Insert precision-integrated into a blank body by additive manufacturing

A steel pipe for drilling, operating hydrocarbon wells, transporting oil and gas, carbon capture or geothermal energy, the steel pipe comprising:

• at least one male or female insert and a metal body, said insert comprising at least a first thread axis, at least one toric or frustoconical sealing surface, a threaded part and a non-threaded part connected to the metal body, wherein the metal body has been produced entirely by additive manufacturing, and in that a minimum and radial thickness of an insert is determined according to the following equation:
• min thickness=Rext−(K*Epg+Ri)
• wherein min thickness is a minimum value of the thickness of an insert in mm, Rext is a value of an outside radius, Epg is a value of a thickness of a root of a thread tooth, Ri is a value of an inside radius, and K is a value of a minimum thickness ratio and is between 0.25 and 0.7.
