ASTM A106 seamless steel pipe belonging to the American standard, A106 including A106-A, A106-B. The former is equivalent to the domestic material # 10, # 20 which is equivalent to the domestic materials. Belonging to the ordinary carbon steel series, it is one of the commonly used materials. ASTM A106 seamless steel pipe including cold drawn and hot-rolled two processes. In addition to different manufacturing processes, but both of the accuracy, surface quality, minimum size, mechanical properties, structure is different. Widely used in petroleum, chemical, boilers, power plants, ships, machinery manufacturing, automotive, aviation, aerospace, energy, geology, construction and military industries.
ASTM A106 seamless steel pipe under pressure calculation method
Selected from S S = 8; P less than 17.5MPa seamless steel pipe, the safety factor S for the seamless steel pipe, the wall thickness of 3mm,
The tube can withstand a pressure P = (2 * σ / S * δ) / D
Where: P is the pressure is expected to weaken, wall thickness δ, seamless steel pipe to withstand the maximum pressure is how much?
Let the material tensile strength σ, Zhan Rong Rang informed pipe diameter D;
Pipe wall thickness δ = (P * D) / (2 * σ / S)
Wherein S is a safety factor;
Because P less than 7MPa Rijindoujin, Zhan Rong Rang informed S elect S = 4;
We chose a safety factor of S = 6; 20 election steel tensile strength of 410MPa steel market, the pipe diameter D
