What Does Tube Body Mean?

A tube body refers to the full length of a drill pipe. A strong drill pipe is essential to a successful drilling project due to the various loads and stresses that are endured during drilling. There are three general manufacturing processes for drill pipes: one piece forged, inertia welded, and press fit and welded.

One piece forged tube bodies are made out of a single piece of material and then heated for the forge and upsetting process. They are one piece of material, including the threads and mid-body.

Inertia welded drill pipes are manufactured from three pieces of material: the mid-body and two threaded ends or tool joints. The welding process creates no melted material and is actually done by holding the mid-body tube stationary and spinning the threaded ends or tool joints. The ends are spun to a specified speed and then pressed together with a calculated weight.

Press fit and welded type pipes are also manufactured from three pieces of material. The pieces are pressed together and then mig welded.

All tube types then go through a final forging, heat treatment and other finishing processes to ensure the tube body is free of all defects.
