ASTM A106 GR B
ASTM A106 seamless steel pipe is a seamless steel pipe belonging to the American Standard, and the material is ordinary carbon steel series.

Product description
ASTM A106 seamless steel pipe belongs to American standard steel pipe. A106 includes A106-A and A106-B. The former is equivalent to domestic 10# material, and the latter is equivalent to domestic 20# material. It belongs to the ordinary carbon steel series and is one of the commonly used materials. ASTM A106 seamless steel pipe includes two processes: cold drawn and hot rolled. In addition to the different production processes, the two are different in accuracy, surface quality, minimum size, mechanical properties, and organizational structure. It is widely used in various industries such as petroleum, chemical industry, boiler, power station, shipbuilding, machinery manufacturing, automobile, aviation, aerospace, energy, geology, construction and military industry.

Pressure calculation
ASTM A106 seamless steel pipe pressure calculation method
S select S=8; P is less than 17.5MPa seamless steel pipe, S is the safety factor seamless steel pipe, the wall thickness is 3mm,
The pressure that the pipe can bear P=(2*σ/S*δ)/D
Among them: the pressure is the expected weakening of P, the wall thickness is δ, what is the maximum pressure of the seamless steel pipe?
Suppose the tensile strength of the material is σ, Zhan Rangrong learned the outer diameter of the pipe D;
Pipe wall thickness δ=(P*D)/(2*σ/S)
Where S is the safety factor;
Because P is less than 7MPa, Zhan Rangrong learned that S chooses S=4;
We choose the safety factor as S=6; choose 20 steel with a tensile strength of 410MPa for the steel market, and the outer diameter of the pipe D.
