Pipe Sizing Steam Supply andCondensateReturn Lines

sizing in a steam system: 1. The initial pressure at the boiler and the allowable pressure drop of the total system. The total pressure drop in the system should not exceed 20% of the total maximum pressure at the boiler. This includes all drops — line loss, elbows, valves, etc. Remember, pressure drops are a loss of energy. 2. Steam velocity.
