In which DIN EN Standart i can find allowable safety distances from the buildings???

Thank you LittleInch. I will try to ask them like you sad.

yes but i dont have that standart and the factory sad according EN 10217-1 is not mandatory for each pipe......Sory for my igniorance brother

hi! The Standard is EN10217-1

Please if someone can inform me about Hydro test frequency and if it is mandatory for each pipe according to this standart???

lol API 5L X60M is an USA standart of material so to be tested with ASME and from EN we took the loads to calculate knowing that EN and ASME have their equivalent grades of steel. but my answer was which tests are mandatory for each pipe length acording ASME. Anyway thank you.

our design code used are from EN and pipe standart is API 5L X60M. But as Testing procedures we required to be acording ASME...

HYDROTEST,CHARPY and other TESTS, Are these tests mandatory [highlight #EF2929]for each pipe length[/highlight] acording to ASME ?????

Thanks you weldstan. I understand but should the manufacturer do the charpy test and chemical test to prove the material required for the pipes ? And where can i find any material to guide me for the specifications of these tests? Thanks. Best regards.

I was reading the standard ASME B31.1-2010 Power Piping, In this standard are mostly mentioned the testing about welds,Hydro static Testing and pneumatic testing. I am interested to know if are other testing methods like charpy test that are necessary. I mean for fabrication production...

So it is ok. Thanks for your answers mate.

Thank you stanweld. How you think for E6010 for root pass) and E7018 for filler passes?

Which are the best electrodes to weld these grades of steel pipes ???? Pipe welding of S355j2(+ N) with api 5L x60 ?

which is the solution while exporting from tekla to DWG to keep dimensions like autocad dimensions not as diveded lines...

The process is SMAW cellulosic electrodes. I decited for the root pass BOHLER FOX CEL and other passes BOHLER FOX CEL 85. Thanks for yor reply mate..

Can anyone suggest me the best electrodes of bohler welding for pipeline with steel X60?

Thanks mates. I am trying to take into consideration any potential problem that may occur during the work process. Because of my Inexperience in the pipelines i am trying to clear my doubts about this work. Anyway i have found some information that the pipes in most cases are checked and...

Thanks for your reply but your answer didn't helped me mate. Is the first time that we are working for a pipeline. I am just trying to get any helpful answer anyway thanks for your time.

Does the demagnetization process should be performed by the manufacturer of the steel pipes? Is this process important for the welding procedure or the welds can be made without passing this procedure. BEST REGARDS...

Ok i will offer them only the lunch and dinner so they will be happy :-)[afro]
