According to the regulations of GB150, the calculation of opening reinforcement requires that the opening diameter be less than 0.5 times the inner diameter of the cylinder. Is this opening diameter d when calculating reinforcement? In addition, if it exceeds, is there a way to perform reinforcement calculation? Thank you. :handshake :handshake
According to the regulations of GB150, the calculation of opening reinforcement requires that the opening diameter be less than 0.5 times the inner diameter of the cylinder. This opening diameter refers to the sum of the inner diameter of the nozzle and the additional amount of 2 times the nozzle wall thickness, j d when calculating reinforcement.； If it exceeds the limit, it can be analyzed and calculated, or calculated with reference to HG20582. According to HG20582, there are restrictions, such as: Material yield-strength ratio requirements, fillet weld surface flaw detection requirements.
I agree that sometimes on the 2nd floor, if you are more careful, you can even include the corrosion allowance.
