What are the two most common carbon steel pipe materials?

• A. A333 & A106
• B. A53 & A106
• C. A106 & A333
• D. A53 & A512

Answer: (B)

Two carbon steel pipe materials you’ll encounter most often are A53 and A106. A53 is the general-purpose carbon steel pipe used for conveying liquids and gases under pressure, including black and galvanized varieties, so it covers a broad range of everyday piping needs. A106 is seamless pipe designed for high-temperature service, making it the go-to choice where heat resistance and strength are required in process and refinery piping. Other options exist, but A333 is focused on low-temperature service (more specialized), and A512 is tubing rather than pipe, so it isn’t part of the common pipe material pair.
