API 7-1Non-Magnetic Drill Collars for Bene EXERCITATIO
Drill torquati sunt densi-muri tubulosi e solido chalybe ex vectibus machinati et ad specificationes obviam et/vel API specificationum excedunt.Nostra experientia in materia specificatione, proprietatibus mechanicis, tractatione caloris, machinatione et inspectione in effectione producti reflectuntur.Drill monilia in lubricis et spiralibus designandis veniunt cum notis additis ad operationes liberas et tutas et molestas.
