Hot Isostatic Pressing of Large Bore, Stainless Steel Pipework for a Safety Critical Application

This paper presents an overview of the work undertaken by Rolls-Royce to introduce Hot Isostatically Pressed (HIP) large bore, austenitic stainless steel pipework into a safety critical application - a Nuclear Reactor plant. It describes the advantages of using HIP product forms to combine separate sections of straight pipe and elbows and, in so doing, reducing the number of structural plant welds.
