Seeking advice on the calculation of test pressure
Thread Content
In pressure test calculations, the formula (taking hydraulics as an example) is 1.25【σ】/【σ】t, where 【σ】 represents the standard stress from material testing. Meanwhile, GB150 has stress below 20°. Ask if the two are the same. If it’s different, how can the standard stress be found?
In the formula for the pressure resistance test, t represents the allowable stress at the operating temperature, as well as the allowable stress at the temperature at which the pressure resistance test is conducted. Generally, the pressure resistance test is carried out at room temperature, in which case the allowable stress specified in GB150 for temperatures below 20°C can be used
Got it, thank you so much. :handshake
