scope:

The following directive specifies the design and construction of welded joints in tanks, apparatus and pipelines. It supplements the existing standards relating to this equipment.

The rules are based on an evaluation of many years of experience. The examples cannot replace the necessary design calculations for construction. This applies particularly to deviations from the welding principles specified in section B.

The dimensions of individual components (wall thicknesses, diameters etc.) are to be taken from the specification sheets for the various tank forms.
