steel x70 derating

API 5L X70 Pipe Specifications Octalsteel

API 5L X70 steel pipe has a minimum yield strength of 70,300 psi or 485 Mpa. The current X70 steel pipe are all controlled micro alloyed carbon manganese steels. The micro alloys elements are mainly Nb, V and Ti, and the total content of micro alloys does not exceed 0.15%. Therefore, the structure of the pipe is composed of acicular ferrite and Grade X70 an overview ScienceDirect TopicsAt the time, X70 grade steel pipes with diameters as large as 48" with 0.461" wall thickness were being used. The industry chose to wrap the steel pipes with isopolyester resinglass fiber composite.
