In the past several years there have been significant changes to the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (B&PV) Code and the use of international pressure vessel codes such as EN 13445. There is also been a trend to using higher strength materials for vessel construction. This has lead to thinner and more flexible vessels. This paper discusses some of the potential unintended consequences of these vessels related to non-pressure loads, the need to be aware of these loads, and necessity to properly specify the design criteria to the fabricators in order to achieve the desired results.
