What process uses water pressure to test the integrity of a boiler?

The process that employs water pressure to test the integrity of a boiler is known as hydrostatic testing. This method involves filling the boiler with water and then pressurizing it to check for leaks and ensure the structural integrity of the boiler under pressure. It is essential in confirming that the boiler can safely handle the operational pressures it will encounter during use.

Hydrostatic testing is a critical procedure, as it helps identify potential weaknesses in the materials and construction of the boiler, which can be vital for safety and operational efficiency. By using water, the method can safely amplify the pressure beyond normal operational levels to detect any flaws without the risks posed by using more hazardous substances.

In contrast, pneumatic testing involves air or gas pressure to test systems, thermal testing assesses the temperature equipment can withstand, and electrical testing checks the electrical components of a system. Each of these methods serves different purposes and does not substitute for the comprehensive assessment provided by hydrostatic testing when it comes to boilers.
