ASTM A106 Grade B Pipe (A106M – 18) is a Standard Specification for Seamless Carbon Steel Pipe for High-Temperature Service. ASTM A106 pipe is constantly delivered by the seamless method and can be bent, coiled and flanged. Carbon steel astm a106 pipe, ASTM A106 Grade B Pipe sizes, less than 2″ is it normally delivered as a cold drawn product. 2″ and up are usually hot finished. SA106 pipe is expected for use in high temperature applications. General characteristics steel seamless pipe grade A106 / A106M.- is steel for high temperature service, it is a steel that enables bending, welding and flanged among other tasks.
