 Minimum design metal temperature

The Minimum Design Metal Temperature (MDMT) is a crucial parameter in the engineering and design of pressure vessels and piping systems. It refers to the lowest temperature at which the material of the vessel or piping can safely operate without risking failure, such as brittle fracture or other forms of material degradation. MDMT is important for several reasons: 1. **Material Properties**: The mechanical properties of materials, especially metals, can change significantly at lower temperatures.
