improve the flange strength further. The different face types include flat face, raised face and the ring type joint. The different functional types include the ASTM A105N Reducing flange which reduces the pipe diameter at connection. The pipes sometimes need to be connected with high precisions. The ASTM A105N Slip on flange allows the pipe to be slipped onto the flange. The seamless pipes often require slip on flanges to fit them for the higher dimensional accuracy.
