ASTM A106 Gr B standard 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.
OD: 48mm-720 mm
WT: 4mm~58mm
Length: 6m-12m or as required
Application: Hydraulic system pipeline pipe, pipe for boiler project, construction structure, etc.
Supplementary Technology: Plain or threaded with socket or beveled with plastic caps, hydraulic testing, eddy current, Infrared test.
Surface: Bared or painted, galvanized or with oiled or client option.
A106 steel pipe includes 3 steel grades (Grade A, Grade B, Grade C) These pipes are suitable for welding, bending, flanging, and similar forming operations. Mechanical testing of the specimens shall include tensile, bending, flattening, hydrostatic and nondestructive electric tests. Among 3 steel grades, ASTM A106 grade B is one most commonly used steel grade.
ASTM A106 Grade A and Grade B are produced in wide sizes and states, A106 gr.b contains higher carbon and manganese contents, its maximum carbon content is 0.23%, it shall be permissible to furnish pipe with other dimensions (from SCH10, SCH20, SCH30 to SCH100, SCH120, SCH160).
