P roduction of H eat T ransfer T ubing

H eat transfer tubing is more closely associated with equipment in general use than many – perhaps most – other categories of tube. And because much of that equipment sees service in the very narrow zone within which we are able to alter our personal environment, it may prompt the occasional reflection on the phenomenon of heat exchange and its exploitation for domestic purposes.

An air conditioner in a heat wave; a boiler in a cold snap; for the period of the emergency these might excel even the plumbing system in the regard of the household. Appreciation for the marvel of heat transfer tubing is well warranted. This is a product designed and fabricated to function not in one, but in two and, in many instances, three distinct environments simultaneously. The simple terms ID and OD, designating inside and outside diameters, take on new meaning when the inside is frigid, the outside torrid, and the tube itself – perhaps coiled tight for maximum utilisation of space – is packed into an enclosure which may present heat-transfer issues of its own.

The comforts secured by heat transfer tubing may be enjoyed by the layman and tubing professional alike. Only one of them will know how they have been achieved. As with all the best magic, that is exactly as it should be.
