ASTM ASME A SA 150 (N) Male Face Flanges

Carbon steel forgings, manufactured in accordance with ASTM A105, are generally used for piping applications. These forged carbon steel piping components (including flanges, fittings, and valves, etc) are used for ambient- and higher-temperature service in pressure systems.

If the forgings are used for piping applications of ASME BPVC or ASME B31, the material shall be its identical equivalent of SA-105 or SA-105N. In short, the heat treatment of normalization distinguishes A105N from A105, or SA-105N from SA-105. SA 105 flange is a specification of flanges. The specification can include different grades of stainless steel material made flanges. The SA 105 flanges are of forged carbon steel and are meant for high temperature services.

 

The SA 105 flange is second most used joining method after welding. A105 flanges are used when joints need dismantling. ASTM A105 forged steel flanges provides flexibility for maintenance.flange connnects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.

 

A105 flanged joint is composed of three separate and independent although interrdlated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls are required in the selection and application of all these elements to attain a joint, which has acceptable leak tightness.
SA 105 flanges are used to connect 2 ends of a pipe or to end a pipe. A105 forged steel flanges are available in various materials. Carbon Steel Flanges are one such type of flange that is usually made up of carbon steel. SA 105 flange provides properties such as resistance to corrosion, excellent durability, and finishing in goods.
