Energoflex Super Protect Pipe Insulation 28/6 mm, Red, Polyethylene Foam, Art. EFXT028062SUPRK

Read them from left to right: 28 mm is the inner diameter of the insulation and thus the outside diameter of the pipe, 6 mm is the thickness of the foam, and 2 m is the length of one tube. The colour is not in this part of the name but in the article code, where SUPRK stands for red.

For the joints you need Energopro contact adhesive and reinforced self-adhesive Energopro tape in red, because the maker's guide glues the butt ends of neighbouring tubes and then tapes over the joint. Energoflex lists both as separate accessories, so they are not included with this 28 mm insulation.

Yes, up to the limit the maker gives: the maximum working temperature of Super Protect is +95 °C. Energoflex developed these tubes for heating and water-supply pipes inside floor and wall constructions, and the foam layer compensates for the thermal expansion of the pipe.
