Why cbd is used to depressurized after hydraulic test in boiler?

CBD, or Chemical Boiler Draining, is used to depressurize a boiler after a hydraulic test to safely remove excess pressure and ensure the system is secure for further operations. This process helps in identifying any potential leaks or weaknesses in the boiler's structure. By utilizing CBD, operators can efficiently and safely drain water and contaminants from the system while minimizing the risk of damage or accidents. Ultimately, it prepares the boiler for maintenance or re-commissioning.
