What Is A106 Grade B Pipe?

A106 Grade B Pipe is a seamless carbon steel pipe manufactured according to ASTM A106/A106M requirements for high-temperature service.

It is commonly used for transporting:

  • Steam
  • Water
  • Oil
  • Gas
  • Process fluids
  • Hydrocarbon fluids
  • Other industrial media

ASTM A106 is a pipe product specification, while Grade B identifies the material grade within that specification.

The common designations include:

  • A106 Grade B Pipe
  • ASTM A106 Grade B Pipe
  • A106 Gr B Pipe
  • A106 Gr B
  • A106B Pipe
  • ASTM A106B
  • A106 Grade B Seamless Pipe

Key Properties of A106 Grade B Pipe

A106 Grade B provides a combination of mechanical strength, weldability, and suitability for elevated-temperature service.

Important characteristics include:

  • Seamless construction
  • Good strength
  • Good weldability with appropriate procedures
  • Suitable for high-temperature service
  • Good machinability and fabrication characteristics
  • Widely used in industrial process piping
  • Available in a broad range of pipe sizes and wall thicknesses

Actual performance depends on the grade, dimensions, temperature, pressure, service medium, and applicable design code.

A106 Grade B Mechanical Properties

Mechanical properties are an important consideration when selecting A106 Grade B Pipe.

Typical requirements cover:

  • Tensile strength
  • Yield strength
  • Elongation
  • Bend or other specified mechanical testing

Actual minimum values and testing requirements should be verified against the applicable ASTM specification and product condition.

A106 Grade B Seamless Pipe

A106 Grade B Seamless Pipe is manufactured without a longitudinal welded seam.

The seamless construction and material specification make it widely used in process and high-temperature piping applications.

Typical applications include:

  • Steam piping
  • Boiler-related piping
  • Refineries
  • Petrochemical plants
  • Power-generation facilities
  • Process plants
  • Oil and gas facilities
  • High-temperature fluid transportation

The required pipe size, wall thickness, temperature, pressure, and applicable piping code should be evaluated before selection.
