and subtracting it from the burst load line,
the net pressure load at each depth
increment can be determined(Fig.21).

173 A designed factor is deemed necessary to allow for
wear, it is applied to the resultant burst load to
obtain the design line. It is applied and the design
line shown in Fig.22 is created.
Starting at either end of the design line, plot the
published values of burst strength for the least
expensive weight and grade of casing that exceeds
the design load. The section length is determine by
intersection with the design line. The strength of the
next applicable weight and/or grade can be plotted
to intersection, and this procedure repeated until the
string is completed designed for burst(Fig.23).
