The height varies from3J to 9 feet, and the width from 3 feet to 7 feet in the standard are usually made up of 1-inch pipe, although lj-inch is commonlyused in the larger sizes. Fig. 136 shows another form; in this caseall the loops are made of practically the same length by the specialform of construction shown. This is claimed to prevent the short- 158 HEATING AND VENTILATION 149 circuiting of steam through the shorter loops, which causes the outerpipes to remain cold.
