Handbook for heating and ventilating engineers . lt;When steam is admitted to a coldpipe, or to a pipe that is full of water, it is suddenly con-densed and causes a sharp craclcing noise. The concussionproduced by this condensation may become so severe as tocrack the fittings and open up the joints. The noise is due toa sudden rush of water in an endeavor to fill the vacuumproduced by the condensed steam. Steam at atmosphericpressure occupies 1644 times the volume of the water thatformed it, hence, by suddenly condensing- it, a very highvacuum may be produced. This action causes a relativelyhigh velocity in any body of water adjacent to it. Theworst condition is found when a quantity of steam entersa pipe filled with water. Condensation suddenly takes placeand the two bodies of water come together with high ve-locity causing severe concussion. Steam should always beadmitted to a cold pipe, or to one filled with water, veryslowly. 90. Returning tbe Water of Condensation, In a LotvPressure Steam Heating System, to the Boiler;—In re-.
