Below is a list of High Pressure Boilers manufacturers from Washington, Pennsylvania. High pressure boilers are tanks or vessels that facilitate the transfer of heat from its source to water or steam while maintaining a high internal pressure. High temperatures in a sealed volume result in high pressure, which can be used to maximize efficiency and power. High pressure boilers have historically been misunderstood and therefore dangerous; there are multiple recorded instances of exploding industrial steam engines or locomotives resulting in death and injury.
