Abstract

Indian, shipping is growing rapidly but Indian shipyards are not able to deliver even a fraction of the tonnage being added annually. Extraordinarily long building period due to poor productivity in Indian Shipyards has been attributed to be the cause of this paradoxical state.

Hull fabrication takes up major part of building effort for the types of ships in vogue to-day. Welding, playing an important role inactivity of hull fabrication, has been discussed in the present paper and recommendations made for improvement of welding productivity in Indian Shipyards.

Abstract

PFBR is a liquid sodium cooled pool type fast breeder reactor. Reheater, a part of the steam generating system, is a vertical shell and tube type heat exchanger. The main construction material is 9 Cr - 1 Mo steel 85 no. tubes of 31.8mm O.D. and 2mm thickness are butt welded to tube sheet spigots at both the ends. These joints call for the highest level of integrity and reliability because of the possibility of potential interaction between sodium and steam.
