ASTM A106 is a specification for seamless carbon steel pipe for high-temperature service. It has a maximum carbon content of 0.30% and a maximum manganese content of 1.20%, making it a low-carbon steel with good strength and toughness. This material is suitable for use in high-temperature and high-pressure applications, such as power generation, chemical processing, and petroleum refining. Additionally, it has excellent corrosion resistance and can be used in outdoor environments without requiring additional protection.

The normal use cases for ASTM A106 include transportation of fluids and gases, as well as structural applications in the construction industry. It is also commonly used in the manufacturing of boilers, heat exchangers, and pressure vessels. Its strength, toughness, and corrosion resistance make it a popular choice for a wide range of applications that require durability and reliability in high-temperature environments.

At, ASTM A106 is available in black galvanized steel pipe. The black steel pipe is available in sizes ranging from 1/2 inch to 3 inches in diameter. The galvanized steel pipe is available in lengths from 1 foot to 8 feet and can be custom cut to length. Both types of steel pipe are available in standard and extra-heavy wall thicknesses to accommodate different application requirements.
