ASTM A106 Gr.B seamless steel pipe

ASTM A106 Gr.B Seamless steel pipe

ASTM A106 Gr.B A seamless carbon steel pipe material in line with ASTM standards, the steel pipe made of this material is specially used for transportation under various high temperature and high pressure environments, often used in oil, natural gas, chemical, electric power and other industries, for conveying high temperature water, gas, oil and so on.

Production process:
It is basically consistent with the production process of seamless optical tubes. Killed steel, with primary melting process being open-hearth, basic-oxygen, or electric-furnace,  possibly combined with separate degassing or refining.Steel cast in ingots or strand cast is permissible. Among them, the hot working pipe does not need heat treatment, and the cold drawn pipe should be heat treated after the last cold drawing.

Chemical composition:

Main component	Carbon	Manganese	Phosphorous	Sulfur	Silicon	Chrome	Copper	Molybdenum	Nickel	Vanadium
Content max.%	0.30	0.29 to 1.06	0.035	0.035	0.10	0.40	0.40	0.15	0.40	0.08
Note:Unless otherwise specified by the purchaser, for each reduction of 0.01% below the specified carbon maximum, an increase of 0.06% manganese above the specified maximum will be permitted up to a maximum of 1.65%

Mechanical properties:

	Grade B
Tensile Strength, min., psi	60,000
Yield Strength, min., psi	35,000

Hydraulic test:

Inspection test pressures produce a stress in the pipe wall equal to 60% of specified minimum yield strength (SMYS) at  room temperature. Maximum Pressures are not to exceed 2500 psi for NPS3 and must stay under 2800 psi for the larger  sizes. Pressure is maintained for not less than 5 seconds.

Application field:
ASTM A106 Gr.B Seamless steel pipes are commonly used to transport fluids at high temperature and pressure, suitable for applications such as:
Boiler pipe: used to transport high temperature steam and water.
Oil and gas industry: for the transmission of oil and gas.
Oil refinery, power plant: used to transport high temperature fluid, for heat exchange equipment.
Ship construction: Can be used for pressure parts and structural support.

In summary:
ASTM A106 Gr.B Seamless steel pipe is a high strength, high temperature, pressure resistant seamless carbon steel pipe, widely used in high temperature and high pressure environment fluid transport and industrial equipment manufacturing. Its strict chemical composition and mechanical performance requirements ensure the stability and reliability of the product and are the preferred material in piping systems.
