It has beenthe experience on the continent, where the use of high pressuresand high degrees of superheat have been used to such an extentthat it is difficult to find a plant constructed within the past fewyears where these features are lacking, that the higher the temper-ature of the steam the greater will be the resulting economy of theengine or turbine. The use of steam at high temperatures naturally means an in-crease in the expansion of the pipe lines and in the strains broughtupon them, and the use of high pressures demands solid and sub-stantial construction. There are a number of important conditionswhich nnist be met successfully by the piping system
