<p>The heatable pipeline has inner layer (2), an outer layer (3), and a heating element (4), where the inner layer has a higher thermal conductivity than the outer layer, within the operation temperature range of the heatable pipeline. The inner and outer layer has a polymeric material, particularly an elastomeric material, and has an ethylene propylene diene monomer material. The barrier layer has a polypropylene-ethylene propylene diene monomer-copolymer.</p> |
