It is foundnecessary in the colder weather to heat the oilin the main storage tank by means of a steamcoil; the steam pipe from the power house beingrun along beside the main suction piping, sothat the heat is maintained in the oil on its way to the oilpumps. The arrangement of piping is shown in the illustrations anddrawings. Chapman straightway double-seated gate valves and. MOTOR GENERATOR SETS, ROPE DRIVE, SWITCHBOARDS AND WIRING INMAIN POWER HOUSE Chapman flanges are used throughout. All fittings are ofspecial thickness, designed for 150 lbs. pressure. Long-radiusbends are used wherever possible for flexibility and to reducefriction.
