Product Description

ASTM A106 Gr.B Pipes

ASTM A106 Grade B Pipes are seamless carbon steel pipes that are widely used in various industries for high-temperature service.

ASTM A106 Grade B Pipes are made from carbon steel, with a maximum carbon content of 0.30%. ASTM A106 Grade B Pipes are commonly used in industries such as oil and gas, petrochemical, power generation, and more. They are suitable for conveying fluids and gases at high temperatures and pressures.

Size range(mm):

Out diameter: 10-324mm

Wall Tickness: 1-30mm

Length: 14000mm max

ASTM A106/A 106M Standard Covers Seamless Carbon Steel Pipe for high-temperature service in NPS 1/8 TO NPS 48 (DN6 to DN1200) inclusive, with nominal (average) wall thickness as given in ASME B 36.10M. It shall be permissible to furnish pipe having other dimensions provided such pipe complies with all other requirements of this specification. Pipe ordered under this specification shall be suitable for bending, flanging, and similar forming operations, and for welding. When the steel is to be welded, it is presupposed that a welding procedure suitable to the grade of steel and intended use or service will be utilized.

ASTM A106/A 106M covers both seamless hot-finished and cold-finished pipe in sizes up to and including NPS 1/8 TO NPS 48(DN6 to DN1200) outside diameter for round tubes with wall thicknesses as required.

Permissible Variations in Wall Thickness

The minimum wall thickness at any point shall not be more than 12.5% under the nominal wall thickness specified.

Flattening Tests

Although testing is not required, pipe shall be capable of meeting the flattening test requirements of supplementary requirement S3, if tested.

What is ASTM A106

A106 pipe is American standard material, including A, B, C three grades, the ingredients of A106 A is carbon and silicon, the tensile strength grade is 330 MPa. The ingredients of A106 B is carbon、manganese and silicon, the tensile strength grade is 415 MPa. The ingredients of A106 C is carbon, manganese and silicon components, the tensile strength grade is 485 MPa.

ASTM A106 seamless pressure pipes (also known as ASME SA106 pipes) are commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers and ships. These pipes must carry fluids that exhibit higher temperature and pressure levels and gas.

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.

FAQ

Q: What is the difference between pipe design material A106 and SA106?

A: There is no difference between pipe design material A106 and SA106, Because the 2013 edition of the ASME II material chapter has pointed out that SA106 is consistent with ASTM A106,In addition, SA106 is a grade of American ASME,And A106 is the grade of ASTM.

Q: What does the mark CD in the steel pipe SA106Gr.B standard mean?

A: CD means cold drawn,SA106 stipulates that pipes below DN40 can be hot-rolled or cold-drawn; pipes above DN50 are conventionally hot-rolled. When the manufacturer and the purchaser reach an agreement, cold-drawn manufacturing is allowed.

Q: What is the difference between ASME SA-106 and ASME SA-106M?

A: The difference between ASME SA-106 and ASME SA-106M is that if the size standard is imperial, use ASME SA-106, if the size standard is metric, use ASME SA-106M.
