Patentanspruch:Claim: Verfahren zum Auskleiden der Innenflächen von Metallrohren durch Ausschleudern mit geschmolzenem Bitumen, dadurch gekennzeichnet, daß das Metallrohr im warmen Zustande in an sich bekannter Weise mit einer Bitumenlösung z. B. Asphaltlack, vorbehandelt wird und anschließend einen Überzug aus heißflüssigem Bitumen, vorzugsweise geschmolzenem Trinidadasphalt, erhält, worauf das Rohr mit Hilfe von Wasserbrausen vorgekühlt und dann endgültig unter ständiger Drehung des Rohres an der Luft langsam abgekühlt wird.Method of lining the inner surfaces of metal pipes by centrifuging with molten bitumen, characterized in that the metal pipe in the warm state is known per se Way with a bitumen solution z. B. asphalt paint, is pretreated and then receives a coating of hot liquid bitumen, preferably melted Trinidad asphalt, whereupon the Pipe pre-cooled with the help of water showers and then finally in the air with constant rotation of the pipe is slowly cooled.
