(ii) such pipe exceeds two hundred fifty-four millimeters in internal diameter and the pressure of steam exceeds one kilogram per square centimeters above the atmospheric pressure,

and includes in either case, any connected fitting of a steam-pipe and feed-pipe;

(s) "structural alteration, addition or renewal" means,---
