Product Description

Seamless Carbon Steel Pipe

ASTM A106 seamless pressure pipe (also known as ASME SA106 pipe) is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit higher temperatures and pressure levels.

ASTM A106 pipe (also covered in ASME specifications as S/A 106) is the standard specification for seamless carbon Steel Pipe for high-temperature service. Most common uses are in refineries and plants when gasses or fluids are transported at high temperatures and pressures. Federal Steel Supply is a world leader in the supply of A106 / SA 106 pipe and stocks a full range of grades B/C in a size rage of NPS 1/8" to NPS 48", with nominal (average) wall thickness as given in ANSI B36.10. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification*. Pipe ordered under this specification shall be suitable for bending, for flanging, for welding, and for similar forming operations. A full range of A106 stock is available in Schedules 10 through 160, STD, XS, XXS. Unscheduled wall thicknesses available up to 4 inches.

Bangdong Pipeline Tubular Products ASTM/ASME A106/SA106 seamless carbon steel pipe is used in industrial applications involving high heat, including process piping, boiling plants, compression stations and refineries. The additional silicon boosts this product`s performance in high-temperature environments, such as steam lines and processing applications.

Bangdong Pipeline Products offers the widest variety of sizes available in the industry. All of our products are domestically sourced, developed, and produced, which means our customers have immediate access to exactly the products they need for their particular application. And, because our products are domestic, you are assured of the highest quality and manufacturing standards and a local, concerned, customer service presence.

A106 Comparative Specifications

ASTM Specification A106 covers seamless carbon steel nominal wall pipe for high-temperature service, suitable for bending,and similar forming operations. NPS 1-1/2 and under may be either hot finished or cold drawn. NPS 2 and larger shall be hot finished unless otherwise specified. Surface finish standards are outlined in the specification.

Purchaser may specify NDE in lieu of hydro-static test or neither. Unless otherwise specified, pipe is furnished with plain ends.

· Testing Requirements for seamless A106 carbon steel pipe

o 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 2,500 psi for NPS 3 and under, and 2,800 psi for the larger sizes. Pressure is maintained for no less than 5 seconds.

o Mechanical Tests:

§ Tensile Test: Either transverse or longitudinal are acceptable for NPS 8 and larger

§ Tensile tests smaller than NPS 8: Longitudinal testing only

§ Flattening Test: NPS 2 and larger

§ Bending Test (cold): NPS 2 and under

o Number of Tests: One tensile test per 200 lengths.

· Permissible Variations in Dimension

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

o Weights per foot: The weight of any individual length shall not vary more than 10% over and 3.5% under that specified. NOTE – NPS 4 and smaller are weighed in lots. Larger sizes are weighted by individual length.




1 ½ and smaller












Over 18



o Outside diameter: Shall not vary from standard specified below at any point.

· Lengths of A106 seamless carbon steel pipe
Lengths of Bangdong Pipeline Tubular Products A106 seamless carbon steel pipe must be specified on order. No [joiners" are permitted unless otherwise specified. If no definite lengths are required, the following practice applies:

o Single random – 16` – 22` (5% may be 12` – 16`)

o Double random – Minimum length is 22`. Minimum average is 35` (5% may be between 16` – 22`)

· Marking Requirements
Rolled, die stamped, or paint stenciled (manufacturer`s option).

o Manufacturer`s name, brand, or trademark

o A106 A, A106 B, or A106 C

o Hydro-static test pressure and/or NDE, or NH if neither is specified

o Size, length, weight per foot (NPS 4 and larger)

o ANSI schedule number or weight class or wall thickness

o Additional [S" if tested supplementary requirements
