1)Usually it is difficult to maintain the nozzle loads for heater terminal loadings withing API-560 limits as the permitted loads are very less.What is the optimum value upto which one can go without any serious concern on coil safety??
2) Is there any restriction on the permitted loading / nozzle displacements on the cross over nozzle Steam injection points for connecting piping??. API does not give specific reference of such points.
