Thermal energy losses from heat unit; square units, cylinder units and discarded hot water in one of dairy production plant at 10th of Ramadan City were 1207.40, 105.66, 343.28 and 977.99 MJ/h, respectively. The thermal energy losses from steam pipes and exhausted pipes were 897.86 MJ/h and 239.09 MJ/h, respectively. The percent of thermal energy losses from horizontal steam pipes represents a percentage of 93.37% while vertical steam pipes thermal energy losses represents 6.63% of total thermal energy losses from plant steam pipes, respectively. The percentage of horizontal steam pipes, vertical steam pipes and total steam pipes insulated formed about 96.77%, 51.83% and 93.78% from total horizontal, vertical and total plant steam pipes, respectively. The percent of thermal energy saving due to insulated the steam pipes by using three different insulation materials were compressed fiberglass covered with aluminum slab with a thickness of 2 inches , commercial fiberglass covered with aluminum foil with a thickness of 2 inches and commercial fiberglass covered with aluminum foil with a thickness of l inch saving 87.07%, 78.92% and 76.96%, respectively, while insulated the exhausted pipes by compressed fiberglass covered with aluminum slab with a thickness 2 inches saving 94.21%
