To obtain a manufacturing technique for steel pipe excellent in internal properties for diesel engine fuel injection pipe at high efficiency and low cost.

One side 0.10-0.50mm grinding polishing is carried out by shot blasting on internal surface seamless steel pipe stock subjected to Mannesman mill piercing or mandrel will rolling and flaws are removed and further cold drawing is applied and the steel pipe for the diesel engine fuel injection pipe without any internal flaw having depth ≥0.10mm is manufactured. Thereby, the steel pipe having an excellent property equal with conventional mechanical cutting method is manufactured in high efficiency and low cost.
