Copper tube for sanitary and heating applications

Durable product • Q-tec® offers the same long life as all copper tubes • he inner pipe is made of copper and thus offers copper’s well-proven T benefits for sanitary and heating applications • The use of copper ensures that Q-tec® is 100% diffusion tight High pressure resistance Thanks to the strength of the copper tube, Q-tec® is suitable for operating pressures of more than 30 bar (14 x 2, 16 x 2, 20 x 2) Low thermal expansion Q-tec®, like other copper tubes, shows a relatively small increase in length as a result of thermal expansion Easy to use Q-tec® is easy to bend, easy to cut and...

Typical applications Q-tec® • drinking water (cold and hot) • floor heating • cooling/heating of building components • ground collectors • cooling systems 2 drinking water (hot) drinking water (cold) heating systems cooling systems gas liquefied gas oil KME Germany GmbH & Co. KG — Q-tec®

Laying Q-tec® tube Q-tec® can be laid on any suitable under-floor insulation available commercially or as part of a system. The coil is rolled out with the help of positioning foil on flat surfaces or on profiled plates. Material needed: positioning foil, profiled plates Bending The tube can be bent easily by hand. A tighter radius can be achieved using a bending tool or bending spring. Tools: bending tool or bending spring, as required Cutting to length, rounding, expanding and deburring The tube is cut to length using a Q-tec® tube cutter. Any burr is removed using the deburring tool,...
