ASTM A106 carbon seamless steel pipe introduction
ASTM A106 seamless steel pipe belongs to American standard steel pipe, A106 includes A106-A, A106-B. The former is equivalent to the domestic 10# material, while the latter is equivalent to the domestic 20# material. Belongs to ordinary carbon steel series, is one of the commonly used materials. ASTM A106 Seamless steel tubes include both cold drawing and hot rolling processes. In addition to the production process, the two are different in accuracy, surface quality, minimum size, mechanical properties, organizational structure. It is widely used in petroleum, chemical industry, boiler, power station, ship, machinery manufacturing, automobile, aviation, aerospace, energy, geology, construction and military industry and other industries.
ASTM A106 carbon seamless steel pipe pressure on the calculation
ASTM A106 Pressure Calculation method for Seamless Steel Tubes
S choose S = 8; P is less than 17.5mpa seamless steel pipe, S is safety coefficient seamless steel pipe, wall thickness is 3mm,
Pressure P= (2*σ/S*δ) /D
Where: pressure P is expected to weaken, wall thickness is δ, what is the maximum pressure of seamless steel tube?
Given that the tensile strength of the material is σ, Zhan Qiurong learned that the outer diameter of the pipe is D;
Pipe wall thickness δ= (P*D)/(2*σ/S)
Where S is the safety factor;
Because P is less than 7MPa, zhan Qiurong learned that S chooses S=4;
Let's say the safety factor is S=6; 20 steel tensile strength 410MPa steel market, pipe diameter D
