As will be noticed from the sections in Figs. 12 and 13, thecopper pipe which in continental practice is much in use and istoday used exclusively in the boiler feed line, is equipped withbronze flanges. The upper right-hand section in Fig. 13 shows aparticularly interesting construction employed by the Sulzcr where it becomes necessary to cut the pipe length in the fieldand make up the joint; this type of construction is often used asa filling-in piece or distance piece between the engine and pipe, as e -Size, IMange Thick- Ml.

This table is abridged from tables ofstandard high pressure pipe fittings in which all the dimensions wereoriginally given in the metric system, and in-the subsequent reduc-tion to inches and fractions of an inch, the resulting figures havebeen slightly increased. There are numerous types of gaskets inuse in high pressure steam lines, those w
