RAIL CAR HEATING AND TANK CAR HEATING is a necessary task for unloading for many different companies for many different fluids. This is a year round problem as many liquids need to be heated to a high temperature to be able to efficiently unload them, such as oil, corn syrup, molasses, etc. As the temperature gets colder, a wider range of liquids and chemicals are affected and need to be heated up as well to unload. I recently found an article that does a good job of explaining the proper procedure for heating up liquid caustic soda. Caustic soda needs to be heated for unloading purposes once it drops to 65°F or below.
The recommended method for heating these railcars is by using a low pressure steam generator. The coils and jackets on railcars are generally not designed to handle a higher pressure than 15 psi. High pressure steam is when the pressure is above 15 psi, anything below is considered low pressure. Steam powered locomotives ran at pressures well above 200 psi. Since the steam locomotive era, now moving into modern times, many rail cars use of low pressure steam generators. Not always is it economical for the industry to invest in costly rail car heating systems, this is where Pipevision and FAST Pipe collaborate at helping you out with your rail car heating services.
