ASTM A106 Grade A/B Pipes, Tubes

ASTM specifications such as ASTM a106 Grade C are defined by the American Society for Testing and Measurements (ASTM). It is different from an ASTM A105 specification. ASTM specifications are published to help develop a standard for a wide range of products, materials, systems, and services.

ASTM a106 pipe is the normal specification for seamless carbon pipethat should be used when dealing with high-temperature service. These applications for high-temperature services include power plants, refineries, and boilers to only name a few. ASTM a106 comes in three steel grades which are stated as grades A, B, and C. The higher grade material that ASTM a106 receives, the strength of the pipe is better. The most common uses for a106 pipe is in plants or refineries when gases or fluids are transported at high temperatures and pressures. ASTM a106 is almost always produced by the seamless method and it can be bent, coiled, and flanged. In sizes less than 2” it is usually produced as a cold drawn product and in sizes above 2” it is usually produced as a hot finished product. Since a106 can be cold drawn or hot finished, the difference between the two is a matter of the temperatures at which the process is performed. The hot finished product is usually produced at temperatures that range around 1700F while the cold drawn product is produced at must lower temperatures while it contains more processing to finish. With that being said, cold drawn products usually have an improved surface finish and better dimension control.

The dimensions of the ASTM a106 pipe depends on the application that it is used for. The diameter of the ASTM a106 pipe usually is between 10.3 to 114.3mm in wall thickness. This diameter sizing depends on what grade is being used and the application the client is using this pipe for. The length of the ASTM a106 depends on the client’s needs and application also but it is usually between 0.8 to 12mm. The dimensions and sizing of the ASTM a106 pipe depend on the different applications that the pipe is being used for. If a client has a project that is larger, then he or she will use an a106 pipe that has a higher wall thickness and length.
