What Causes Boiler Tube Leaks | Boiler Tubes | ChemREADY

Reasons Why Boilers Leak: 1. Tube Corrosion. Corrosion and the breakdown of system components are the leading causes for boiler leaks. While this can theoretically happen anywhere within the boiler, corrosion in the tubes themselves is the most direct cause of leaks. Tubes can become corroded over time due to oxygen pitting.
