Cracks in pressure vessels at the vapor-liquid interface
Thread Content
In pressure vessels where saturated water and steam coexist, cracks are prone to form at the vapor-liquid interface, especially at the weld areas. Please analyze this and provide your opinions.
The rupture of steam bubbles leads to cavitation; the gas-liquid interface is also prone to the accumulation of corrosive elements, and a potential difference forms at this interface. The interaction of these various factors results in interfacial corrosion
Pay attention to the post; more learning is still needed in terms of hands-on operations* – let’s see if there are any great answers.
Are the pressures on both sides of the interface different? Vaporization at the interface? High-temperature corrosion, electrochemical corrosion.
