4). The curved shell will offer more of a challenge. The examiner will certainly need to establish if the certification holder is referencing the bevel from the vertical axis of the nozzle (Fig. 5) or from the variable reference plane of the bent covering (Fig. 6). When bevels are prepared with a reducing torch and also completed with a mill, it is extremely challenging to preserve an exact angle.

Inspectors are educated to think only what their eyes tell them; yet when the examiner can not see the internal surface area of the tube, it becomes tough to approve that situation.

One "warning" to a prospective problem would be if the inspector observes that the tube ends have actually not been beveled. The inspector ought to promptly ask the certificate holder about this scenario.
