force had a little effect on the peak moment but changed the deformation pattern and state of critical compressive strain of linepipe. It was found that the developed X80 linepipe was within the specification of DNV and API codes in terms of buckling capacity. In case of X100 steel, bainitic ferrite exhibiting lath and granular type morphology was major phase and M/A existed as second phase. It was shown that the developed X100 steel can be realized to have appropriate properties for UOE pipe. DWTT 85% SATT of the tested 19mm thick X00 steel pipe was below -40 oC.
