ASTM A106 Seamless Carbon Steel Pipe


ASTM A106 is a standard specification for seamless carbon steel pipe used in high-temperature service. The pipe is commonly used in refineries, power plants, and industrial plants to transport fluids and gases at high temperatures and pressures.

The ASTM A106 seamless carbon steel pipe is made of high-quality carbon steel alloy, ensuring its durability and resistance to corrosion. It has a consistent composition and mechanical properties, making it suitable for various applications in different industries.

This seamless pipe is manufactured by a seamless hot-finished process, which involves heating a solid billet of carbon steel and then rolling it into a tube shape. The absence of any weld seams in the pipe enhances its strength, reliability, and ability to withstand high-pressure conditions. This seamless construction also helps prevent leaks and ensures smooth flow of fluids.

The ASTM A106 pipe is available in different sizes and specifications to meet the requirements of various applications. It can accommodate high-temperature fluids and gases, making it suitable for steamlines, superheaters, and high-pressure applications. It is designed to withstand operating temperatures ranging from -29ºC (-20ºF) to 425ºC (800ºF).

Additionally, ASTM A106 seamless carbon steel pipe is known for its excellent mechanical properties, including high tensile strength and yield strength. This ensures its ability to handle the stress and pressure involved in demanding applications.

Overall, ASTM A106 seamless carbon steel pipe offers outstanding performance and reliability in high-temperature and high-pressure environments. Its quality material, seamless construction, and precise specifications make it a preferred choice in a wide range of industrial applications.

Seamless Carbon Steel Pipe 4

ASTM A106 / ASME SA106 pipes are seamless carbon steel pipes used for high tempertaure applications (up to 750 degrees F). These pipes are widely used in the oil & gas, petrochemical, power generation and ship-building industries (examples: refineries, downstream plants, vessels. boilers and towers). A106 pipes are particularly suited whenever the transported fluid has either high temperature or high pressure (or both combined).

In terms of material grades, A106 pipes are manufactured in grade A, B and C. NPS 1-1/2? and below are available in the hot finished or by cold drawn type. Pipes of NPS 2 inch and above are generally are hot rolled manufatured. A106 pipes are produced out of killed steel. The chemical composition and Machanical Property of the three grades of ASTM A106 is shown in the following table:

Chemical composition:

Chemical composition, %
A106 Grade A0.250.27-0.930.0350.0350.100.400.400.150.400.08
A106 Grade B0.300.29-1.060.0350.0350.100.400.400.150.400.08
A106 Grade C0.350.29-1.060.0350.0350.100.400.400.150.400.08
