ASTM A106 Gr.B carbon seamless steel pipe

Carbon Steel Pipes (A106 Gr B Pipes) are made by killing steel along with the first melting process being an electric furnace, basic oxygen, and open hearth and mixed with a single refining. They are given hot treatment using cold drawn pipe and steel cast in ingots is permissible.
Product introduction

Carbon Steel Pipes (A106 Gr B Pipes) is one of the most common products that are used in the
development of gas or oil refineries, petrochemical plants, ships, boilers and power plants. They
are used at the place where water or oil is stored and search for a narrow space to be flown smoothly.
Generally, they are the big need of industries all around the world. They are also used where the piping
should transport gases and fluid that absorb higher pressure and temperature levels. They are divided
into two grades, first is A, the last one is B, but surprisingly their uses and specifications are almost same.

The total thickness of these carbon steel pipes is from ¼ to 30” and they are also differentiated in schedules,
shapes, and designs even dimensions too. The wall thickness of them is out of XXH such as 4 to 24 OD, 3 walls
to 18 OD and 2 walls to 8 OD.

Carbon Steel Pipes (A106 Gr B Pipes) are made by killing steel along with the first melting process being an electric
furnace, basic oxygen, and open hearth and mixed with a single refining. They are given hot treatment using cold
drawn pipe and steel cast in ingots is permissible.
