API 5CT J55 pipe manufacturing process:
Tubing made to API specs utilizes electric-weld or seamless procedures. Due to the fact that of the nature of the manufacturing, the cross section of the tubing wall location may be a little eccentric and the tubing slightly oval and not completely straight.

Electric-welded pipe has one longitudinal joint formed by electric-resistance or electric-induction welding without the addition of filler metal. The edges to be welded are pushed together mechanically, and the heat for welding is generated by the resistance to circulation of electric existing.

Both electric-weld and seamless procedures are appropriate for the majority of oil and gas services, but some choose seamless tubulars for sour service due to the fact that the electric-weld procedure might lead to a slightly different grain structure near the weld. Such differences are typically eliminated if the electric-weld tubing is heat-treated by the quenched-and-tempered process, which is necessary for API grades L80, P110, c90, and t95. Couplings usually are made from seamless tubular product of the same grade and type as the pipe.
