EN 12953 Shell boilers
EN 12953 Shell boilers
(OP)
Please could somebody advise.
How different is EN 12953 from its TRD predessor with regard to basic details such as wall thickness and nozzle reinforcement for a 230 psig boiler? I get very much more conservative results applying EN 12953 to an existing TRD design. ( >10% ) This surprises me. I was expecting basic details to be similar.
