API 560 specifies allowable nozzle loads and moments for tubes and manifold.
Does anyone help me to understand about the basis on how these values are derived ?
I am not working on a heater but have similar equipment where a high pressure (approx. 70 bar) manifold having a coil is welded to low pressure casing plate (20 kpa) and want to establish a general rule for defining a basis for allowable nozzle loads and moment for such construction.
