ASTM A106 Hot Rolled Carbon Steel Seamless Pipe-Carbon steel pipe-yaogang-steel

A106 carbon steel pipe is a type of seamless pipe made from carbon steel, specifically designed for high-temperature and high-pressure applications. It is primarily used for transporting steam, water, gas, and oil in various industries, including oil and gas, chemical processing, power plants, and construction.

Here are some key features of A106 carbon steel pipes:

Material Composition: A106 pipes are made from carbon steel, with a high percentage of carbon content, which gives them strength and durability.

Grades: The A106 pipe is available in three grades:

Grade A: Suitable for low-pressure applications.

Grade B: Most commonly used grade, known for its medium strength and resistance to high pressure.

Grade C: Offers higher strength and is used for more demanding applications.

Seamless Construction: A106 pipes are seamless, meaning they have no weld seams, which makes them stronger and more reliable under high-pressure conditions.

Applications: A106 pipes are often used in the oil and gas industry, power generation, refineries, and petrochemical plants. They are ideal for applications requiring the transportation of fluids and gases at high temperatures and pressures.

Standards: A106 pipes are manufactured according to the ASTM A106/A106M standard, which ensures that the pipes meet specific mechanical properties and quality criteria.

Temperature and Pressure Resistance: These pipes are suitable for use in temperatures up to 750°F (399°C) and can handle high pressure, making them ideal for power plant and industrial applications.

Overall, A106 carbon steel pipes are known for their strength, reliability, and ability to withstand harsh operating conditions.

Manufacturing & Testing Requirements for A106 Seamless Pipes

Heat Treatment	Hot-finished pipe need not be heat treated. Cold-drawn pipe shall be heat treated after the final cold draw pass at a temperature of 1200 °F (650 °C) or higher.
Process	The steel shall be killed steel, with the primary melting process being open-hearth, basic-oxygen, or electric-furnace, possibly combined with separate degassing or refining. If secondary melting, using electroslag remelting or vacuum-arc remelting is subsequently employed, the heat shall be defined as all of the ingots remelted from a single primary heat. Steel cast in ingots or strand cast is permissible. When steels of different grades are sequentially strand cast, identifi- cation of the resultant transition material is required. The producer shall remove the transition material by any estab- lished procedure that positively separates the grades.
Surface Treatment	Oil-dip, Varnish, Passivation, Phosphating, Shot Blasting
Hydrostatic Testing	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.
Nondestructive Electric Test	The full body of each pipe shall be tested with a nondestructive electric test in accordance with Practice E 213, E 309, or E 570.
Mechanical Tests Specified	Tensile Test — NPS 8 and larger — either transverse or longitudinal acceptable smaller than NPS 8 — weighed in lots. Larger Sizes — by length. Flattening Test — NPS 2-1/2 and larger. Bending Test (Cold) — NPS 2 and under.

Test Before Delivery
