Representing the highest level of SAVE Spa quality, laser-welding ensures these carbon steel pipes perfect welding. Subsequent internal/external vitreous enamel coating baked to 850°C provides exceptional resistance against corrosion by combustion condensate.
V2 test results specified by corrosion resistance Standard 1856-2 show that Plus 1.2 mm and Plus Light flue pipes have a significantly longer duration than normally painted 2 mm thick pipes that have not received internal vitreous enamel coating. They are perfectly resistant even to extreme situations such as soot-fire (a fire that occurs inside the pipe) without being damaged or modified.

In order to prevent the leakage of condensate, they must be fitted with the inlet facing downwards (see drawing). To do this, it may be necessary to use an F/F anti-condensate fitting to start with.
