The minimum wall thickness required for equipment to safely withstand its design or operating conditions.
Minimum Required Thickness is the minimum wall thickness necessary for a pressure-retaining component to safely resist the specified pressure, mechanical loads and applicable design conditions in accordance with the governing engineering code. It is commonly used during inspection and fitness-for-service assessments to determine whether equipment remains suitable for continued operation.
Minimum Required Thickness defines the lowest acceptable wall thickness for the safe operation of pressure equipment.
Remaining wall thickness is routinely compared with the Minimum Required Thickness during inspections to evaluate corrosion, erosion, remaining life and continued fitness for service.
Minimum Required Thickness defines the minimum acceptable wall thickness for safe operation, whereas actual measured thickness reflects the current physical condition of the equipment.
