S tainless S teel T ubing: M anufacturing & M achinery I f there is such a thing as a basic tube, it would be made of stainless steel. However, as a glance at a few tubemakers’ websites will attest, the casual designation is not so easily defended. Typically, a company will group its product list under simple headings: welded and drawn, seamless drawn, As-welded. But from that point on the word ‘basic’ loses meaning. The number and variety of products on offer – like the number and variety of their applications – are impressive, even overwhelming. Fortunately, the number and variety of experts in the design and operation of the machinery and peripheral equipment of stainless tube manufacture are more than a match for the heavy demands put on them. The companies reviewed in this section of Tube & Pipe Technology know that each grade of stainless steel tubing is unique – in marked contrast to the uniform conditions of the tubemaker’s outside world. Here, every competitor is keen, the lead times are all short, the standards to be met are tougher almost by the day, profitability is paramount.
