Beschreibung
Zusammenfassung:	Spoolable composite pipes, a method of producing spoolable composite pipes, and a method for transporting a hydrocarbon fluid are provided. The spoolable composite pipes have an inner extruded tubular liner, a backer layer surrounding the inner extruded tubular liner, and a reinforcement layer surrounding the backer layer. The backer layer includes a polypropylene, and the inner extruded tubular liner includes a thermoplastic. The production method includes co-extruding the inner extruded tubular liner with the backer layer, providing the reinforcement layer, and extruding the cover layer around the reinforcement layer. The method for transporting a hydrocarbon fluid includes providing the spoolable composite pipe and introducing the hydrocarbon fluid with an aromatic content of up to about 35% by volume based on the total hydrocarbons content.
