Are standard pipe flanges that carry nozzle loads exempt from calculations?
Thread Content
I would like to ask a question: when the nozzle of the pressure vessel bears the load of the pipe, can the pipe flange used for flange connection be exempted from calculation?
According to current design codes, pipe flanges used for flange connections need to be calculated when calculating the load of the pressure vessel. This is because the pipe flange, as a connecting component, bears a certain amount of force and torque when transmitting loads, and its impact on the pressure vessel needs to be considered. Therefore, when designing a pressure vessel, proper calculation and selection of the pipe flange is required to ensure that it can safely withstand the load of the pipe. .
Any connecting flange will bear external loads, which may be large or small. If the external load is not known, it can be selected according to petrochemical standards.
Calculate the equivalent pressure according to HG/T20582
According to the regulations, strong installation is not allowed in pipeline installation. In this way, under normal circumstances, the pipeline force is not taken into account. If there are special circumstances where a large pipeline force will be transmitted to the flange, then it must be calculated according to this standard when selecting the flange reasonably.
