Descaling through acoustic resonance and underwater shockwave
Acoustic Resonance descaling Applying pressure wave into enclosure empty vessel causes vibration on its body surface. When wave generator frequency is equivalent to vessel natural frequency, the body surface can violently sway and oscillation become stronger and stronger as the system gains more energy. This high energy oscillation can be controlled in a safe manner to cracks and remove scales. Underwater Shockwave Descaling
