ASTM A106 Hot Rolled Seamless Steel Pipe

ASTM A106 Hot Rolled Seamless Steel Pipe
ASTM A106 seamless steel pipe pertains to the American standard steel pipe. A106 encompasses A106-A and A106-B. The former is equivalent to the domestic 10# material, while the latter is equivalent to the domestic 20# material. It belongs to the ordinary carbon steel series and is one of the commonly utilized materials. ASTM A106 seamless steel pipe incorporates both cold drawn and hot rolled processes. Apart from the distinct production processes, the two differ in precision, surface quality, minimum size, mechanical properties, and organizational structure. It is widely employed in petroleum, chemical, boiler, power station, shipbuilding, machinery manufacturing, automotive, aviation, aerospace, energy, geology, construction, and military industries, among others.

ASTM A106 Seamless steel pipe pressure resistance calculation method

S is selected as S=8; For seamless steel pipe with P less than 17.5MPa, S is the safety factor of the seamless steel pipe, the wall thickness is 3mm,

The pressure that the pipe can withstand P=(2*σ/S*δ)/D

Where: The expected pressure to weaken is P, the wall thickness is δ, and what is the maximum pressure of the seamless steel pipe?

Set the tensile strength of the material as σ, Zhan Huorong is aware of the outer diameter of the pipe D;

The pipe wall thickness δ=(P*D)/(2*σ/S)

Where S is the safety factor;

Since P is less than 7MPa, Zhan has learned that S is S=4;

Let's select a safety factor of S=6; Select 20 steel with a tensile strength of 410MPa in the steel market, and the outer diameter of the pipe D
