ASTM A106 Grade B Carbon Steel Pipes Specifications

ASTM A106 Grade B Carbon Steel Pipes Standards

Material and Grades of ASTM A106 Grade B Carbon Steel Pipes

A106 Grade B is made from killed steel, which means it is deoxidised with at least 0.10% silicon. That gives a clean, uniform structure that holds up in hot service.

The standard allows manganese to rise above its normal limit when carbon is lower. For each 0.01% that carbon sits below 0.30%, manganese can go 0.06% above the stated maximum, up to 1.35%. This lets mills reach the required strength with a lower carbon content, which helps welding.

Hot finished pipe needs no final heat treatment. Cold drawn pipe is heat treated after the final draw, at 650°C or higher, to restore ductility. Many projects specify dual or triple certification, such as A106 Grade B with A53 Grade B and API 5L Grade B. This is possible where the chemistry and properties meet each standard, so tell us at enquiry.

ASTM A106 Grade B vs A53 Grade B vs API 5L Grade B: Which One Do You Need?

Choose A106 Grade B when the pipe is seamless and runs hot, as in steam, boiler and refinery lines. Choose A53 Grade B for general-purpose service where a welded pipe is acceptable. Choose API 5L Grade B for pipelines. Many buyers ask for dual certification so one pipe satisfies several of these standards at once.

ASTM A106 Grade B Carbon Steel Pipes Chemical Composition

The total of copper, nickel, chromium, molybdenum and vanadium must not exceed 1.00%.

ASTM A106 Grade B Carbon Steel Pipes Mechanical Properties

Pressure Capacity of ASTM A106 Grade B Carbon Steel Pipes

The table gives an indicative working pressure for common sizes, using Barlow's formula P = 2 × S × t ÷ D, with an allowable stress S of 138 MPa (20 ksi, as used in ASME B31.3 at ambient temperature). It uses the nominal wall and no corrosion allowance. Allowable stress falls as temperature rises, and mill tolerance and joint design also reduce capacity. Final design must follow ASME B31.3 or B31.1 for your service.

ASTM A106 Grade B Carbon Steel Pipes Size and Weight Chart

Theoretical weight is (OD − Wall) × Wall × 0.02466, giving kg per metre with dimensions in mm. Real weight varies slightly within mill tolerance.

ASTM A106 Grade B Carbon Steel Pipes Sizes, Dimensions and Schedules

Two pipes of the same nominal size can have very different walls, and the schedule is what tells them apart. Thicker walls carry more pressure but weigh more and cost more. Schedule numbers follow ASME B36.10M, and DN is the metric size for each NPS.

Under ASTM A530, outside diameter tolerance is ±0.4 mm up to 1½ inch, ±0.8 mm above 1½ and up to 4 inch, +1.6/−0.8 mm above 4 and up to 8 inch, and +2.4/−0.8 mm above 8 and up to 18 inch. Wall thickness is held to −12.5%. We supply single random and double random lengths, and cut and bevel to your drawing.
