A multi-layered pipe comprising a wall having a polyolefin inner layer and a barrier layer being an outer layer relative to the polyolefin inner layer, the barrier layer being formed of a non-metallic barrier material, which barrier material has relative to polyolefin an enhanced resistance to permeation therethrough of hydrocarbon molecules, the pipe further comprising a protective layer being an outer layer relative to the barrier layer, the pipe further comprising a peelable layer between the polyolefin inner layer and the barrier layer, the peelable layer being formable around the polyolefin inner layer by means of extrusion. The protective layer and the barrier layer may together be incorporated in a single layer.
