ASTM A106 ASME SA106 Pressure Pipe

ASTM A106/ ASME SA106 seamless Pressure pipe

ASTM/ ASME A106/SA106 Seamless Carbon Steel Pipe

ASTM A106/ ASME SA106  Pressure pipe are manufactured in cold-drawn and  hot finish seamless, material in low carbon steel  for transporting fluids and gases at high temperatures and pressures for example: boiler systems, heat exchangers, power plants, refineries, and other high-temperature applications.

ASTM A106 is a standard specification for seamless carbon steel pipe for high-temperature service. It covers various grades of carbon steel pipe, including Grade A, Grade B, and Grade C, which are used in different applications based on their mechanical properties.

Mechanical Properties of ASTM A106/ ASME SA106 seamless Pressure pipe：

Grade and Chemical Composition (％) of ASTM A106/ ASME SA106 seamless Pressure pipe

ASTM A 106 Grade B shall conform to a carbon equivalent (CE) of 0.50 maximum as determined by the following formula:

CE = %C + %Mn/6 + (%Cr + %Mo + %V)/5 + (%Ni + %Cu)/15 . A lower Carbon equivalent ration maximum may be agreed upon between the purchaser and the producer. S5.3 The Carbon equivalent ration shall be reported on the MILL test report.

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.

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.

Equivalent Material

Some key features of ASTM A106/ ASME SA106 seamless Pressure pipe include:

High Temperature Service: ASTM A106 tubes are specifically designed to withstand high temperatures and pressure. They are commonly used in industries such as oil and gas, power generation, and petrochemical.

Seamless Construction: ASTM A106 tubes are manufactured without any welded seams. This ensures better strength, reliability, and uniformity throughout the tube's length.

Chemical Composition: ASTM A106 tubes are made from carbon steel, which provides superior mechanical properties and excellent resistance to corrosion.

Mechanical Properties: The mechanical properties of ASTM A106 tubes vary depending on the grade. Grade A tubes have a minimum tensile strength of 48,000 psi (330 MPa) and minimum yield strength of 30,000 psi (205 MPa).

Grade B tubes have a minimum tensile strength of 60,000 psi (415 MPa) and minimum yield strength of 35,000 psi (240 MPa).

Grade C tubes have a minimum tensile strength of 70,000 psi (485 MPa) and minimum yield strength of 40,000 psi (275 MPa).

Testing: ASTM A106 tubes undergo various tests to ensure their quality and performance. These tests include hydrostatic or nondestructive electric tests, mechanical tests (tensile, flattening, and bending), and chemical composition analysis.

Applications: ASTM A106 tubes are commonly used for transporting fluids and gases at high temperatures and pressures. They can be used in boiler systems, heat exchangers, power plants, refineries, and other high-temperature applications.

It's important to note that ASTM A106 is not interchangeable with other ASTM standards, such as ASTM A53 or ASTM A333, as they have different specifications and applications. It's crucial to consult the specific requirements of your application and verify compatibility with ASTM A106 tubes.
