What is the main reason for conducting dimensional checks on pressure vessels?

Conducting dimensional checks on pressure vessels is primarily done to ensure that the vessels meet specified size and shape requirements. Accuracy in dimensions is critically important in pressure vessel design and manufacturing because it directly affects how well the vessel can perform its intended function, including its capacity to contain pressure and ensure safety.

If the dimensions are incorrect, it can lead to issues such as misalignment with connecting piping, inadequate strength to handle operational pressures, or failure to fit within structural confines, which could compromise overall safety and functionality. Hence, verifying that all dimensions align with engineering specifications is a fundamental responsibility in the quality control process for pressure vessels.
