the subject, wrought-iron riveted boilers constructed from plates only 3 ft. by 1 ft. were in use at that time, working at pressures up to qo lb.fsq. in. A present-day tendency is for electrically welded seams to take the place of riveting, especially for the internal parts of tank-type boilers, where such parts are in compression.
In my experience, the most satisfactory construction is all bronze-welded seams, and silver-soldered flues. Thinner metal can be used, with a greater factor of safety, than if the joints are riveted and sweated.

Boilers that operate higher than 15 psig are called "high-pressure" boilers. A hot water boiler, strictly speaking, is not a boiler. It is a fuel-fired hot water heater. Because of its similarities in many ways to a steam boiler, the term ''hot water boiler'' is used. Hotwater boilers that have temperatures above 250° Fahrenheit or pressures higher than 160 psig are called ''high temperature hot water boilers''.
For welded construction, the ASME Boiler and Pressure Vessel Code limits the carbon content to less than 0.35%. Thus, virtually all of the materials used in the construction and repair of pressure parts of boilers fall into this classification.
