A 6-inch insulated pipe carries steam from the steam generator to the tank cars. A 4-inch insulated condensate line carries steam condensate from the tank cars to the de-aerator tank. Steam and condensate connections are provided for 20 tank cars.
The steam pipe connection located at each tank car station has a 2-inch valve. A 20-foot flexible hose is connected between the valve and the tank car. The flexible hose carries steam to the tank car.
The condensate pipe located at each tank car station has a 1-inch shut-off valve. A 1-inch check valve, steam trap, drain valve, bleeder valve and a 20-foot flexible hose are connected between the shut-off valve and the tank car. The flexible hose carries condensate from the tank car to the condensate piping. The steam trap prevents steam from entering the condensate piping. The check valve allows one-way flow of the condensate to keep it from flowing back into the tank car after the steam has been shut off.
The condensate piping carries the condensate to a receiver tank located near the rail line. The condensate collects in the tank until a float in the tank activates a steam-operated pump, which returns the condensate to the de-aerator tank.
