PRECISION, which informs every aspect of tube making, does not take on greater urgency at the cutting station. And yet there is a sense in which it does. This is the point toward which the effort has been directed. It is here that the process yields a saleable product. It is also the point at which the transformation from work- piece to artefact could run into trouble. A tube that is not cut perfectly is not a tube that can be sold. Strictly speaking, it is not a tube at all, but a piece of very elegant scrap — essentially

of interest only to a scrap dealer. That this is a virtually negligible worry in our industry is due in no small part to the equipment and services available from companies such as those reviewed in this section of Tube & Pipe Technology. From pipettes to oil pipes, from soft copper to PVC — the specifics of a given

cutting job are, to cutting professionals, factors with which they have an easy familiarity. They are also elements of a precision-oriented speciality that demands mastery as great as any in the entire field of tube making.  Flexible and mobile plasma cutting of up to 50mm material thickness from Kjellberg
