PROCEDE DE FABRICATION DE TUYAUTERIE D'INJECTION DE CARBURANT SOUS HAUTE PRESSION |
摘要 |
The present invention provides a method of manufacturing a high-pressure fuel injection pipe in which various foreign particles are substantially completely eliminated from the inner circumferential surface of a high-pressure fuel injection pipe. The method of manufacturing a high-pressure fuel injection pipe is characterized in that the inner circumferential surface of a metal pipe having a large wall thickness and a small diameter is cleaned using a solvent for dissolving foreign particles comprising an acid, alkali or organic solvent after a final pipe-extending step among steps for manufacturing the metal pipe. |
