2. 3. 4. 5. Saturated steam Dry steam Wet steam Superheated steam Highly superheated or gaseous steam Three of these classes of steam (wet, saturated, and superheated) are shown in the illustration of a safety valve blowing in Figure 2-10. It should be pointed out that neither saturated steam nor superheated steam can be seen by the naked eye. Saturated steam may be defined as steam of a temperature due to its pressure. Steam containing intermingled moisture, mist, or spray is referred to as wet steam.

Temperature at which a liquid begins to boil (Figure 2-12), and it depends upon both the pressure and the nature of the liquid. 7 psi. The relationship between boiling point and pressure is such that there is a definite temperature or boiling point corresponding to each value of pressure. When vaporization occurs in a closed vessel and there is a temperature rise, the pressure will rise until the equilibrium between temperature and pressure is reestablished. One’s knowledge of the fundamentals of steam heating should also include an understanding of the role that condensation plays.

Pipe fitters, plumbers, steam fitters, and sheet-metal workers may occasionally do some work with heating, ventilating, and air conditioning equipment. Both pipe fitters and plumbers (especially the former) are frequently called upon to assemble and install pipes and pipe systems that carry the heating or cooling conveying medium from the source. Both are also involved in repair work, and some pipe fitters can install heating and air conditioning units. Steam fitters can assemble and install hot-water or steam heating systems.
