The intent of this report is to describe the development of a creep model for use in producing isochronous curves for grade 91. The basis for the other component of strain, the plasticity or “hot tensile” curve, has been described elsewhere. Values of creep strain are needed over a wide range of conditions. At some

The objective of this project was to perform thermal analysis of pipeline heating configurations, with the intention of creating guidelines for the sizing of heating bands. The analysis consisted of two phases. The initial phase served to calibrate and verify the modeling assumptions used for the thermal analysis via comparison with experimental measurements taken for

The primary driver for initial efforts in high temperature flange design came from improvements in the steam power generation industry that resulted in higher steam temperatures and pressures being used in the late 1920s and early 1930s. The initial work of Baumann [3] in 1930 looked at the creep of bolts and flange components of
