Abstract
Disclosed is a fluid transport pipe which has an inner layer, coming in contact with a fluid, comprising at least one aliphatic polyamide and at least one impact modifier and also at least one outer layer which is connected directly to the inner layer and is formed from an aliphatic polyamide and at least one flame retardant. While the inner layer ensures the chemical resistance relative to the fluids to be transported and the mechanical resistance, the flame resistance is ensured by the outer layer.
