Calculation of structural minimum thickness of pipe

[sumon emam]

As per section 11.1.3 of API 574:

"In low-pressure and low-temperature applications, the required pipe thicknesses determined by the Barlow formula can be so small that the pipe would have insufficient structural strength. For this reason, an absolute minimum thickness to prevent sag, buckling, and collapse at supports should be determined by the user for each size of pipe."

Table 6 (attached ) of the same code provides some data for Carbon and Low-alloy Steel Pipe at less than 205 degree centigrade condition.

My question is how this strength is measured and in case of temperature higher than 205 degree centigrade what are the values.
