Nov 14,2015·In the late 1970s and into the 1980s,X65 was considered more readily weldable; however,with todays filler metals and welding processes,I can see no reason to use X65 unless the costs are actually,somehow,lower.RE X65 (Gr.448) versus X70 (Gr.483) Line Pipe for Sweet Service,Liquid Transmission Lines. results for this questionWhat kind of steel is used in X70 pipe?What kind of steel is used in X70 pipe?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 bainite,and it generally has good welding performances.a.High strength b.API 5L X70 Pipe Specifications - Octalsteel results for this questionWhich is easier to weld,X65 or X70?Which is easier to weld,X65 or X70?Cost,availability,perceived to be easier to weld (especially manual welding),bigger margin between SMYS and UTS,but X70 is now being seen more and more.BTW,the grade descriptions are now 450 and 485 in the latest pipe codes.Also If you get a response it's polite to respond to it.X65 (Gr.448) versus X70 (Gr.483) Line Pipe for Sweet

Cost,availability,perceived to be easier to weld (especially manual welding),bigger margin between SMYS and UTS,but X70 is now being seen more1I know that the way the Canadian code reads,if you ever *did* see sour service,then you cannot use the Grade 483.I should check and see if theI was referring to api 5l/iso 3183.However I would imagine other codes will catch up eventually. Remember - More details = better answers AlsoAs far as I know,Canadians have been using API 5L X80 for quite a number of years. Is auzie5 in Canada,or Austria?I would suggest that auzie5 is in Australia where the project value considerations will still be the same as anywhere else in the world. Steve JoIn which case it might be a long way,in time and distance,for X70 pipe to travel.The question was compelling argument for X65 instead of X70.All depends on what you find compelling to be. We seem to have lost the OP thoughThe OP always goes away eventually.That's the idea.It's not so far from Japan,Korea and China.
