Understanding Boilers as Pressure Vessels

boiler and a pressure vessel

Introduction to Boilers and Pressure Vessels

A boiler, in its essence, is a vessel that heats water or any other type of fluid under controlled conditions. The heated or vaporized fluid exits the boiler for use in various processes or heating applications. But here’s the key question: Is a boiler a pressure vessel? Absolutely! Boilers operate under pressure to generate steam or hot water, fitting the definition of a pressure vessel. At Red River, we recognize the importance of these systems in your operations and are dedicated to providing the highest quality and safety in our boiler manufacturing.
