ASTM A105 is a specification for carbon steel forgings for piping applications. The specification covers a range of carbon steel forgings, including flanges, fittings, valves, and similar parts, that are intended for use in pressure systems at ambient and high-temperature service conditions.

ASTM A105 flanges are one of the most commonly used types of flanges in the piping industry. These flanges are designed to connect pipes, valves, and other equipment in a piping system. They are available in a variety of sizes, shapes, and pressure ratings, and can be used in a wide range of applications, from low-pressure systems to high-pressure and high-temperature systems.

ASTM A105 flanges are typically made from carbon steel, which provides good strength, ductility, and corrosion resistance. They are available in various grades, including ASTM A105N, which indicates that the flanges have been normalized to improve their mechanical properties. ASTM A105 flanges can also be supplied in various finishes, including black, galvanized, and painted.

When specifying ASTM A105 flanges, it is important to consider factors such as the size, pressure rating, and temperature rating of the flanges, as well as the material of the pipes and equipment they will be connected to. It is also important to ensure that the flanges are installed correctly and according to industry standards to ensure the integrity and safety of the piping system.
