Stripper condenser tube-to-tubesheet welding for the urea process

摘要

There is a requirement to guarantee a high quality level of tube-to-tubesheet welding, carried out with high-pressure heat exchangers on urea production plants. For this purpose, it is necessary for the manufacturer to use special welding equipment. In general, it is necessary to use welding equipment specifically adapted to an application, backed up by a customised training period for the operators. To support the equipment and training, it is also advisable to operate an experimentation lab to draw up fault-free welding programs.
