Friction saws are the conventional cutoff machines for tube and pipe mills. Drawbacks include hazards (noise and risk of breakage) and burrs they tend to generate. Tungsten-carbide-tipped (TCT) blades, which require more sophisticated sawing machines, run slower and safer, cut cleaner, and are less prone to breakage.

Most tube and pipe producers weld the seam as it is—without additives or fillers—and risk the problems associated with oxidation. A specially formulated brazing flux, in liquid or paste form, dissolves and removes oxides, prevents re-oxidation, and helps transfer weld heat to the seam.

High production threading of tube and pipe for use by the petroleum industry is accomplished using either mechanically actuated or digitally controlled, carbide tooled machines. The most effective way to deal with residual stress is to full body anneal each tube prior to machining; however, this may not be economically possible. One alternative is to limit the amount of energy that the tube is subjected to during machining. An examination of the cutting tools that are used to produce threaded product will reveal how the shape of the insert may affect the deformation of the tube.
